A wide variety of plastics are available in sheet form.
The term: ‘Plastic Sheet‘ or ‘Plastic Sheets’ is more of a general statement covering over a hundred types of plastic materials and plastic products. Some of the most popular plastic materials made as a sheet are:
In addition to the wide range of plastic materials available as plastic sheet, most of these materials are also available as: thin gauge or film, strip, plate, block, slab and plastic panels. The thin gauge or film materials are frequently available with or without a pressure sensitive adhesive also called ‘tape’. Sheet in some materials is available over 4.0″ thick and perhaps as thick as 8.0″ thick in a few materials. The standard sheet size on most of our plastic sheets is either 24″ X 48″ or the larger 48″ X 96″ sheet size; although some materials are available as: 48″ X 120″, 60″ X 96″ or 72″ X 96″. Contact us with with questions on your required piece sizes, we are happy to provide plastic sheets cut to size.

Today’s topic is all about industrial plastic sheet materials in flat sheet or sheets. Also known as plate, slab, strip and bar.
Most plastic materials are processed into sheets or rods. Rods are round, sheet is flat, square or rectangular. These two basic shapes are both generally extruded, although sheet can also be compression molded. Almost all plastic raw materials are available in sheet, and in a huge range of sizes. Most materials are available from .063″ to over 4″ in thickness; and some as thick as 8″ (how to measure thickness accurately, use a 6-Inch Digital Caliper with Extra-Large LCD). Sheet sizes vary, but generally most plastics are produced in 48″ X 96″ sheets or larger, but once again this changes with types of materials and thickness desired. We can help with almost any plastic material.
Need Help Picking a Plastic Sheet Material?
Deciding on the proper material for an application is the first step. Start by reviewing our Plastic Materials Selection Guide to help narrow your search. Having the key properties and needs of your project in mind will help you with this step. Also looking at both the pro’s and con’s of a material will assist in this search. Materials with the greatest property range can be extremely expensive, selecting a material that meets your needs and your budget should be considered.
Step two is researching sizes and availability – this is where we can really help. With most of the major manufacturers as partners, we are able to source your parts from many factories. While the quality from most factories is excellent, the variable is standard and custom sheet sizes. We also stock a wide variety of materials in large sheets. One of our many manufacturers is Westlake Plastics. They have been compression molding large sized sheets of many popular plastic resins; these sheets are available in 48″ X 120″ as a standard sheet size in most plastics. They produce these materials from .250″ – 3.0″ thick or thicker. Other manufacturers produce 24″ X 48″ or 48″ X 96″ sheets as standard. Please contact us for specifics on your material selection.
Mechanical Acetal Sheet
Most of our plastic resins are available as a sheet. This includes some of the most popular plastics, like: Polycarbonate Sheet, Acetal Sheet, PTFE Sheet, Ultem Sheet and dozens more. Sometimes, Plastic sheet is called: Plate, Strip, Bar, Slab, Block or Panel. Please think of these names as being synonyms with Plastic Sheet. Contact us with your special requirements.
In thicker gauges, plastics are frequently referred to as plate, slab or block. And strips or narrow pieces are called bar. A rose by any other name, call it what you will, the plastic starts as a flat sheet from the factory. We can cut them to size or shape. Blanking of sheets to useable sizes is our specialty. Narrow pieces used for long applications are normally called strip. Strip is common in wear type applications.
For a list of materials we have as standard stock materials, check our Plastic Sheets Page. These and many other plastic materials are available, and custom sizes, shapes and colors vary by base material. As a stocking distributor for dozens of major manufactures, we are the West Coasts leading plastic sheet supplier or distributor. If you are in need of some technical assistance go to our Plasticologist page for specific help.

When we think of plastic, we think of plastic bags you get at the grocery store or maybe your child’s toy that’s made out of cheap throw away material. If you stop and think about it, plastic is everywhere and it’s uses are almost infinite. Take Acetal Copolymer, it is a plastic that replaces metal in numerous applications and is used to make gears, screws and other hard working parts. Consider PTFE for instance which is used to coat your frying pan to make it non-stick, make steam valves and fittings, and chemical resistant parts. Another material is Polycarbonate or Lexan® (a SABIC brand name -formerly G.E. Plastics) which is used to replace glass because it is shatter resistant and is also used for bullet resistant glazing and riot shields. Even the cup of coffee you grab for every morning is made of foamed Styrene – Styrofoam. But plastic has shaped our lives in countless ways, many of them you might not even think of or notice.
Plastics play a big part in the world of medicine. Some other advancements in the area of medicine include assisting people with debilitating injuries and serious afflictions, helping them feel more comfortable and move easier. Prosthetic limbs and joint replacements have come along way since the old days of metal and wood. Since the late 90’s UHMW or (Ultra High Molecular Weight Polyethylene) has become the standard in hip and joint replacements. With plastics like UHMW, which has great wear resistance, excellent strength and very low co-efficient of friction (very slippery), it has made people who need these surgeries have better mobility and better quality of life. These plastics also make prosthetic limbs lighter and stronger for athletes who wish to compete and lead near normal active lifestyles due to the use of plastic polymers (derived from the Greek meaning ‘many parts’) mimicking human flexibility. Prosthetic devices date all the way back to the ancient Egyptians where they used leather and wood for toe and foot replacements. But thanks to today’s technologies and advancements in as plastic, most amputees and athletes can regain their quality of life and enabling them to do what they love.
What has Medical Plastic Done For You Lately?
Another plastic material that has changed the medical field is PEEK (Polyetheretherketone). This material is a newer plastic which has high chemical resistance along with excellent high continuous temperature resistance of up to 480 degrees fahrenheit. PEEK has replaced many metal devices in the medical field, because PEEK is one of the only thermoplastics (plastic which can be bent or shaped) able to withstand high doses of radiation over an extended lifetime. In addition PEEK is used to help many people awaiting kidney transplants because it is used to make a critical component in dialysis machines. These machines need to clean the blood over a period of several hours and because of this, PEEK is the natural solution, as it can be steam cleaned time and time again with little effect on the material. Along with its great chemical, temperature, and fluid handling stability, PEEK is USP Class VI, making it ideal for these types of medical applications. The natural color of PEEK is a beige to tan and is available in sheet and rod. One of the largest manufacturers of PEEK resin is Victrex and their 450G resin.
Plastics In Medicine – Everyday
Plastic materials have become apart of our lives and has changed the way we take care of the sick and injured, how we protect our foods from germs, and prolong the storage of foods. Plastics protect medical instruments and insure they are sterile. It has made people’s lives better in both the short and long term. It has helped reduce pain, gain better movement and has given people their confidence back. The values of plastic can not be understated and in the future, hopefully plastics will save or prolong many more lives through advancements in technology and the limitless possibilities it presents.

Over the last 50 years or so since plastic became more and more prevalent, over one billion tons of it has been disposed of and that number only continues to grow. Plastic, because of its molecular structure does take along time to decompose and cannot be burned due to it releasing harmful toxins and pollutants into the air. However since the mid 1990’s, plastic recycling has become more advanced and a greater awareness has been established. Since this time though, new technologies have been implemented making it easier to recycle and making people more conscious to do so. Curbside containers and designated recycling stations have vastly improved the way we dispose of these materials. These programs helped pave the way for a new era where plastics are less likely to be littered on the side of the road and to make it easier to be reused over and over again saving money, energy and helping the environment.
Some of the main plastics which can be recyclable are:
Polyester or PET carries the number 1 symbol. This plastic is primarily used for soft drink bottles. It is the easiest to recycle plastic and can be reground and reused time and time again.
The plastic with the number 2 symbol on it is HDPE which is a plastic primarily used for grocery bags, milk jugs and laundry detergent bottles.
PVC has the number 3 symbol and is used for pipes, fences and non-food containers.
LDPE is number 4 and is used for tubing, caps, rings and shrink wrap (coffee can lids).
Polypropylene has the number 5 symbol and its uses are for automotive parts, food containers and dishware.
Polystyrene is number 6 and is used for food containers and cups (including Styrofoam).
7 is other material such as Acrylic, fiberglass and Polycarbonate. These plastics are used for lenses, glasses and shields.
ABS is the number 9 symbol and is used in automotive, model building and molded parts.
Join the grass roots groups to recycle
Many schools and organizations work to collect and recycle materials, including plastics and aluminum cans. The biggest problem with plastic recycling is that it needs to be so meticulously carried out and requires painstaking time to sort properly and to go through the plastics. This is why the resin identification coding system was implemented in 1988 to help better identify plastics. The number in the middle has no real significance and is just there to help name the plastic the item is made from. This system has greatly improved the way plastics are handled and recycled leading to greater efficiency and better consistency when sorting through plastic resins.
There are, however, some plastics that cannot be recycled. These plastics are called thermosets, which are plastics that cannot return to their original form. The best example of this type of plastic is Phenolic which was the first commercially available plastic back in 1907, and was originally called Bakelite. It is primarily used for electrical and mechanical purposes. Unlike thermoplastics which can be formed and returned to their original shape, thermosets cannot due to their chemical makeup and they frequently have additives or fillers. Thermosets form above the melting temperature so when they are heated, the decomposition temperature is reached before the melt point.
Many of these thermoset materials replace other, much more expensive materials, and generally out last the former material by as much as 20 times. In practice, these material reduce the usage of natural resources and the ‘carbon footprint’ used to produce the items. One such material is the Nylon bushings used in large ships. The Nylon replaces a large Bronze bushing that used to be replaced once a year, and required the ship be put into dry dock to remove and replace the bushing. The new Nylon bushings out perform the bronze, and will last over 12 times longer. Dramatic savings in materials, casting new bronze bushing and the loss of sailing time of these ships.
Thanks to recycling improvements in the last 25 years, recycling has become much more efficient. Because of these programs better care has been taken to insure that plastic is not littered or discarded lightly, and that the programs created are easily accessible so people can take better care of their trash and better care of the earth. Plastics manufacturer commonly work to reuse and recycle materials during production. Many materials are available as ‘reprocessed’ or ‘commercial grade’ materials, meaning they contain a percentage of material that has been processed before. The first time a plastic resin is sent through the manufacturing process, that resin is referred to as ‘virgin resin’. Any further processing, the material must be referred to as reprocessed.
