High Impact Polycarbonate Sheet and Rod

Polycarbonate sheet material is used frequently for shields, guards, and containment barriers.

It can be cold or heat bent to most configurations. A popular material manufactured by several companies: Lexan® by SABIC, Tuffak® by Plaskolite (formerly Makrolon® by Covestro), Zelux® by Westlake, Unicar® by Nytef Div of Polymer, Ensicar® by Ensinger, Cyrolon®, Polygal®, Plazit®, Tuffak® GP, Paltuf®, Texin®.

Today, there are numerous versions of these Polycarbonate resins, produced by a dozen different resin manufacturers; however Lexan® and Makrolon® still lead the field.

In addition to the large number of resin manufacturers, there are also dozens of extruders that can produce the Polycarbonate in Sheet or rod.

The leaders are Tuffak Plaskolite (formerly Covestro), SABIC Lexan and Plazit Polygal. All three have extrusion equipment in the USA and produce high clarity and high quality Polycarbonate sheet.

Some of the leaders in the Thick Plate and Rod extrusion are Ensinger, Westlake, Rochling, Polymer and Gehr Plastics.

Why you should use Polycarbonate:

Polycarbonate sheet is a common material for a variety of glazing applications, impact resistant shields and formed parts. Polycarbonate Sheet and Rod are generally produced from plastic resin produced by two main plastic resin manufacturers:

1) Plaskolite (formerly Covestro Plastic) produce Tuffak® Polycarbonate (formerly Makrolon®) sheets as well as a full line of Acrylic Sheet and Acrylic Mirror materials.

2) SABIC (Saudi Arabia Basic Industries Corporation) Plastic, producing a wide range of plastic resins including: Lexan® Polycarbonate, Cycolac®, ABSNoryl®- Poly Phenylene Oxide (PPO)Ultem® 1000 and Ultem® 2300 PEI resins.

The general purpose Polycarbonate resins are about the same as they were when they were first invented. The research on this resin started in 1898, but was first perfected by Bayer in Germany and was patented and registered in 1955. Amazingly, one week after the first invention by Bayer, Daniel Fox at General Electric in New York, independently synthesized a branched Polycarbonate resin.

Both companies filed for US Patents in 1955, and agreed that the company lacking priority would be granted a license to the technology. The patent was resolved in Bayer’s favor and Bayer began commercial production under the trade name Makrolon® in 1958.

GE Plastics began production under the Lexan® trade in 1960.

Polycarbonate is ITAR compliant, and Polycarbonate is RoHS compliant.

Is Tuffak Polycarbonate The Strongest Plastic in Sheets?

Is Tuffak Polycarbonate The Strongest Plastic in Sheets?

What is the Strongest Plastic – Polycarbonate Sheet?

Many plastics are durable and have good impact strength. Acetal Copolymer – Acetal Homopolymer for example is a very durable and strong material, but compared to some other materials the impact strength is lower. The Acetal  is the best machining plastic around, it is used to make long lasting and good wearing parts for machines. Another great plastic that holds up to wear and tear is UHMW. With its high molecular weight and low friction resistance is ideal to take abuse over long periods of time. Plaskolite Tuffak Polycarbonate sheet for riot shields

However, one of the strongest materials in the plastic family is Polycarbonate. Commonly referred to Lexan® (SABIC) or Makrolon® (Bayer) Polycarbonate Sheets; Polycarbonate is by far one of the strongest (highest impact resistant) ­­­­­plastic materials, and is warranted against breakage. With its high impact strength, it is ideal for jobs were the ability to absorb abuse is a factor and in some cases may even need to save lives. A common material for high impact is Polycarbonate Sheet and Plate, but amazingly also Polycarbonate Rod.

Polycarbonate Sheets considered ‘unbreakable’.

Polycarbonate sheet is a valuable plastic due to its impact strength, temperature resistance and wide range of uses. It is commonly confused with Acrylic or Plexiglass which has similar properties but Polycarbonate is 25 times stronger and has a wider temperature range. Acrylic is better used for display purposes and is a brittle material. Polycarbonate is so strong that you can drill or hammer a nail right through it without breaking the material. It also can undergo large deformations without breaking while Acrylic cannot. Polycarbonate also can be used for electrical applications because it is a great insulator. It also has great safety properties due to it being flame retardant and because it has good heat resistance. Another way Polycarbonate exhibits its safety properties is through bullet resistant glass. Polycarbonate is the most commonly used material for bullet resistant glass, riot shields and face masks. In these situations, the Polycarbonate has a very high impact strength which is invaluable. It protects and saves lives and is able to stand up to abuse in dangerous situations.

Polycarbonate Has Many UsesTuffak Polycarbonate Sheet from Plaskolite

From audio CDs to Blu-ray discs, airplane canopies to protective eye gear, Polycarbonate is a great thermoplastic (a material that can be formed and returned to its original shape) material for many different applications. Because of its impact strength and wide range of uses, Polycarbonate makes an ideal material for those who need peace of mind when designing or fabricating and need it to hold up to abuse and be virtually unbreakable. Polycarbonate is one of the toughest plastic materials around and everyday new products are being made from it. Whether using it for electrical, optical or for its impact properties, Polycarbonate is an ideal choice for many plastic needs.

Polycarbonate sheet (Makrolon) is available from .032″ – .500″ thick

Available Plastic Sheet Material

Today’s topic is all about industrial plastic sheet materials in flat sheet or sheets. Also known as plate, slab, strip and bar. Acetal Copolymer and Dupont Delrin Rod

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.
