Available Materials Plastic Strip and Strips For Food Processing and Material Handling

Plastic Strip is common in other materials

A common standard item in the metals industry is ‘strip’. Strip is normally a piece of material that is 1/16″ – 3/8″ thick and 1.0″ – 4.0″ wide, although thicker and wider materials can also be referred to as strip. The metals industry produces various metals in these sizes of strip. In the plastics industry, strip is something we cut from larger sheets. The sizes are the same as listed above, but are cut from 48″ X 96″ or 48″ X 120″ sheets.

The a few of the most common plastics materials we cut to plastic strips are:

HDPE (High Density Polyethylene)

PTFE, TFE (Polytetrafluoroethylene)

UHMW – Ultra High Molecular Weight Polyethylene

Acetal Copolymer / Acetal HomopolymerPlastic Strip, plastic Strips and Plastic Tapes, Plastic Bar

Nylon – Polyamide

PVC – Polyvinylchloride

Polycarbonate – Covestro (Bayer) Makrolon

Most plastics can be cut to these strip sizes, with various lengths available depending on type of material. In some materials and in some sizes, depending on quantity, special run to size plastic strip is available. These special run plastic strips can be run to almost any length. Specifically, in the UHMW and PTFE materials, much longer lengths are available in rolls of material. The UHMW can be purchased in standard and adhesive back varieties. This UHMW with adhesive is a commonly used item in the wear strip applications because of its ease of installation. A large market for this kind of strip is in the food processing industry for all wear points and to reduce noise in the plant. Some of these same sizes with adhesive on the back are available in the PTFE, and are available in long tape style rolls. In some cases, colors other than natural are available, contact us for details.

Plastic Strip and Strips are available in special sizes

With the massive range of plastics available, and most of these materials available to be cut to strips, the nearly unlimited amount of choices in plastic strip availability make this post difficult to be all inclusive. Great material for the industrial, food processing, material handling, automotive and recreational industries.

Most plastics are available in large sheets, and we can cut these sheets to strip for you. Also, depending on the material, size and quantity, we can custom extrude your strip in longer lengths and to your requirements. Decide on a type of plastic, determine the size and quantity, and give us a call. Use your imagination, we can help.

If you have a project where strips would be ideal, please contact us to see if the type of material you need is available in the strip configuration that would be beneficial. Call us at: 866-832-9315 or drop us an email and we will be happy to go to work on your requirement.

Are HDPE sheet and Homopolymer Acetal Sheet The Same Materials?

Are HDPE sheet and Homopolymer Acetal Sheet The Same Materials?

Is HDPE Sheet and Acetal Homopolymer Sheet the same?

Here is another popular question asked by our clients. Is HDPE the same as Acetal Copolymer  / Delrin Acetal Homopolymer?
No, they are two totally different materials. Although the natural color of both is a milky white to opaque white, and they do look a bit similar, they are not. (HDPE is milky white to almost translucent depending on thickness, and the Acetal materials are a more opaque white to slightly milky – once again depending on thickness . See picture below of .500″ thick samples of HDPE and Acetal sheets)HDPE compared to Delrin Acetal Homopolymer sheet

HDPE and Acetal – Some Differences

The HDPE sheet and rod is a softer material, and is commonly known for its FDA certification and used in numerous food applications, such as: one gallon milk jugs, cutting boards, colored water glasses/cups, and many, many more. While it can be machined, because it is a bit softer and lighter, the tolerances it can be machined to are not very tight. It is not bondable, so it makes a great non-stick surface for sticky foods and adhesives.


The Acetal Copolymer and the premium Delrin® Acetal Homopolymer also have FDA certification, and are used heavily in the food processing industry. This material is a more mechanical material and is used in bearing and wear applications, cams, feeder screws, etc. This material is can be machined to tight tolerances, and will wear for long periods without lubrication. Due to its exceptional wear properties, it is not bondable, thus requiring mechanical fastening or threads to assemble. It has a very low water absorption, and you will find it in your toilet tank as the white moving parts in the filler mechanism. It is an extremely popular material for machinists, as it works much like soft brass.


While HDPE Sheet and Acetal Sheet look similar, they perform quite a bit differently.

While both materials are FDA approved, are machinable and can be used to make rigid wear resistant parts, they are two different resins and have drastically different physical properties. Another major difference is in the weight of these items, HDPE sheet and rod material weighs about 35% less than the Acetal sheet and rod material. Please check the data sheets for more information to assist in proper material selection. Acetal Data Sheet and HDPE Sheet Data

Acetal is commonly known as: Delrin Homopolymer Acetal, Tecaform AH,Ensital, Unital, Pomalux, Ultraform and many more.

HDPE is also known as: Ultraethylux, Densetec, Polystone G, Fortiflex, Versadur, Hostalen, and many more.

Nylon Tube and Nylon Tubing made from Nylon 6 or Nylon 6/6

Nylon Tube and Nylon Tubing made from Nylon 6 or Nylon 6/6

Nylon Tube and Tubing can be made from Nylon 6 or 6/6

Nylon is one of the most popular and widely used plastic materials. From the carpet in your home to the yellow Nylon rope you have in your garage, Nylon is a tough and very wear resistant material. This self lubricating mechanical plastic material is very stiff and extremely durable. This material can be machined easily, and is a key industrial plastic resin.

Nylon 6 and Nylon 6/6 Tubing

While Nylon is a common plastic material, in the extrusion and cast grades, it is not a normal stock item for many factories. Nylon can be produced in a huge range of sizes. The cast process enables the range of sizes of a Cast Nylon Tube (Type 6) to be almost unlimited. The extrusion process is a bit more restrictive, which can produce very small sizes to larger sizes of Extruded Nylon Type 6/6 Tubing up to about 2.0″ OD. The properties of these materials are similar, and are listed here. Also, in the case of the Cast Type 6 Nylon Tube, many additives can be mixed into the casting Red Cast Nylon Type 6 Sheet and Platemixture to increase many critical properties. Examples of these additives can yield: Glass Filled Nylon Tube, FDA Approved Oil Filled Cast Nylon Tubing, Cast Nylon MD Tube (molybdenum disulfide), Solid Lubricant Filled Cast Nylon Tube, and a few additional variations. These same filled items are also available in Cast Nylon Rod, Cast Nylon Sheets and Cast Nylon Plates (all made from the same Cast Nylon Type 6 resin). This casting process allows for a wide range of sizes and configurations, from round rod, cast sheet, tubular bar to near net shapes and covers on metal rollers and gears.

Why use Tubular Nylon (Nylon Tubular Bar)

There are numerous reasons to use a Nylon Tubular shaped material. 1. Vast range of sizes to fit most requirements 2. Large reduction of waste due to near net shape 3. Great reduction of machining time due to matching size to finished needs 4. Lower cost due to reduced material and reduced machining time

The difference between Nylon 6 Tubing and Nylon 6/6 Tube

The main differences are the base resin. The Nylon 6 tubing is a cast resin, and the Nylon 6/6 tube is an extrusion grade resin. Both materials are still Nylon, just a different grade of resin. The properties are also very similar, look here for specific Nylon resin properties. The other difference is that the Cast Type 6 Nylon is normally in larger sizes. This is because the cast version is poured as a liquid into molds or rigid tooling, and is done one at a time. This process, while it makes a very high quality part, is a more expensive manufacturing method, and is not cost effective in small or thin cross sections. The extrusion grade of Nylon, the Type 6/6 Nylon is heat processed in large batches. This process requires set up and large runs, and is very cost effective in these large production runs. In addition, the cross sections for the heat processed Nylon 6/6 can not be excessively large. The extruded Nylon 6/6 is therefor done sizes up to about 3″, as larger pieces are more expensive and require extra stress relieving to prevent warping.

Cast Nylon VersatilityLarge Cast Nylon Sheave

The Cast Nylon manufacturing in the USA is very advanced. The production facilities can produce amazing and diverse sizes and shapes in the grades listed above. One of the unique versions of Cast Nylon is in the Glass Filled Nylon Tube, Glass Filled Nylon Rod and Glass Filled Nylon Sheet range. The percentage of glass fill can be custom blended to meet your specific needs, and can also contain additional fillers like MD, Oil or pigments. Many grades of Nylon are also available for very specific applications, like: bearings, sheaves, pulleys, wear plates, food processing applications, FDA approved grades, color matched for identification and many more. Other plastic materials used in these same applications include: Acetal Copolymer, PET (Polyester), PTFE and more.

Is Nylon Food Grade

Is Nylon Food Grade

Is Nylon Rod and Sheet Food Grade

This question was very easy to answer, up until now.

First: what is Zytel 42? It is a Natural Nylon 6/6 extrusion grade plastic resin. An extremely popular and heavily used material for machinable and durable plastic parts. For as far back as we can find information, this Zytel 42 Nylon 6/6 resin has been used in numerous food contact and food processing machine components.

We have just received notice that Dupont will be making some changes to their formula for this Nylon grade. For years we have provided our clients with Dupont Zytel 42 Nylon resin extruded into sheet, rod and other profiles. The Dupont announcement states that the Zytel 42 will no longer have a food grade rating – FDA approval. They will produce a new resin called Zytel 42FG, which will have all the approvals we always had with the Zytel 42.

Why in the world would a company do such a thing? Our guess is that this is a cleaver way to increase prices significantly without a standard and blatant price increase. Let’s just hide it in a new resin package.

Nylon Sheet, Nylon Slab and Nylon Rod are all available as these:

Zytel 42 – will still be available, but without the FDA approval

Zytel 42FG – the ‘new’ resin will carry the FDA approval, but at much higher price

Nylon Food Grade still available

Large Cast Nylon Blocks 12" X 12" X 48"

These huge Cast Nylon Blocks 12″ X 12″ X 48″

What is the difference between the old Zytel 42 and the new Zytel 42FG? From what we have read so far, nothing. It is probably the same material, new name. The ‘new’ Zytel 42 is actually the new ‘dumbed’ down resin – they just took away the Food Grade label, maybe took out an ingredient or two, and viola, new Zytel 42 – non Food Grade Nylon.

This news has spread quickly through our industry. As mentioned above, we have provided this material in this grade for over 36 years for Food Grade/FDA Approved applications.

The main reason for this article is to get the news out the the marketplace. Engineers and designers have been specifying this resin for their applications, and now, with out much notice, the product they assume is Food Grade will no longer be acceptable for these applications. It is unclear at this point whether the extrusion plants will be producing product from both resins, or opting to use one or the other. It appears that Nylon Food Grade resins my become a special, or that all materials may becomes standard as Nylon Food Grade.

Is Nylon Food Grade Resin Important To You?

This is the question we find ourselves asking. Does the end user think of Nylon when they are looking for an FDA approved plastic? Or, do they consider Acetal Copolymer, Acetal Homopolymer, Polyethylene, and other materials first? Do you think of Nylon rod, bar, sheet and slab as mechanical materials to use when making gears, wear strips, and other non FDA applications?

Please take a moment and let us know you thoughts. We value your input – it will help us in evaluating the direction we want to go with our inventory.
