Not All Plastic Suppliers Are Created Equal

Big Differences Between Plastic Suppliers

While you can purchase a piece of plastic from many different suppliers, there are some significant differences between these suppliers. Some of the main differences are in the manufacturers and the materials that you get supplied. High quality Simona PVC rod machined to finished part

We see a wide range of materials and some drastically inferior grades of materials being sold to clients. Some materials have been produced too quickly or cooled too quickly causing a very high stressed plastic piece. These high stressed materials will warp, twist or crack when they get heated or during cutting. This material on the right is a piece of highly stressed Nylon. While cutting the material, our new customer had to stop the saw due to the severe warping and binding of the saw by this material. This new client brought this 24″ long part, and asked if we would cut it for him. We bought this part from him as an excellent example of a high stress plastic. (We did cut a quality piece of material to solve his problem).

One example of differences between manufacturers, is Gehr PVC rod is NSF 51 certified, while Simona PVC rod is not.

Other things you should consider when choosing a quality plastic supplier:

Quality of Materials

Origin of Materials

Huge in stock inventory of Performance Plastic Rod

Huge In Stock Inventory of Plastic Rod

Expert Support

In Stock Materials

Cutting – Converting Services

Longevity – How Long Have They Been In Business (We started in 1975)

Product Knowledge and Experience Equals Quality Plastic Suppliers

We believe that providing quality products is only part of our duty to you. You have intrusted us to help with your requirements, and we believe we should be good stewards of this trust, all part of being a quality plastic supplier. A plastic sheet supplier should advise you if the material you are looking for is the ‘wrong’ material. Acrylic does not do well at 450 degrees. Styrene does not make a good chemical tank. HDPE and PTFE do not bond. These and many more ‘land mines’ are things we help our clients with everyday. We have an experienced client support team (plastic experts), and we value the opportunity to assist our clients with this experience. Go ahead, ask us a question – that is why we have a “Ask A Plasticologist” page on our website.

If you need help, from what are the properties of Acetal, to temperature range on Ultem, please contact us. We look forward to assisting you and all our clients. Feel free to contact us with any questions, concerns or requests – call us at 866-832-9315 or e-mail us here.

Nylon 6, Nylon 6/6 and Nylon 6/12 – What is the best Nylon rod or sheet to use

Nylon 6, Nylon 6/6 and Nylon 6/12 – What is the best Nylon rod or sheet to use

Nylon® Rod and Sheet (Polyamide) Grades available

The Nylon® Family of plastics are all very tough, strong, machine well, and have excellent wear properties. Nylon is a very popular plastic material, and is found in numerous applications. One of the largest usages is the production of household carpeting because of the excellent wear resistance. Nylon frequently replaces materials such as UHMW, PET, Acetal Copolymer – Acetal Homopolymer, and ABS. It will outwear most plastics and is self lubricating.

The wide variety of types and colors is one of the largest in the plastic industry.Common uses for Nylon Plastic materials

Nylon® Type 6/6 Rod, Sheet and Plate

The extruded Nylon 6/6 (Nylon Rod, Nylon Sheets and NylonTubes) material (aka: Polyhexamethylene Adiptimide) is available as Natural (tan – straw), Black, Glass filled (medium tan) and a molybdenum disulphide filled which is very dark gray. The most common size range for the extruded Nylon 6/6 is .125″ – 4.0″ diameter rod, and .125″ – 4.0″ thick sheet. The thicker materials should be cast due to cost and stress issues. For addition details on the Nylon Rod and Sheet 6/6 – see the data sheet.

Nylon Type 6 Cast Polycaprolactam

The cast Nylon type 6 has almost limitless possibilities. Many colors are available in Cast Nylon, the natural color, black, blue, dark gray (normally molybdenum disulphide filled again), green and many more. Sometimes the color is determined by the additive (oil filled) or by industry. Because of its relative ease of manufacture, many companies prefer to get their Nylon in a special color to help ‘brand’ their parts.

Cast Type 6 Polyamide can be made in Nylon rod from about 1.25″ diameter to almost any size. Nylon sheet normally starts at about .75″ thickness, and

once again, can be made to almost any thickness. In addition to standard rod and plate, other sizes and shapes can be cast from Nylon Type 6 – ie. discs, tubes, near net shapes, large profiles, etc. The only limitations are how much money you have, and the size of the truck to get it to you! We have had cast very large blocks (11″ X 11″ X 48″ solid), sheaves up to 66″ OD, large tubes 36″OD X 12″ ID X 14″ long, and many more massive Nylon Cast parts.

Nylon 6/12 -Low Moisture Absorption

The claim to fame for the Nylon Type 6/12 is the low moisture absorption of the material. This grade of Nylon Sheet and Nylon rod is more stable that the type 6 or 6/6, and with the lower water absorption, this resin can handle a wider range of environments. Our manufacturer partners can run this as an Extruded Nylon Rod or Nylon sheet item or as a Cast Nylon Rod item. This opens the door to a wide range of sizes and shapes. This material exhibits most of the same properties of the Nylon 6/6 and Cast Type 6, with some slight improvements in key properties.

Filled Grades of Nylon

Because of the processing of Cast Nylon, many additives can be mixed into the material. The most common are: glass filled, oil filled, Kevlar fiber filled (Hydlar Z) and the molybdenum disulphide (M0S2). In addition, other fills and colorants (pigments) can be added to assist in manufacture or processing.

Common specifications for Nylon are: L-P-410, ASTM D-4066, L-P-395C, Mil-M-20693B Comp A, Ty I, IA, II and III, Mil-M-20693B Comp B, Ty 4, Mil-P-17091B Type 1, and Mil-P-46060, PA0613, ASTM D-5989 S-PA0511, and more.
