I'm a private individual and would like to make a purchase. Will you sell to me, and do I have to buy full size sheets?

We sell all of our plastics to individual consumers either through our Retail Store or over the internet. We’ll gladly cut to size most any plastic materials you might need. You’ll find the same courteous and helpful service whether you are purchasing a 12″ x 12″ piece of Plexiglas® for your basement window, or buying a truck load of plastic sheet for your business!

What printed information is available?

We have Specification Sheets, Information Sheets, and Price Lists available now.

Are samples available?

Yes, please contact our inside sales crew.

What are the working temperatures of plastics?

The correct definition for the “working” temperature of a plastic is how hot it can become and still function normally. Most plastics can go -40 degrees F and retain their physical properties without becoming overly brittle (except flexible vinyl convertible windows). There are special cryogenic grades of plastic (G10 and UHMW-PE) that will go below -400 degrees F! For the most part, most plastics will soften or lose their structural properties around 200 degrees F. The chart below lists a few of the most popular plastics and their maximum continuous working temperatures.

What are the different UL 94 flammability rankings?

UL 94 5 VA – best or most flame resistant; UL 94 VO, UL 94 V1, UL 94 V2, UL 94 HB – lowest or most likely to flame.

What is the difference between an ASTM primary specification and an ASTM shapes specification?

The primary ASTM specification refers to the raw material and calls out minimum properties for injection molded samples. The shapes specification is valid for semi-finished products such as extruded acetal rod, plate or tube. As processing differs by supplier, calling out a shapes specification assures a customer of a quality semi-finished product. Calling out a primary specification only assures a customer of quality resin prior to processing.

Do you offer traceability?

Complete traceability, lot and batch information, and dates of manufacture are available on most all products. Requests for this information must be made at the time of placing an order. Requests after shipment may not be able to be fulfilled.

Is 1/4 plastic really 1/4 thick?

It depends on what kind of plastic you buy. Most engineering plastics (Nylon®, Delrin®, Teflon®, etc.) are sold “thick” – with standard tolerances of -0.0″ to +5% because the machinist needs the extra material for exactness. This is also true of the rod and tube in these grades. However, there are many plastics that are sold in metric thicknesses with English widths and lengths. Acrylic, such as Plexiglas®, is sold this way. The table below should help you be more informed about what you are getting. Please be aware that some plastic companies in the U.S. may substitute .098″ for .118″ and .220″ for .236″. If you receive a price quote substantially lower than ours, you may want to measure the sheet they are selling.
