About Plastic

Slippery UHMW Polyethylene
Sheets, Bars, and Strips

In addition to a low-friction surface that prevents sticking and binding, this tough material is impact and wear resistant to handle the scuffs, scrapes, and strikes that other plastics can’t.

Moisture-Resistant Polyethylene
(HDPE) Sheets, Bars, and Strips

Practically nonabsorbent, HDPE won't swell when exposed to moisture. It is denser and more rigid than LDPE, plus it's more chemical resistant.

Wear-Resistant Easy-to-Machine Delrin®
Acetal Resin Sheets, Bars, and Strips

Delrin® acetal resin, also known as acetal homopolymer, is stronger and stiffer than acetal copolymer.

Wear-Resistant Easy-to-Machine
Acetal Sheets and Bars

An economical alternative to Delrin® acetal resin, this acetal copolymer offers similar wear resistance.

Chemical-Resistant PVC Sheets and Bars

Because PVC resists many acids and alkalies, it’s widely used for tanks and in chemical-processing applications. Also known as PVC Type 1.

Wear-Resistant Nylon Sheets, Bars, and Strips

Also known as nylon 6/6, this general purpose material is often used for bearings, gears, valve seats, and other high-wear parts.

Easy-to-Machine Wear-Resistant
Cast Nylon Sheets and Bars

This cast nylon 6 material is easier to machine than other types of nylon. It’s comparable to Nylatron and Nycast.

Heat-Stabilized Easy-to-Machine
Wear-Resistant Cast Nylon Sheets and Bars

Often used to make gears and wear strips, these cast nylon 6 sheets and bars withstand higher temperatures and are easier to machine than standard nylon 6/6 sheets and bars.

Oil-Filled Easy-to-Machine Wear-Resistant
Cast Nylon Sheets and Bars

This nylon stays lubricated over time because it’s filled with oil. Use it to fabricate parts for hard-to-reach places where adding lubricants would be difficult.

Polypropylene Sheets and Bars

Because this polypropylene resists swelling when exposed to water, it’s often fabricated into containers and parts for laboratory equipment.

Clear Scratch- and UV-Resistant Cast Acrylic Sheets, Bars, and Cubes

Clear Scratch- and UV-Resistant
Cast Acrylic Sheets, Bars, and Cubes

Cast acrylic is easier to machine than extruded acrylic. It's comparable to Lucite and Plexiglas® Acrylic.

Heating, Venting, and Air Conditioning

Contoured Sound-Absorbing Sheets

Also known as egg crate, these sheets have peaks and valleys that absorb more sound at higher frequencies than flat-surface sheets. Use them to quiet noisy areas and line machine enclosures. Sheets are made of humidity-resistant polyurethane foam.

Flexible Fiberglass Duct Insulation Sheets

Wrap rectangular and round ductwork with this flexible insulation.
