About Plastic

Moisture-Resistant Polyester Sheets

Polyester resists swelling in wet environments.

Moisture-Resistant Polyester Rods

Polyester resists swelling in wet environments.

Metalized Moisture-Resistant Polyester Film

An aluminum coating on one side of this film reflects heat, so it’s widely used as an insulator and in packaging applications.

High-Temperature Moisture-Resistant Polyester Film

This film is often used as a separator when heating parts in an oven.

UV- and Moisture-Resistant Polyester Rods

These black polyester rods protect from UV rays better than off-white polyester. Strong and semi-rigid, they won't swell in moist environments, so they're often made into valves, pump components, and spacers.

UV- and Moisture-Resistant Polyester Sheets

These black polyester sheets protect from UV rays better than off-white polyester. Strong and semi-rigid, they won't swell in moist environments, so they're often made into pump components and spacers.

Scratch-Resistant Easy-to-Form PETG

A satin texture on one side of these PETG sheets makes them semiclear. You can see light from the other side, but not detailed shapes. They are more resistant to scratching and glare than standard PETG.

Clear Plastic

Clear Moisture-Resistant Polyester Film

Polyester absorbs almost no moisture and resists swelling in wet environments. It is also known as PET and PETE.

Clear Static-Dissipative
Moisture-Resistant Polyester Film

A static-dissipative coating on this polyester film prevents electrostatic discharge from damaging sensitive electronic equipment.

Clear Easy-to-Form PETG Sheets

PETG can be formed into complex shapes without sacrificing durability.

Clear Easy-to-Form PETG Rods

PETG can be formed into complex shapes without sacrificing durability.

Clear Easy-to-Form PETG Tubes

PETG can be formed into complex shapes without sacrificing durability.

Clear Plastic Selector Packs

These selector packs come with one 2” square of acrylic, cast acrylic, cellulose, PETG, and polycarbonate.

Caulking Tape

Press this adhesive-backed plastic tape into place for an immediate light-duty seal.
