About Plastic

Clear Chemical-Resistant PVC Film

Because PVC resists acids and alkalies, it is often used in tanks and chemical-processing applications where visibility is essential.

Clear Static-Dissipative Chemical-Resistant PVC Film

Carbon mesh is embedded into this clear PVC film to dissipate electrostatic discharge and protect sensitive electronic equipment.

Clear Static-Cling Chemical-Resistant PVC Film

Static cling allows this PVC film to stick without an adhesive.

Clear Clean-Release Polypropylene

Also known as frisket film, this polypropylene has a low-tack adhesive that releases without leaving residue behind.

Moisture-Resistant Polyethylene (HDPE) Film

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

Flexible Polyethylene (LDPE) Film

Often used for packaging and construction applications, this film is also known as Visqueen.

Reinforced Flexible Polyethylene (LDPE) Film

A polyester string reinforcement gives this material better tear resistance than standard LDPE film.

Chemical-Resistant PVC Film

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

Fabric

Tyvek Polyethylene Fabric

Composed of high-density polyethylene fibers, this durable material is tear and water resistant and keeps its high strength in both wet and dry environments.

Polyester Fabric

Often used as outdoor equipment covers and pit liners, this material combines UV, water, and mildew resistance with tear resistance.

Ultra-Weather-Resistant Nylon Fabric Sheets

The neoprene coating on these nylon sheets resists UV rays as well as solvents and oil.

Water-Repellent Cotton Fabric Sheets

Saturated with wax, these sheets also have a polyester coating on one side to resist corrosion and moisture. Protect piping and wrap irregularly shaped objects with this very flexible fabric.
