About Plastic

Compare over 25 types of plastic to find the right material for you.

Raw Materials

Polypropylene Sheets and Bars

Polypropylene Sheets and Bars

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

Polypropylene Rods

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

Polypropylene U-Channels

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

Polypropylene 90° Angles

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

Polypropylene Tubes

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

Flame-Retardant Polypropylene Sheets

Flame-Retardant Polypropylene Sheets

Widely used in semiconductor applications, this polypropylene meets UL flame-retardance standards.

Clear Clean-Release Polypropylene

Clear Clean-Release Polypropylene

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

Synthetic Felt

This synthetic felt is an economical alternative to wool felt.

T-Slotted Framing Caps, Covers, and Seals

T-Slotted Framing Caps, Covers, and Seals

Seal T-slots, rail ends, and gaps between rails to keep out dust, debris, and other contaminants.

Plastic Pipe and Pipe Fittings

High-Purity Polypropylene
Pipe for Corrosive Chemicals

The inside of this pipe won’t leach contaminants into your line or accumulate particles—it’s polished to an ultra-smooth 12 Ra finish, which also makes it easy to clean. Made of polypropylene, it resists organic solvents, acids, and alkalis better than CPVC pipe.

High-Purity PVDF Pipe for Corrosive Chemicals

Made of PVDF that’s finished to a 12 Ra smoothness, this pipe handles some of the harshest chemicals without leaching contaminants into your line.

UV-Resistant Polypropylene Pipe for Chemicals

This polypropylene pipe resists the damaging effects of ultraviolet light, so it’s suitable for outdoor use. It has the chemical resistance to withstand acids, solvents, and other harsh substances.

Gravity-Flow Polypropylene Pipe
for Corrosive Chemical Waste

Made of polypropylene, this gravity-flow pipe stands up to tough organic solvents, such as acetone, that would dissolve CPVC pipe. You can also use it for lines with highly corrosive acids, such as hydrochloric acid, and alkalies.

Semi-Flexible Plastic Pipe for Water

Semi-Flexible Plastic Pipe for Water

Connect to barbed plastic pipe fittings with a clamp. Pipe isn't as bendable as soft tubing, but can still bend around objects, resulting in fewer connection points in your line. Fewer connection points not only shortens installation time, but also allows for smoother flow through the line.

Underground Snap-Lock Polyethylene
Pipe for Drain, Waste, and Vent

Underground Snap-Lock Polyethylene Pipe for Drain, Waste, and Vent

Pipe has a snap-together design that allows you to quickly connect to fittings with no cement required. It is typically used in gravity-flow drainage applications.
