About Plastic

Slippery UHMW Polyethylene Rods and Discs

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.

Antistatic Slippery UHMW Polyethylene Rods

This material suppresses static charges to prevent dust from building up.

High-Strength Slippery UHMW Polyethylene Rods

Often used in high-speed, high-precision, and high-impact applications, such as conveyor rollers and bearings, these rods stand up to scratches and scuffs better than our standard UHMW polyethylene rods. Also known as Tivar HPV.

Oil-Filled Slippery UHMW Polyethylene Rods

This oil-filled material is self-lubricating for an extra-slippery surface.

Metal-Detector-Grade Slippery
UHMW Polyethylene Rods

If a chip of this material breaks off, it can be located by metal detectors to reduce contamination risks.

Moisture-Resistant Polyethylene
(HDPE) Rods and Discs

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) Rods

One of the softest and most flexible plastics we offer, LDPE is more formable than HDPE.

Fastening and Joining

Plastic Washers

Metric Plastic Washers

Self-Retaining Washers

A specially shaped ID grips your screw shank tightly.

Low-Friction UHMW Tape Shapes

Protect small parts with these slippery UHMW rings, discs, and squares.

Light Duty Foam Mounting Tape Shapes

Tape is cut into convenient discs and rectangles.

Fire Hydrant Markers

Clearly label fire hydrants to show their flow rates, if they're out of service, or write your own message.

Adhesive-Back Bumpers

Press these bumpers into place with the adhesive backing. Use them as feet and spacers on instruments and small appliances to limit sliding, vibration, and noise. They're comparable to Bumpon bumpers.
