About Rubber

Slippery Wear-Resistant
Easy-to-Machine Acetal Copolymer

A silicone additive gives this material a self-lubricating surface that reduces friction and extends the life of your parts.

T-Slotted Framing Caps, Covers, and Seals

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

High-Temperature Rubber Sheets, Bars, and Strips

High-Temperature Silicone
Rubber Sheets, Bars, and Strips

Food Industry High-Temperature
Silicone Rubber Sheets and Strips

Made of FDA-listed materials, these sheets and strips are for use with food.

High-Purity High-Temperature
Silicone Rubber Sheets and Strips

These platinum-cured silicone rubber sheets and strips meet the strict purity standards of USP Class VI.

High-Strength High-Temperature
Silicone Rubber Sheets and Strips

Greater strength than standard High-Temperature Silicone translates into better shock-absorbing qualities and longer life.

Fire-Retardant High-Temperature
Silicone Rubber Sheets and Strips

Create a barrier against fire and smoke. These sheets and strips meet FAR 25.856 and UL 94 V-0 for flame retardance, so they emit extremely low levels of smoke when exposed to fire.

Electrically Conductive High-Temperature
Silicone Rubber Sheets

Filled with carbon black, these sheets won’t generate static charges and divert existing ones away from electronics. Use them as a conductor to protect components from static discharge.

Fabric-Reinforced High-Temperature
Silicone Rubber Sheets and Strips

One layer of fiberglass cloth is inserted between two layers of silicone rubber to give these sheets and strips the strength to stand up to high stress and flex. Use them as flange gaskets and anywhere heavy compression would squeeze nonreinforced silicone rubber out of place.

High-Temperature Rubber Rods

High-Temperature Silicone Rubber Rods

Seal and cushion channels in environments up to 450° F.

Food Industry High-Temperature
Silicone Rubber Rods

FDA compliant for use with food and beverage, these rods fit into channels and other narrow spaces for sealing and cushioning.

High-Strength High-Temperature
Silicone Rubber Rods

Stronger than standard high-temperature silicone rods, these rods are longer lasting and more shock absorbent.

Fire-Retardant High-Temperature
Silicone Rubber Rods

Meeting UL 94 V-0, these rods are flame retardant—use them to seal and cushion narrow spaces.

High-Temperature Silicone Rubber Tubes

These tubes are often used as jackets, seals, and insulation in hot environments.

High-Temperature Silicone Rubber U-Channels

The open top allows U-channels to slide over an edge. Use them as seals and trim.

High-Temperature Rubber 90° Angles

Fire-Retardant High-Temperature
Silicone Rubber 90° Angles

These 90° angles meet UL 94V0 for flame retardance.

High-Temperature Silicone Rubber 90° Angles

Seal and cushion corners with these 90° angles.

High-Strength High-Temperature
Silicone Rubber 90° Angles

With nearly twice the tensile strength of standard high-temperature silicone, these 90° angles absorb shock better and last longer.

Food Industry High-Temperature
Silicone Rubber 90° Angles

FDA compliant and NSF/ANSI 51 certified, these 90° angles are approved for direct contact with food.

Chemical-Resistant Low-Temperature Fluorosilicone Rubber Sheets and Strips

Chemical-Resistant Low-Temperature
Fluorosilicone Rubber Sheets and Strips

Temperatures as low as –70° F have no effect on these fluorosilicone sheets and strips.

High-Temperature Foam

Resilient High-Temperature
Silicone Foam Sample Packs

Resilient High-Temperature
Silicone Foam Sheets and Strips

These sheets and strips will bounce back to shape, even after extended compression.

Super-Resilient High-Temperature
Silicone Foam Sheets and Strips

This premium silicone is the most resilient foam we offer. It is equivalent to Cohrlastic and is also known as Norseal and silicone sponge.

High-Temperature Silicone Foam Sheets and Strips

Silicone maintains its flexibility across a wide range of temperatures.

Fabric-Reinforced High-Temperature
Silicone Foam Strips

One layer of fiberglass fabric is sandwiched between layers of silicone foam giving these strips strength to handle high-stress applications, such as gasketing.

Weather-Resistant High-Temperature
Silicone Foam Strips

Even after exposure to sunlight, rain, and snow, these silicone foam strips remain flexible.

Resilient Flame-Retardant
Silicone Foam Sheets and Strips

Even after extended compression, these sheets and strips will bounce back to shape.

Flame-Retardant Silicone Foam Sheets and Strips

Prevent the spread of flames with these self-extinguishing silicone foam sheets and strips.

Heat-Reflecting Flame-Retardant
Silicone Foam Sheets

A thin layer of aluminized fiberglass on this silicone foam reflects heat to protect sensitive equipment.

Food Industry High-Temperature
Silicone Foam Sheets and Strips

Seal and damp vibration around high-temperature food-service equipment with these silicone foam sheets and strips.

Thermally Conductive High-Temperature
Silicone Foam Sheets

Protect sensitive equipment from heat buildup with this silicone foam. These sheets are commonly used to fill gaps and damp vibration in computers, battery installations, and pipe assemblies.

High-Temperature Silicone Foam Cords

Seal and cushion narrow spaces in hot environments with these silicone foam cords.

Food Industry High-Temperature
Silicone Foam Cords

These silicone foam cords meet NSF/ANSI 51 for food equipment materials. Use them to seal and cushion narrow spaces in food service equipment.
