About Rubber

About Structural Adhesives

High-Temperature Silicone Rubber Sheets, Bars, and Strips

Also known as polysiloxane, this silicone rubber offers good resistance to ozone and salt water. Softer durometer rubber has better conformability; harder durometer rubber is more wear resistant.

For adhesive-back sheets and strips that are FDA compliant, the silicone rubber meets the standard, but the adhesive does not.

Self-Fusing Electrical Tape

Tape

Tape with Guide Line and Tapered Edge

No need for adhesive—this tape fuses to itself for a permanent seal and stretches to fit virtually any form. Also known as cold-shrink tape.

Tape with guide line has a ridge in the center and a tapered edge that allows for an even overlap when wrapping.

High-Temperature Glue-on-a-Roll

This silicone glue withstands high temperatures and bonds slippery plastics. Also known as adhesive transfer tape, these rolls have a thin film of pressure-sensitive glue on a peel-away liner. They are thinner and more conformable than tape with adhesive on both sides.
