DATA SHEET FOAM SILICONE

Product catalog summary

Overview
Silicone rubber can be expanded into a silicone sponge using blowing agents. This silicone sponge is an excellent sealing medium due to its stable chemical structure and good recovery. It can be extruded into profiles or produced in sheet form, which can be joined or mitred to form continuous seals.

General Properties

Minimum water absorption (IP65-66 achievable)
Good UV and corona resistance
Good arc and ozone resistance
Practically non-existent oxidation
Excellent for damping and vibration components
Generally resistant to moderate chemicals or oxidants
Excellent resistance to heat stroke
Complies with FDA 21 CFR 177.2600 sections e-, f
