Soft density Silicone sponge Soft density silicone sponge is with high grade silicone rubber material and inimitable technique, with Good character of high temperature resistant, aging resistant, ozone resistant, insulation property, fuel Oil resistance, lubes resistance, no smell and wear well. High compressibility and low compression set Over a wide temperature range, and good acoustic and thermal insulation properties. Apply to -50C ~+200C protect and heat insulation for long term continuous use and -70C ~ +260C for intermittent Use on all kinds of machine.
