General Characteristics
SS expanded cellular silicone rubber has a predominantly closed cell structure with an integral smooth surface skin, leading to very low water absorption. It has excellent thermal insulation properties and is also a good acoustic insulation material at the temperature extremes where thermoplastic foams cannot be used. It is an ideal insulation material for high temperature tubes, pipes and hoses. SS grades are suitable for long term continuous use from -60F (-50C) to 400F (204C) and for intermittent use from -80F (-62C) to 450F (232C).
