Stockwell Elastomerics’ Observations on the RS-700 Series Materials
The RS-700 silicone sponge series has very good mechanical properties, uniform closed cell structure, and a smooth surface as compared to the “fabric” finish on traditional silicone sponge products. The RS-700 series is offered in shades of gray (RS-720 = fog gray, RS-750 = steel gray, RS-770 charcoal gray). As with all silicone offerings, Stockwell Elastomerics is capable of laminating acrylic and silicone pressure sensitive adhesives to the RS-700 series. Lamination bonds are similar to those of the 7000 Series, Bisco silicone foams and Cohrlastic silicone sponge products.

Traditional Silicone Sponge Product Offerings
The RS-700 products look and feel a bit different than traditional silicone sponge products but still possess the same high performance gasket properties: excellent compression set resistance, wide temperature range, UV/ozone resistance and good water sealing. If traditional orange silicone sponge is required, Stockwell Elastomerics still offers Cohrlastic R-10480S and R-10470M silicone sponge products.
