ESS4772 Ultra-Thin Platinum Cured Silicone Now Available

3 sheets with samples of ESS4722 platinum catalyzed HCR solid siliconeIn an effort to have readily available inventory of high performance ultra-thin silicone, Stockwell Elastomerics has developed a new product family to satisfy the demands of the advanced and emerging technology sector. The ESS4722 product family is an ultra-thin, platinum cured, solid silicone that is available in thicknesses ranging from 0.010” to 0.125”. This material is immediately available in 20A, 30A, and 40A durometer to satisfy the needs of low closure force applications. For identification and functional purposes, this material is available in black, off-white, and translucent. The high purity platinum catalyst delivers an exceptional ultra-thin material option for applications sensitive to volatile compounds.


ESS4722 – High Purity, Ultra-Thin High, Consistency Silicone Rubber
PDF# Material Color Durometer Base / Cure Description
540 ESS4722 Black 20 LSR / Platinum High Consistency Rubber (HCR), 36″ wide continuous rolls, low closure force
Off White 30 LSR / Platinum High Consistency Rubber (HCR), 36″ wide continuous rolls, low closure force
Translucent 40 LSR / Platinum High Consistency Rubber (HCR), 36″ wide continuous rolls

The ESS4722 solid silicone allows for IP67 level sealing capability when implemented with a well-designed housing. As a result of ESS4722’s excellent compression set resistance and its capability to withstand strenuous environmental conditions, enclosures with ESS4722 sealing can expect consistent and reliable results over the lifetime of the product.
