Super Resilient Extreme Temperature Silicone Foam
Super Resilient Extreme Temperature Silicone Foam – Stockwell Elastomerics has it! Silicone foam, not to be confused with silicone sponge, is a platinum cured (addition cured) liquid silicone rubber that is expanded. Silicone as an elastomer is very resilient, especially when compared to organic elastomers such as chloroprene. This is attributed to free volume in the molecular make up of silicones that allows the polymer to move more freely making the elastomer more flexible and resilient. This free volume also gives silicones a lower glass transition than organic (carbon backbone) materials, meaning they can naturally perform at lower temperatures without plasticizer. In addition, the Si-O backbone is stronger and less susceptible to breakdown in high temperatures, UV and ozone environments.
Super Resilient Extreme Temperature Silicone Foam is a good description for Rogers Corporations’ HT-800 family of silicone foam products. In addition to being super resilient and having excellent temperature properties, they are formulated in various firmnesses and carry a UL 94V-0 flame rating. HT-800, HT-820 and HT-840 are considered closed cell and are qualified by UL for enclosure gaskets, with UL50 and UL50E recognition.
Below is a list of performance properties for HT-800 silicones… it’s easy to see why these are usually the best gasket materials for indoor and outdoor enclosure gasket applications.
