Title:Silicone Rubber, Extreme Low-Temperature Resistant, 15 - 30
Issuing Committee:Ams Ce Elastomers Committee
Scope:This specification covers an extreme low-temperature-resistant silicone rubber in the form of sheet, strip, and molded shapes.Primarily for rubber-like parts required to operate or seal from -112 to +446 掳F (-80 to +230 掳C), compounded especially for operation at extreme low temperatures. Silicone rubber is resistant to deterioration by weathering and by high-aniline-point petroleum-base oils and remains flexible over the temperature range noted. These products are not normally suitable for use in contact with low-aniline-point petroleum-base fluids, including fuels, due to excessive swelling.【英文标准名称】:StandardGuideforSpectrometricAnalysisofReactiveandRefractoryMetals
