APPLICATION: Primarily for sealing and caulking applications. Elastomeric properties are retained in operation at temperatures from -65 to +450 F (-55 to + 230 C). Silicone rubber is resistant to deterioration by weathering and by high aniline point petroleum base oils@ and remains flexible over the temperature range noted. This material in not normally suitable for use in contact with low aniline point petroleum base fluids@ including fuels@ due to excessive swelling. For mechanical applications where compression set resistance is important@ elevated temperature post-curing of parts may be required.
