State-of-the-art capabilities in silicone The popularity of silicone has led to Apple Rubber's development of precision mold capabilities. Even the most complex silicone parts and seals can be consistently manufactured using a host of technologies and processes including injection molding and compression molding. We give you all the advantages of silicone...and then some: - Unmatched Temperature Resistance -- withstands temperature extremes from -75°F to 600°F. - Excellent Mechanical Properties -- high tear and tensile strength, good elongation, excellent flexibility and a durometer range of 10-80 Shore A. - Superior Insulating Properties -- exceeds all elastomers in its insulating properties making it ideal for electrical applications. It is non-conductive and maintains dielectric strength in high and low temperature extremes. However, conductive silicone compounds are available if required (for EMI shielding). - Exceptional Weather Resistance -- resists the damaging effects of UV light, ozone, O2, weather, moisture and steam with outstanding aging characteristics. - Good Chemical Resistance -- resists water and many chemicals such as some acids, oxidizing chemicals, ammonia and isopropyl alcohol. Note: concentrated acids, alkalines and solvents should not be used with silicone rubber. - Excellent Dimensional Stability -- offers excellent accuracy and provides versatility of shape and form to many seals and parts, even intricate shapes.
