SSP391 is an 80-durometer (Shore A) heat-cured silicone elastomer that uses a Varox-peroxide and dicumyl-peroxide catalyst system. This silicone compound meets the requirements of the A-A-59588, Class 2A and Class 2B, Grade 80 specification. Because A-A-59588 compounds require significant testing, there is a $500 minimum order amount. Small-quantity orders may be subject to certification charges.
SSP391 elastomers have been tested to meet the physical and mechanical properties for A-A-59588, Class 2A and 2B, Grade 80 silicones. The A-A-59588 standard supersedes the ZZ-R-765 specification and meets the SAE-AMS-3305 standard for general-purpose, 80-durometer silicone rubber. As A-A-59588 Class 2A and 2B silicones, SSP-391 elastomers provide high-temperature resistance and low compression set.
SSP391 silicone elastomers are peroxide-cured, a robust technique that is also cost-effective. Because peroxide cure silicones aren’t inhibited by amines, tin compounds, latex, or urethanes, these compounds are often used in industrial applications such as aerospace and automotive. To prevent bloom and promote compatibility with food and healthcare requirements, SSP post-bakes all peroxide-cured silicones.
SSP391 silicone elastomers are supplied as ready-to-mold compounds or compression-molded sheet stock. These silicone compounds can be pigmented to meet your application requirements, but the most popular colors produced are red and black.
Download the SSP391 data sheet for specifications such as tensile strength, elongation percentage, tear resistance, specific gravity, and cure profile. MSDS information is available, and SSP can supply data from additional tests (such as compression set) performed in accordance with A-A 59588, Class 2A and Class 2B, Grade 80 requirements.
