Santoprene rubber is mixture of vulcanized EPDM rubber and polypropylene. It is a fantastic choice of synthetic rubber material to use for any application that sees a high working temperature range. This thermoplastic rubber is ideal for use in various automotive and electrical projects thanks to its ability to operate in temperatures reaching up to 300° F. It is safe for outdoor use thanks to its resistance to ozone and UV rays. The Santoprene elastomer is also very durable and flexible, with a mid-level durometer rating of 55-65. This particular type of Santoprene sheet rubber comes with a unique block surface design.
Block-Patterned Surface Texture: The distinguishing feature about this Santoprene rubber sheet is its surface texture. Unlike the standard smooth surface texture of most other elastomers, this sheet of thermoplastic rubber is manufactured with a block surface pattern. All across its body are tiny blocks. These mainly serve an aesthetic function for application where appearances are important. However, they do provide for a better level of grip so as to reduce the chances of it slipping out of place.
EPDM Benefits: This thermoplastic rubber is made partly from fully vulcanized EPDM rubber. The EPDM elastomer is known for being a good rubber material to use in outdoor settings. As a result, its outdoor weathering resistance traits are passed on to Santoprene rubber. A Santoprene sheet can operate comfortably in the outdoors because it features superior longevity in the face of UV rays and ozone. Outdoor elements like UV rays can damage other elastomers by causing cracks to form on their surfaces, but that is not the case with the Santoprene elastomer.
Excellent Temperature Range: Silicone often tends to be the first rubber that comes to mind when people are looking for a high-temp elastomer. However, Santoprene rubber should also be considered. This synthetic rubber material has an excellent working temperature range. It can endure temperatures that go as low as -74° F and can equally function in conditions that reach as high as 300° F. This excellent feature allows the rubber to be used in various temperature intensive applications in the automotive, electrical, and industrial fields.

Santoprene thermoplastic rubber is a family of high-performance elastomers which combine the performance characteristics of vulcanized rubber, such as flexibility and low compression set, with the processing ease of thermoplastics. It is the mixture of in-situ cross linking of EPDM rubber and polypropylene.
Withstands transient temperatures up to 150 Celsius (300F) and continuous temperatures to 135 Celsius (275F) per SAE J2236 (Standard Method for Determining Continuous Upper Temperature Resistance of Elastomers).
Fluid resistance similar to polychloroprene for aqueous-based fluids, oils and hydrocarbons.
Low compression and tension set.
Outstanding dynamic fatigue resistance.
Excellent ozone and good weathering resistance.

Bonding and Decorating:
Santoprene TPV’s, like other polyolefins (PP, PE) are difficult materials for bonding and decorating. In order for an adhesive to wet Santoprene, it must have a critical surface tension lower than 28 dyne/cm. Most adhesives, tapes and coating have surface tension above this range and do not wet (adhere to) solid Santoprene TPV. For more information view document TL00308 (Exxon Mobil).
