Description:

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.

Performance:

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.

Compound:

Fully vulcanized EPDM rubber particle in a thermoplastic matrix of Polypropylene (PP).   Santoprene? thermoplastic rubber grades are proprietary products.

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).

Applications:

Appliance Components, Automotive Applications, Automotive Under the Hood, Consumer Applications, Diaphrams, Electrical Parts, Gaskets, Seals.

Recyclability:

Santoprene is polyolefin based and completely recyclable.
