Santoprene rubber is a unique thermoplastic elastomer that combines flexibility, durability, and a great working temperature range all into one quality synthetic rubber material. The rubber compounds that make up our Santoprene sheets are a mixture of fully vulcanized EPDM rubber and polypropylene. This thermoplastic material features a very good resistance to physical fatigue as well as outdoor environmental factors such as UV rays and ozone. Santoprene is a great sheet rubber material to use for applications that need seals, gaskets, and other various components. It is ideal for use in automotive, electrical, and general consumer products.
A High Performance Elastomer: Santoprene rubber features excellent physical and chemical characteristics. This is a quality synthetic rubber sheet that combines the performance characteristics vulcanized rubber, such as superior flexibility and low compression set, with the processing ease of thermoplastics. This thermoplastic elastomer has a durometer rating of 55-65, meaning that it is able to handle physical indentation fairly well while being flexible and pliable enough to use in various settings.
Great for Automotive Use: One simply has to consider the performance virtues of this thermoplastic material when considering a type of sheet rubber for use in automotive applications. It is already a physically durable material to begin with. However, this high quality synthetic rubber also features other characteristics that make it ideal for the harsh requirements of automotive use. Firstly, Santoprene sheets exhibit a great resistance to the oils and greases commonly found in automotive settings. Secondly, it has the ability to perform in temperatures that go up to 300° F. With these great characteristics, Santoprene rubber is meant for use in the auto industry.
Can Operate in Outdoor Conditions: The Santoprene thermoplastic elastomer is unique in the fact that it can function well in outdoor conditions. UV rays and ozone are a regular presence in the outdoors. They can often damage various other rubber products over time by causing cracks to form on the material surfaces. These Santoprene sheets will not suffer from that problem. This is largely due to the EPDM material used to make them. This quality synthetic rubber can be used in the outdoors fully exposed to UV rays and other weather conditions.

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).
