Lightweighting Materials: Santoprene TPV

Thermoplastic vulcanizates (TPV) are high-performance elastomers that combine the performance characteristics of rubber and plastics. TPV’s are part of the thermoplastic elastomer (TPE) family of polymers. TPV compounds offer flexibility, durability, and ease of processing. For these reasons, TPV’s can be used to fashion sealing solutions for a variety of applications, including those in the general industrial, automotive, electrical and electronics, healthcare, consumer products, and building and construction market segments.

About Santoprene TPV

Santoprene™ is a well-known TPV. Santoprene™ comprises polypropylene, EPDM rubber, and other ingredients into a compound which can be used to produce flexible engineered parts for a variety of uses. Santoprene™ has the look and feel of EPDM rubber, but offers significantly lower weight. Parts made from Santoprene™ can weigh up to 30 percent less than their EPDM counterparts. This makes Santoprene™ an attractive choice for parts production that can assist in the “lightweighting” of vehicles.

Santoprene TPV provides excellent sealing properties and chemical and temperature resistance. A wide variety of grades are available, ranging from a hardness of 35 Shore A up to 50 Shore D. Santoprene™ contributes to environmental sustainability by being fully recyclable within the manufacturing process.

Santoprene™ for Vehicle Lightweighting

In the automotive industry, vehicle lightweighting has assumed heightened importance as automakers strive to build cars that are less heavy and more fuel efficient. A key element of lightweighting is replacing parts traditionally made from metal and replacing them with parts made from advanced composite materials such as Santoprene™.
