Excellent sealing properties, durability and chemical and heat resistance make Santoprene thermoplastic vulcanizates (TPVs) lightweight, cost-effective replacements for conventional EPDM and chloroprene rubber materials in demanding under-the-hood air induction systems.

Consolidate parts, eliminate metal fasteners
Santoprene TPVs deliver cost-saving opportunities to consolidate or eliminate parts such as metal fasteners, through a combination of:

  • Excellent bonding properties
  • Suitability for a variety of one- and two-component blow-molding processing
  • Compatibility with polypropylene (PP), polyamide and other thermoplastic substrates 

Resonators and other hard PP-based components often can be welded directly to flexible Santoprene TPV, eliminating the need for clamps or cuffs while providing a rugged, leak-free connection. Low specific gravity (0.97) and designed-in stiffness allow for lightweight parts that resist vacuum collapse.

Durable and efficient
Santoprene™ TPV 101-87 and 103-40/50 grades are suitable for outside and clean air induction applications where durability and -40°C to 135°C (-40°F to 275°F) temperature resistance are essential. Manufacturers gain design freedom because components made from TPVs and PP can be created using monolayer or sequential 3-D extrusion blow molding or injection molding. They can also achieve significant cost savings due to shorter cycle times, reduced wall thicknesses and tighter manufacturing tolerances.

Attractive and recyclable
The attractive Santoprene TPV finish complements new under-hood aesthetics. Santoprene TPV offers in-process and end-of-life recyclability.
