ExxonMobil Santoprene® 121-67W175 Thermoplastic Elastomer
Categories: Polymer; Thermoplastic; Elastomer, TPE; Thermoplastic Vulcanizate Elastomer (TPV)

Material Notes: A soft, black, UV resistant thermoplastic vulcanizate (TPV) in the thermoplastic elastomer (TPE) family. This material combines good physical properties and chemical resistance, and is designed for thin wall or complex profile extrusion applications. This grade of Santoprene TPV is shear-dependent and can be processed on conventional thermoplastics equipment for extrusion. It is polyolefin based and completely recyclable.

Key Features:

  • Recommended for applications requiring excellent flex fatigue resistance.
  • Excellent ozone resistance.
  • Designed for improved UV resistance.
  • Compliant to EU Directive 2003/11/EC regarding marketing and use of certain dangerous substances and preparations, specifically pentabromodiphenyl ether or octabromodiphenyl ether.
  • Designed for extruding thin sections with excellent definition (down to 0.33 mm [0.013"] radius). Long runs with minimal build-up of material on screen packs or narrow die sections.
  • EU and China RoHS compliant
Applications:
  • Automotive- Interior Mat, Seals, Gaskets and Weather Seals
Uses:
  • Automotive Applications
  • Automotive Exterior Trim
Availability: Africa & Middle East, Europe, North America, Asia Pacific, Latin America and South America
