Santoprene™ TPV for low-temperature performance in refrigerator seals and gaskets
Santoprene thermoplastic vulcanizates (TPV) combine low compression set and excellent elastic recovery at low temperatures, making them ideal for refrigerator components, including:

  • Extruded or molded freezer interior gaskets
  • Cold air transfer ducts
  • Water dispenser and filter gaskets
  • Drain tubes and seals
  • Motor mounts and vibration dampeners

Parts consolidation 
Bonding properties with polypropylene (PP) and engineered plastics such as polyamide and ABS help create excellent refrigerator seals. Santoprene TPV can also reduce manufacturing costs by decreasing cycle time and assembly steps compared with thermoset rubber.

Design freedom 
The colorability, tight molding tolerances and compatibility of Santoprene TPV with other materials, including our ExxonMobil™ PP resins, support the design of cost-efficient components that are in step with latest market trends. Overmolded connectors for cold air transfer ducts are just one example.

UL, NSF, FDA and RoHS certification 
Santoprene TPV grades recommended for refrigerators, including NSF- and FDA-approved grades, are fully UL- and RoHS-compliant. This helps you get products to market faster.

Consider other polymer solutions from ExxonMobil Chemical
Vistamaxx™ propylene-based elastomer (PBE)  provides excellent clarity when added as a cold-temperature impact modifier to polypropylene and, with inherent outstanding adhesive strength, protects finished product surfaces when co-extruded as a surface protective film.
