Washing machines

Santoprene™ TPV provides excellent performance in washing machines
Santoprene thermoplastic vulcanizates (TPV) combine low compression set, elastic recovery and outstanding chemical resistance, making them ideal for home washing machine components, including:

  • Top-load washer door seals
  • Filter seals
  • Hoses and couplings
  • Vibration dampeners
  • Molded cuffs and elbows

Durable and reliable 
Designed specifically for appliance applications, Santoprene W255 TPV facilitates washing machine durability and reliability. They combine excellent mechanical properties with protection against heavy concentrations of detergents, bleach, high heat and moisture. See the online fluid resistance guide.

Parts consolidation 
Bonding properties with polypropylene (PP) and engineered plastics such as polyamide or ABS help deliver excellent sealing performance and manufacturing efficiency. Overmolding Santoprene TPV onto a PP frame, for example, produces a strong top loader door seal with excellent sealing characteristics and good heat resistance at a low per-unit price.

Design freedom 
The colorability, tight molding tolerances and compatibility of Santoprene TPV with other materials support the design of cost-efficient, brand-differentiating solutions. Create color-matched seals or soft-touch controls.

UL, NSF and RoHS certification 
Santoprene TPV recommended for clothes washers, including NSF-approved grades, are UL- and RoHS-compliant, helping you get products to market faster.
