CLS 5000 is a fast-curing, high tear strength liquid silicone rubber offering primerless adhesion to a variety of thermoplastic and metal substrates and is an excellent candidate to consider for insert and over-molding applications.  A nickel Teflon coating should be applied to the mold to help with part release from the tool.

Key Features and Typical Benefits:

  • Biocompatibility (USP Class VI, ISO 10993)
  • Primerless adhesion to nylon and co-polyesters, polybutylene terephthalates (PBT), stainless steel and aluminum
  • Adhesion to polysulfone after plasma activation of the substrate
  • High thermal stability
  • Easily pigmentable with LSR color pastes

Potential Applications:

  • Membranes and diaphragms
  • Surgical and dental instrument grips
  • IV components
  • Other hard-soft combinations
