Liquid Silicone Rubber


As the HCR (High Consistency Rubber), the liquid silicone rubbers belongs to the HTV (High Temperature Vulcanisation) family. Among others, the most interesting feature is its excellent processability.

Liquid silicones have special characteristics in comparison with rubbers and other elastomers:

  • an excellent processability (the raw material is ready to use)
  • short cycle time (Platinum catalyse curing)
  • great resistance to temperatures (- 40°C to 250°C)
  • excellent chemical resistance
  • resistance to ageing (UV, ozone)
  • biocompatibility
  • No propagation of flame (UL94V0)
  • Good behaviour to sterilization (vapour, gamma, ETO)
