Silicone Elastomers

Silicon elastomers have a distinctive range of properties that distinguish them from other kinds of rubber. Silicone rubber is processed either as ready for use (LSR and HTV) or as solid silicone rubber to which curing agents or additives such as color may be added. The main processing techniques are extrusion, molding (injection molding, transfer), compression molding and calendering.

The most important properties of silicone elastomers compared to other kinds of rubber are:

  • Excellent resistance to high temperatures with simultaneous low-temperature flexibility
  • Extremely low compression set
  • High resistance to chemicals and environmental influences
  • Water-repellent surface
  • Very good mechanical properties over a very wide temperature range with sufficient oil resistance
  • Neutral in taste and odor
  • Biocompatibility
  • Exceptionally high purity
