The Material

Dicyclopentadiene (DCPD) is a two-component system. The low viscosity liquid is processed using RIM (Reaction Injection Moulding) equipment with a self-cleaning mixing head. DCPD and is injected into a closed mould at low pressure and temperature (mould: 60 / 80 °C). Because of low internal mould pressure compared to injection moulding, the start-up investment for mould (usually aluminium) remains limited and other production equipment can be minimised. Usual cycle times from 6 to 8 minutes. DPCD is self-demoulding without any need for release agents.

 

The benefits of DCPD

  • Polydicylopentadiene – Tough thermoset resin
  • Good dimensional accuracy
  • Unique balance between rigidity and toughness
  • Good paintability to Class A standard
  • Excellent impact resistance
  • Total design/styling freedom, part integration
  • Fast production cycle times
  • Low density (1.03g/cc) ensures excellent weight saving potential
  • Heat resistance
  • Lower tooling costs
  • Variable thickness within the part
  • Properties’ stability over time & weathering
