TPEs

  • TPE has higher elongation in normal temperature, and plasticization in high temperature, and yet these are reversible because these change cause without crosslinking reaction.
  • TPE is alloy of two types contents; one is soft-segment that has Elastomer elongation in its numerator structure, and the other is hard segment to restrict molecular to avoid plastic deformation.
  • This hard segment plasticizes by heating to be easier to molding and cured by cooling, so it is recyclable.
