UIP Polyimide powder

UBE provides polyimide powders which have excellent heat-resistance
and excellent chemical resistance.

UIP Products and Features

UIP is an excellent heat-resistant polyimide powder, based on Biphenyl tetracarboxilic dianhydride (BPDA) originally developed by UBE.

UIP products

  1. UIP-RHeat-resistance, high-impact ability, easy forming
  2. UIP-SSuper heat-resistance, low creep, low water absorption, high modulus, high ablation resistance
  3. UIP-SASuper heat-resistance, low creep, low water absorption, easy forming
  4. Common characteristic of UIP :
    High chemical resistance, high radiation/plasma resistance, flame retardance

Application example

  • Raw material of polyimide shape
  • Binder for diamond grindstone
  • Compound for
    PTFE, Fluorocarbon elastomer,
    Phenolic resins
