UIP® Products and Features
UIP® is an excellent heat-resistant polyimide powder, based on Biphenyl tetracarboxilic dianhydride (BPDA) originally developed by UBE.
UIP® products
UIP®-R Heat-resistance, high-impact ability, easy forming
UIP®-S Super heat-resistance, low creep, low water absorption, high modulus, high ablation resistance
UIP®-SA Super heat-resistance, low creep, low water absorption, easy forming
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
