Two Component Cast Polyurethane Mould Resin For Aircraft Wheel
Chocks
Description
It consists of A&B component, A is polyol, and B is a
MDI-Terminated polyurethane prepolymer.
It has excellent processing properties, solid in common
temperature, shorter gel time, and regulating colours by adding
pigment. The ware has good properties of abrasive resistance,
hydrolysis resistance, transparent, good resilience, stable
dimension.
Application
Substitute for Silicon rubber to make the mould of “cultural
stone”. It also applies to electrical equipment potting, rubber
