High Strength 1:1 Two-Component Polyurethane Liquid Rubber For Making Wall Tile Concrete Stamping Molds
Description
Polyurethane liquid rubber consists of A&B component, B is curing agent, and A is polyurethane prepolymer.
can be used as a concrete or cement stamping mold as well as for making hard durable rubber parts for machinery or automotive applications.
There are many different formulations of polyurethane rubbers for mould making. The polyurethane casting rubber can be pure or filled with special mineral charges. Are available different hardness from 40 Shore A to 80 or 90 Shore A.
Applications
Substitute for making the mould of “cultural stone” and concrete stamping. It also applies to electrical equipment potting, rubber rollers, Ski and snowboard ,rubber plates, rubber wheels, shoe models and others.
