Product Introduction

Application
The polyurethane prepolymer is suitable to be used on the following applications: Bushes, Castor Wheels, Couplings, Conveyor Rollers, Cutting Boards, Fork-lift Tyres, Gears, Grading Screens, Pneumatic and Oil Seals, Scrapers, Skate Wheels, Wire Guides.
Introduction
"PU Casting Elastomer" urethane elastomer is polyurethane prepolymer. It can be cured by reacting with a polyamine or a polyol hardener. The molding process is composed of pre-heating, degassing, mixing with a hardener, pouring into the mold, curing, demolding and post curing.
