    Introduction

    "PTMG+MDI" is MDI terminated polyether base PU prepolymer. This polyurethane prepolymer is for casting polyurethane elastomer use. 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.
