Room Temperature Casting Cold Cast Polyurethane
1. Introduction
Cold cast polyurethane is widely used in flexible polyurethane resin or foam to rigid plastic. These systems are formulated for use at room temperature and do not require heating for post-curing, so production is simple and fast. Both low-pressure and high-pressure mixing equipment are suitable, and many products can be mixed manually or by machine. These elastic polyurethanes are commonly used in concrete molds, building molding machines, filtering devices, etc.
