List of Polyether (PTMEG) Base High Performance Casting Systems

Solid/Non-Foam Casting Resins

Polyether (PTMEG) base high-performance polyurethanes are known for their "high-energy" characteristics, which include high-rebound, excellent abrasion resistance, and high elongation. Together with their excellent tensile and cut/tear resistance properties, parts molded with these materials are preferred in a variety of applications including inline skate wheels, sizing screens for mined products such as rocks/sand/minerals, material handling parts, and other highly demanding applications. These materials are also known for excellent water resistance and are recommended for long-term use in constant aqueous environments.

For applications require high cut/tear resistance, oil resistance, low rebound, please consider our polyester base polyurethane casting systems

 

Ether "Quasi" Systems

These are systems consist of a MDI/Ester prepolymer at higher %NCO (15 - 26 %) cured with our special curatives. "Quasi" systems are known for low viscosity and relatively lower processing temperature.

Ether "Full-Prepolymer" Systems

 

These are conventional prepolymer systems consists of MDI/Ester prepolymers at lower %NCO (less than 15 %), can be cured with 1,4-Butanediol, other standard amine/polyol urethane curatives, or our special curing agents. These are also commonly called "hot-cast" urethane systems.
