Description

Material Notes:
This is a Ester/MDI base high-performance polyurethane casting system. This systems is recommended to applications in which the part requires cut/tear resistance, dry-abrasion resistance, slow response speed, and low energy rebound/response. Ester base systems are generally less expensive than PTMEG base material. Possible applications for this material include skirting for conveyer belts, abrasion resistance liners and parts, and other specialty parts. Unlike conventional full-prepolymer systems, quasi system formulation improves processability, in-mold flow, and components mixing by use of low viscosity prepolymer. This results better physical properties of the products. Can be approved for FDA dry food contact.Information provided by Northstar Polymers.
