WESTON™ TPP
WESTON™ TPP phosphite ester is a versatile aryl phosphite which can be used as a stabilizer in many types of polymers including: adhesives, styrenics, engineering thermoplastics, polyesters (to regulate viscosity and improve color stability), polyolefins (as a catalyst adjuvant), polyurethanes (to prevent scorching during curing and improve color stability), coatings, epoxies, and PVC where regulatory approval for food contact is not required.
