Heat stabilizers Help prevent thermo-oxidative breakdown of polymer to help maintain color and other physical properties.
Heat stabilizers/nucleators Increase thermo-oxidative stability and nucleate the polymer for faster crystallization rates.
Impact modifier concentrates Improve impact strength of polyesters.
Melt strength enhancers Build melt strength.
Mold/roll releasers Reduce sticking to molds and rolls
Slips Improve coefficient of friction without affecting clarity.
Ultraviolet screens Protect package contents from ultraviolet light.
