How To Choose Plastic Stabilizer (Antioxidant | UV Absorber | HALS)?
A Selection Guide of Plastic Stabilizers
General Selection Guild of Antioxidants for Use With UV Absorber
Care is needed in selecting antioxidants for use in combination with effective light-stabilization systems. High molecular weight stabilizers provide high levels of heat stability at normal application temperature. To avoid color shifts (especially yellow discoloration), BHT-free resins should be used with HALS formulations. Sulphur-containing organic compounds used as thio-synergists are known to reduce the light stability level conferred by HALS, and high levels should be avoided.
