UV light resistance

The most commonly used stabilizers are barium, cadmium, zinc, calcium and cobalt salts of stearic acid phosphorous acid esters epoxy compounds and phenol derivatives. Using stabilizers can improve the heat and UV light resistance of the polymer blends, but these are only two aspects. The processing temperature, time, and the blending equipment also have effects on the stability of the products. The same raw materials and compositions with different blending methods resulted in products with different heat stabilities. Therefore, a thorough search for the optimal processing conditions must be done in conjunction with a search for the best composition to get the best results. [Pg.140]

PVC modified by TPU has improved abrasive resistance, improved impact resistance (especially at low temperatures), improved oil resistance, improved heat and UV light resistance, and improved adhesive capability with other materials. [Pg.143]

Purified elastin has a pale yellow color and a bluish fluorescence in uv light. Resists acid and alkaline hydrolysis. Practically insol in a wide range of hydrogen-bond-breaking solvents at temps up to 100° and swells, but does uot dissolve, in phenolic solvents. It appears practically impossible to bring elastin into oln except by hydrolytic reagents capable of rupturing peptide bonds. Elastin is one of only a few polymeric substances which, in the presence of water, exist in a form with rubber-Like extensibility and low modulus of elasticity. Enzymes which dissolve fibers of the insol protein... [Pg.553]

The material for the lens material must comply with the European standard EN 166 [6-55]. This standard defines minimum quality requirements for optical, thermal, and mechanical properties as well as UV light resistance. According to it, the lenses must be free of any material defects, like blisters, opacity, cords, or inclu-... [Pg.208]

When formulated with a HALS additive, better UV light resistance than a phenol/HALS system. [Pg.46]
