Is It A Problem Of Pigment, Masterbatch, Modification Or Molding That Causes The Color Of Plastic Products To Change Secretly?

(1) During high-temperature molding, the oxidation degradation of the matrix resin may cause color change;

(2) Fading of colorants at high temperatures can cause discoloration of plastic products;

(3) The chemical reaction between coloring agents and matrix resins or additives will cause color change;

(4) The reaction between additives and the automatic oxidation of additives will cause color changes;

(5) The isomerization of coloring pigments under the action of light and heat can cause color changes in the product;
