Weather resistance of PVC profiles and pipes

PVC resin has a number of double bonds and unstable structure, which is easy to break under the damage of light and oxygen, which causes discoloration of the product. The unstable structure of different resins is not the same, that is, the stability is not the same, so choose A resin excellent in stability and weather resistance is a prerequisite for maintaining the weather resistance of the product.

Reasons and solutions for yellowing of pvc profiles

In the production of pvc profile and its application, thermal photooxidation reaction will occur. The polymer macromolecule will be oxidized by trace moisture, acid, alkali and other impurities under the action of heat and pressure, and the molecular weight will decrease. Molecular structure changes. This chemical change is called degradation, and the most intuitive performance is that the surface is yellowed, the gloss gradually disappears, and even the gray is changed. The discoloration of the profile causes the customer to have doubts about the performance of the PVC material, and the consequences are serious.
