The protective umbrella of automobile ultraviolet absorber

In the automotive industry, the role and status of modified plastics are more and more obvious. Most of the automotive interior and exterior parts are made of modified plastics.

 

PP, ABS, PA, PC, POM, PBT, PRT, PVC and other plastics are widely used in automobiles. Among all the automotive plastics, PP accounts for the highest proportion, with PP accounting for 37%, followed by PA accounting for 17.3% and ABS resin accounting for 12.3%.

 

Because PP, PA and ABS account for more than 50% of the total, and because of the unsaturated double bond in the side methyl group of PP structure and ABS structure, the material itself is more prone to aging than other modified plastics, so the stabilization treatment of automobile modified materials mainly focuses on these three materials. It can shield or absorb the energy of ultraviolet ray, quench singlet oxygen and decompose hydroperoxide into inactive substances, so that the possibility of photochemical reaction can be eliminated or slowed down under light radiation, and the process of photoaging can be prevented or delayed, so as to prolong the service life of polymer products.

 

In order to get better protection in the hot summer, ultraviolet absorber is an essential sunscreen in the automotive industry.

 

UV absorber 2908

 

Uv2908 has antioxidant activity through free radical capture mechanism in the process of hot processing and mild heating. It can effectively protect the polymer, and has excellent compatibility, low color change, low volatility, low toxicity. It can be used together with phenols, phosphite antioxidants and hindered amine series light stabilizers to improve outdoor weather resistance. The product can effectively eliminate the hydroperoxides in the polymer and has good synergistic effect with light stabilizer and antioxidant

 

Because of its unique properties, it plays an important role in car sunscreen.
