The role of modified plastics in the automotive industry is becoming more and more obvious. Most of the interior and exterior parts of automobiles are made of modified plastics.
PP, ABS, PA, PC, POM, PBT, PRT, PVC and other plastics are widely used in automobiles. Among all automotive plastics, PP has the highest share, with PP accounting for 37 percent , followed by PA with 17.3 percent and ABS resin with 12.3 percent
Because PP, TPU, and ABS account for more than 50 percent of the total, and because the pendant methyl group in the PP structure and the unsaturated double bond in the ABS structure cause the material itself to age more easily than other modified plastics, the car is modified The stabilization of materials is mainly carried out around these three materials. It can shield or absorb the energy of ultraviolet rays, quench singlet oxygen and decompose hydroperoxide into inactive substances, so that high molecular polymers can eliminate or slow down the possibility of photochemical reaction, prevent or delay under the radiation of light The process of light aging, so as to achieve the purpose of extending the service life of high molecular polymer products.
In order to better protect cars in the hot summer, stabilizers are essential sunscreens in the automotive industry
