Polycarbonate(PC), is a comprehensive engineering plastic with good performance, also known as transparent metal.PC has good impact strength and mechanical properties

Polyurethane is mainly divided into molded flexible foam, block flexible foam, rigid foam, thermoplastic polyurethane elastomers(TPU), etc..

Polyurethane is an important polymer material, and its excellent physical and chemical properties are widely used in industry and daily life.

Moderate sun exposure is beneficial to human health and promotes vitamin D synthesis. However, sunlight is energetic, and prolonged exposure to the sun or lack of attention to sun protection can lead to many skin problems, such as causing sun spots and hyperpigmentation.

Automotive primers have gone through several major changes such as oil-based primer, nitro primer, alkyd resin primer

Nylon engineering plastics(Abbreviation is PA), refers to the main chain of the molecule contains repeated amide groups(-NHCO-) thermoplastic resin general term.

UV 326 is kind of benzotriazole UV absorber with the dual function of light stabilizer and antioxidant. It can absorb 270-380nm of UV light, with a peak absorption of 353nm.

Phosphite antioxidants are the backbone of auxiliary antioxidants, which can convert hydroperoxide ROOH into radical-free, unreactive and thermally stable product.

Acrylonitrile-butadiene-styrene (ABS) copolymer has both the rigidity of acrylonitrile, the toughness of butadiene and the easy processing properties of styrene.
