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.

Due to the strong polarity of the PVC molecular chain, usually it needs higher processing temperature, and need to add plasticizers to reduce its intermolecular gravitational force, and thus increase the flexibility of the products.

TPU is short for Thermoplastic Urethane. It is a polymer material made of diisocyanate molecule,s such as diphenylmethane diisocyanate (MDI) or toluene diisocyanate (TDI), and macromolecular polyols and low molecular polyols (chain extender) reacted and polymerized together.

UV absorber is a widely used and well-known class of light stabilizers, according to its structure can be divided into Salicylate esters, Benzophenone, Benzotriazole, Triazines, etc., And quenching agent is mainly some bivalent organic nickel chelate, its organic part is substituted phenol and thiobisphenol.

OMNISTAB®UV1 is a high-efficiency liquid methimazole UV absorber, which can effectively absorb ultraviolet light from 240 to 330 nm, and almost completely absorb it in the band of 300 to 330 nm.

Polyurethane soft foam, commonly known as polyurethane sponge or foam, is a flexible material with a certain level of elasticity.
