Polyurethane materials are widely used in various industries, such as plastics, rubber, fibers, adhesives, textiles and thermal insulation materials. MDI is the main aromatic polyisocyanate used in polyurethane industry. However, the polyurethane materials prepared from aromatic isocyanate are prone to yellowing under UV light. Yellowing not only affects the appearance

Ultraviolet absorber is one of the important varieties of polymer additives, according to the chemical structure and mechanism of action, it is divided into Benzophenone, Salicylate, Triazine and benzotriazole and so on. Among them, Benzotriazole uv absorbers have the characteristics of stable chemical property, low toxicity and strong uv absorption!

NENGYUE LS-123 is a new type of hindered amine stabilizer for liquid amino ethers. The product has a low alkalinity and minimizes the reaction with acidic components in the coating. It can effectively improve the life of varnish as well as reduce defects, such as preventing varnish cracking and gloss

Thermoset plastics, which with thermosetting resin as the main component. It’s a kind of plastic that form products by cross-linking and curing with various necessary additives. In the early stage of the manufacturing or molding process, it maintain the liquid, after curing that is insoluble, can not be hot melting or softening again. What

Fluorobenzene is mainly used for the preparation of major raw materials such as the antipsychotic specific drug flucrobutanol, darokutane, trifluoperadinol, trifluoperadinobenzene, pentafluridol, and quinolone drug ciprofloxacin; At the same time, it is also used for the identification of pesticides, egg killers, plastics and resin polymers; Fluorobenzene and γ- The condensation

ABS plastics have excellent processing properties and comprehensive mechanical properties, and are used in automotive interior, home appliance shell, home decoration materials and other fields. However, the unmodified ABS usually has the disadvantage of poor weather resistance. With the extension of service time, the impact strength of ABS plastic will
