Plastic auxiliary antioxidant
Phosphite nonyl phenyl for plastic auxiliary antioxidant, can prevent from polymer heat, sunlight and oxidation and degradation and keep the thermal stability of the polymer processing, and phenolic antioxidants with enhanced antioxidant capacity.
Phosphite nonyl phenyl acetate as representative products, plastic auxiliary antioxidant low toxicity, no pollution, is a natural rubber latex and styrene butadiene rubber latex and nitrile rubber latex, butyl latex, such as polyethylene, polypropylene FVC of antioxidant and the gelling agent, general antioxidants used in rubber, especially in the styrene butadiene rubber, butadiene rubber tire stock is given priority to, with outstanding thermal oxidation resistance and resistance to fatigue cracking, and phenols or amine, and can effectively enhance the antioxidant capacity.
ODP (phosphite diphenyl - dioctyl) for alkyl aryl phosphite, typical products of phosphate ester antioxidant efficiency and hydrolysis resistance is better than that of Triphenyl phosphite, for polyolefin, especially for polypropylene (PP), and phenol antioxidant and can obviously improve the PP of discoloration and embrittlement. In PVC, with the metal soap stabilizer and can improve the color and weatherability of the products. ODP can also be used to synthesize the anti-pollution plasticizer and stabilizer of butadiene rubber.
Tri-nonyl phosphite is characterized by high phosphorus content and high antioxidant capacity. The thermal stability can be maximized when used with the antioxidant 1010. The modified product was made by adding a trace waterproof solution in the tri-nonphenyl phosphite, and it was placed in the relative humidity for 4 hours, and only increased by 1%. The two products already occupy 70 percent of the U.S. antioxidant market and 40 percent in Europe.
The research of synergistic mechanism and the development of synergistic component are the key to the development of additive compound technology in the future.
On some existing varieties, in view of the deficiencies in chemical structure improvements, such as the phosphate ester machining stability is good, but is sensitive to water, easy to hydrolysis, available amine to reduce also can improve the molecular weight of phosphite ester hydrolysis sensitivity to reduce volatile, precipitation resistance and durability.
Polymer in the process of storage, forming and use, due to the pressure, shear force, heat, and the role of oxygen, often changing structure, gradually lost the use value, its performance for the physical and mechanical performance degradation, melt flow rate change, color appearance change, etc.
Triphenyl phosphite (TPPi antioxidants, stabilizer) is mainly used in PVC, polyethylene, polypropylene, polystyrene, polyester, abs resin, epoxy resin, synthetic rubber antioxidant stabilizer, used in polyvinyl chloride (PVC) products as a chelating agent.
Cas no. : 101-02-0
HS: 29209019.00
The most important index of products: colorless, yellow liquid
Density (rho) 2525:1.183-1.192, refractive index (eta 020) : 1.585 1.590, freezing point ° C: 19-24, chloride (Cl - %) : 0.20 or less
Tax refund: the current tax refund of Triphenyl phosphite is 9 percent
Raw materials: phenol, phosphorus trichloride, phosphorus trichloride.
In order to prolong the life of polymer materials, inhibit or delay the oxidation degradation of polymer, the polymer processing and meet the requirements of more and more high, phosphite ester antioxidant compounds as hydrogen peroxide decomposition agent and free radical catching agent, can well meet the requirements of these aspects, obtained the fast development. It is also permitted in Canada, Japan, Europe and many other countries to use as a plastic auxiliary antioxidant for many of the polymers used in food contact.
Alkyl pentaerythritol diphosphatate (SPEP) is one of the family members of pentaerythritol phosphatesters, and is the antioxygenation agent of phosphoesters. It is mainly used as auxiliary antioxidant for polyethylene, polypropylene, PVC, ABS resin, polyester and other synthetic resin. Because of the high temperature volatility, the processing stability is good, the heat resistance performance is excellent, and the product is transparent, not polluted, with the ultraviolet absorbent and with the synergistic effect.
The antioxides and sulfur-containing antioxidants are auxiliary antioxidants. At home, the production and consumption of the antioxygenation agent of phosphatate are about 30% of the total amount of domestic antioxidants. It can effectively improve the thermal oxidation resistance of plastic materials and maintain a good appearance of plastic products.
The newly developed phosphatide is a modified version of the existing variety, aiming to reduce hydrolysis sensitivity while maintaining the processing performance. It is well known that amines can reduce the hydrolysis sensitivity of organic phosphatides, and many industrial phosphates are used to stabilize them. For PS-2, the amine functional group binds to the phosphatate molecules, and the hydrolytic stability has reached an unprecedented level. At the same time, the processing performance has no loss. In addition to polyolefins, it can also be used in engineering plastics such as polyamide and polyester.
Phosphite as auxiliary antioxidant has outstanding thermal oxidation resistance and the fatigue cracking resistance, used for auxiliary antioxidant, can prevent because of polymer is heated, illumination and oxidation degradation and thermal stability, maintain polymer with phenolic antioxidants with enhanced antioxidant capacity. The polycyclic structure of phosphite also has hydrolysis resistance.
