Polypropylene is commonly used as an antioxygenate
The antioxygenation of phosphatide includes 3 aspects: hydrogen peroxide decomposition agent, metal inactivation agent, and the fading agent of quinone compounds.
The phosphoric acid ester reacts with hydrogen peroxide to generate oxidative stable phosphate, which not only stops the chain transmission of oxidation reaction, but also improves the stability of the polypropylene to the light. Polypropylene common phosphite antioxidants and polypropylene, residual metal catalyst component in the metal ions lose activity, reduce the production of peroxides and hydrogen peroxide in the polymer.
In the use of hindered phenolic antioxidants such as butylated hydroxytoluene, and peroxide reaction quinone or methyl quinone compounds, its product is yellow, the results make the polymer to become yellow, but after joining phosphite antioxidants and quinones or methyl quinone compounds, generates colorless aromatic phosphate ester, phenolic antioxidants and phosphite antioxidants and can improve the color stability of polypropylene.
Polypropylene common phosphite antioxidants are mainly phosphite nonyl phenyl ester (TNP), two phosphite (18) alkyl pentaerythritol ester (618), phosphite (2, 4 - tert-butyl phenyl) ester (168), two phosphite double (2, 4-2 tertiary butyl phenyl) pentaerythritol ester (624), etc.
Polypropylene in common phosphite ester antioxidant 168 is commonly used auxiliary antioxidant treatment, and 618 it has good heat resistance, high effective phosphorus content, the decomposition of hydrogen peroxide ability, etc. In giving products processing stability, heat stability, good colour and lustre and lasting weatherability is outstanding, has been widely used in polypropylene, and in order to improve the hydrolytic stability, also joined the mass fraction of 1% three isopropanolamine, developed a corresponding antioxidant 619, fang heartland of phosphate ester antioxidant (P - EPQ) processing stability effect is better than antioxidant 168, but because the price is expensive, to improve the colour and lustre is limited to certain purposes.
A series of solid phosphatates (624, 626, PEP-36) are used for polypropylene, which makes the preparation of stabilizers simple and the operation cost is reduced.
The tri-nonyl phenyl phosphite is a chemical substance. The molecular formula is C45H69O3P, the molecular weight is 689.0, and the phosphorus content is 3.8.
Triphenyl phosphite (antioxidant, stabilizer TPPi)
Packing method: net weight of 200KG/galvanized iron bucket (a small cabinet to hold 16 tons), 1000KG/IB (a small container with 18 tons) or 23 tons of it.
Port of shipment: Shanghai port
Price quotation validity: 15 days
Warehouse time: within 15 days (customs clearance)
Export rights: our own right to import and export.
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.
The tri-nonyl phenyl ester (TNPP) is a non-polluting heat-resistant antioxidant. Phosphite nonyl phenyl ester is suitable for the SBS, TPR, IPS, PS, SBR, BR, PVC, PE, PP, ABS, such as rubber elastomer, hot oxygen high efficiency, stable processing in use process, phosphite nonyl phenyl ester is especially suitable for discoloration stabilizer. It has no influence on product color, and the tri-nonyl phosphite is widely used in white and bright color products. It can improve the heat resistance and oxidation resistance of rubber products and prevent resination in polymer manufacturing and storage. Inhibition of gel generation and viscosity increase, tri-nonylphenyl phosphite.
Antioxidant 618, also known as ap-618, pentaerythritol diphosphite, pentaerythritol distearate distearate, white waxy - like solid. Due to the structure of pentaerythritol and high molecular weight features, can be used with hindered phenolic antioxidants in the high temperature processing polymeric material applications, as the high temperature antioxidants used in polyethylene, polypropylene, polyester and PVC, etc.
Used for high temperature antioxidant, often used with hindered phenolic antioxidant, used for ABS, PS, HIPS, NBR, SBS, PP, PE, LLDPE, PVC, PC, PA, PET, the UP, polyamide fiber, polyester fiber, adhesives, coatings, printing ink, compound YongZhuJi production and processing, calcium zinc stabilizer distribution, etc.
Because of the structure of diphosphatate, alkyl trivalent phosphorus content is high, which makes the effect of anti-oxygen more prominent and efficient. And approved by the multinational about food and health institutions, can be used for food packaging materials (TITLE21 CFR. 178.2010), because do not contain alkyl phenol in the structure, in accordance with the latest market laws and regulations and the development tendency, and uv absorber and better.
Antioxidant 168 is a kind of excellent phosphite antioxidants, its extraction resistance is strong, the hydrolysis stability, and can improve the light stability of the products, can be used in combination with a variety of phenolic antioxidants. Cyanox2777 is a compound of 1790 antioxygenated 168 and phenolic antioxidants. Will phosphite ester used with phenolic antioxidants compound, can give full play to the synergistic effect, composition of phosphite as auxiliary antioxidant, cannot have long-term and stable effect, but with of hindered phenol compound, has obtained the good effect of compound, can be used for a variety of polymer.
Auxiliary antioxidants, and the main antioxidant of zm - 1010 or 1076 compound, has good synergistic effect, can effectively prevent the thermal degradation of polypropylene, polyethylene in basic injection, additional long-term protection to polymer.
This product is not colorless, non-polluting and volatile. Used for polyethylene, polypropylene, polystyrene, polyester and polyamide products. It is widely used in polymer materials such as polyolefins, styrene monomers and copolymers, elastomers, adhesives, engineering plastics (e.g. PE, PP, PVC, PS, polyamide, polycarbonate, ABS) etc.
