The main antioxidant of plastic material
Obstructed phenol antioxidant is the main antioxidant of plastic material, which is divided into single phenol, bisphenol, polyphenol and nitrogen heterocyclic polyphenols.
Plastic material of the main antioxidant hindered phenol in single and double phenolic antioxidants, such as butylated hydroxytoluene, 2246, bisphenol A and other products, because of the low molecular weight, volatile and greater mobility, easy to make plastic coloring, in recent years in the plastic consumption greatly reduced.
Plastic material of the main antioxidant polyphenols of hindered phenol antioxidant 1010 and 1076 are the main products of plastics antioxidant at home and abroad, high molecular weight and good compatibility with plastic material, excellent antioxidant effect.
Domestic nitrogen heterocyclic polyphenol antioxidant has a main variety of 3114. It is the highest antioxidant product in domestic production. 3114 products have a certain light stabilizing effect because of the triazine structure in the 3114 molecules. With the improvement of domestic plastic processing technology and level, the amount of 3114 in China has increased obviously.
Bisphenol bisphenol A, 2, 2-pairs (for hydroxyphenyl) propane, is one of the endocrine disruptors (EDCs) in the environment. Flake crystal with a phenol odor. Melting point of 152 ~ 153 ℃, boiling point of 250 ~ 252 ℃ (13 mm hg). Soluble in ethanol, ether, acetone and alkaline water solution.
The acetone and phenol react with the acid. It is a good fungicide and also a raw material for epoxy resin and polycarbonate.
There are various methods of detection. Chromatographic method has been widely used in the actual analysis of samples and has high sensitivity. But its sample pretreatment is cumbersome, the analysis cost is high. However, the biological analysis method, such as immune analysis, has the advantages of simple operation and high selectivity, and it is becoming more and more popular. In addition, due to the secondary tandem mass spectrometry (ms) is lower than other analysis methods of detection limit, therefore, will also become detection of trace concentrations of bpa in environmental and biological samples one of the most promising method.
Polyphenols are compounds found in plant-based foods that are potentially health-promoting. It is found in common plant-based foods such as cocoa beans, popcorn, tea, soy, wine, vegetables and fruits. The ingredients that give chocolate its unique charm are polyphenols. It's a natural ingredient in cocoa beans.
Polyphenols in chocolate are powerful antioxidants. It inhibits LDL cholesterol, the "bad cholesterol" that is "impurities" in the blood. It can lead to atherosclerosis, coronary heart disease and myocardial infarction.
The polyphenols in chocolate can also extend the other antioxidants in the human body, such as the role of vitamin E, vitamin C, and can promote vasodilatation, reduce the inflammatory response and reduce the blood clot formation, which have the effect of prevention of cardiovascular disease.
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.
Although polyphenols are widely found in plant-based foods, they differ greatly in content and structure in different foods. Moreover, the content of polyphenol in plants is affected by many factors, such as maturity, variety, processing and storage conditions.
The chemical name of BHT is 2, 6-2 tert-butyl - 4-methylphenol, which is used as the raw material for cresol and isobutanol, as catalyst with concentrated sulfuric acid, and alumina as dehydrating agent, and the reaction generates 2. 6-2 tert-butyl - butyl. Used as an antioxidant in food processing. Antioxidants are organic compounds that can inhibit or delay the oxidation of high polymers and other organic compounds in the air. In layman's terms, it is the material that prevents the material from oxidizing due to oxidation.
Antioxidant BHT can inhibit or delay oxidative degradation of plastic or rubber to extend service life.
Antioxidant BHT can prevent the acid value or viscosity of lubricating oil, fuel oil.
Antioxidant butylated hydroxytoluene and synthetic rubber (nitrile, polyurethane, butyl benzene, butadiene, etc.), polyethylene, PVC stabilizer, antioxidant phenolic antioxidant butylated hydroxytoluene is commonly used in rubber, antioxidant butylated hydroxytoluene of natural rubber, butadiene, styrene butadiene, butyl, isoamyl, nitrile, synthetic rubber, such as ethylene propylene acrylate and latex products hot oxygen aging has protective effect, antioxidant butylated hydroxytoluene can inhibit copper, with the ozone resistance and wax and can prevent climate of various factors on the analysis of the damage. It is easily dispersed in rubber, antioxidant butylated hydroxytoluene directly mixed with rubber or as dispersions in latex, can be used in the manufacture of the sidewall of the tire, white, bright color and transparent color of all kinds of rubber and dairy products as well as the daily, health care, tape, rubber shoes and grocery rubber products, antioxidant butylated hydroxytoluene also can be used as a stabilizer of synthetic rubber processing and storage.
The solubility of antioxidant BHT was 0.5% (20), 30% (25) of soybean oil, 20% of cottonseed oil (25), 40% lard (40).
Antioxidant BHT can be used as a food additive to delay the acid failure of food. Antioxidant BHT is used in animal and vegetable oils and fats and oils. In addition, the antioxidant BHT can also be used in ink, adhesives, leather, casting, printing and dyeing, coatings and electronics industries.
