Tne antioxidant effect of antioxidant 1076

Introduction

Antioxidant 1076 is a non polluting non-toxic hindered phenolic antioxidant. Its appearance is white or yellowish solid powder, white crystalline powder, odorless and tasteless[1]. It is easily soluble in organic solvents such as benzene (57g), chloroform, cyclohexane, acetone (19g) and esters, slightly soluble in methanol, ethanol and mineral oil, insoluble in water, stable to light, not easy to change color, no pollution, no coloring, low volatility, water extraction resistance, good compatibility and high antioxidant efficiency. It is widely used in polyethylene, polypropylene, polyoxymethylene, ABS resin, polystyrene, polyvinyl alcohol, engineering plastics, synthetic fibers Elastomers, adhesives, waxes, synthetic rubber and petroleum products. Prevent thermal oxidative degradation of substrate. It is suitable for addition in the polymerization, manufacturing or final use stage of the product. It is often used in combination with auxiliary antioxidant DLTP, 168, etc. to give play to synergistic effect, with better antioxidant performance. The general dosage is 0.1% ~ 0.5%. Excellent antioxidant with good heat resistance and water extraction resistance. It is widely used in polyolefin, polyformaldehyde, ABS resin and various rubber and petroleum products. The product is slightly toxic, and the oral LD50 of rats is more than 10000mg / kg. It can be used for food packaging.

Antioxidant 1076 is a compound antioxidant

Composite antioxidant is the compound of antioxidant pl-10 and antioxidant 1076 or 1010. It also contains main and auxiliary antioxidants. It is widely used in polyolefin, PVC, ABS, nylon, pet, PPO, PBT Alloy, polystyrene and other polymer products. It can effectively improve the processing stability, mechanical strength, color stability and transparency of products and prolong the service life of products. Antioxidant pl-10 is a heat stabilizer and processing stabilizer for polymers such as polyethylene, polypropylene, polycarbonate and nylon. It has the special function of stabilizing the melting index of polymers and can also be used as a synergist. It is less volatile than antioxidant 264 and has no tendency of phenolic antioxidant to turn into colored quinone structure, thus reducing the yellowing index of the product. When used together with antioxidant and light stabilizer, the efficiency of these additives can be greatly enhanced. As a protective agent against radioactivity in PP resin, it has special effect. It has excellent synergistic effect with antioxidants 1076, 1098, 1010, hindered amine light stabilizers 770, 622, 944, etc. Pl-10 is the most hydrolysis resistant phosphite product.

Antioxidant effect of antioxidant 1076

Antioxidant is an organic compound that can inhibit or delay the thermal oxidation of polymers and other organic compounds in air. It is usually very effective as long as 1% tiny concentration of antioxidant is added. For example, foods are prone to oxidative deterioration. A small amount of antioxidants can be added to prolong their storage time. Polymer materials such as plastics, synthetic fibers and rubber are prone to thermal oxygen degradation. Adding antioxidants can maintain the excellent properties of polymer materials and prolong their service life. The closer the antioxidant is added to the aging cycle, the better, for example, before the polymer is dried into powder. Antioxidant pl-440 is a phosphite antioxidant with excellent performance. It can be used as a co antioxidant and heat stabilizer of polymers. It is widely used in PVC, pet, ABS, polyolefin, nylon, PPO, PBT Alloy, polystyrene and other polymers. It can effectively improve the light stability, processing stability, mechanical strength, color stability and transparency of products, and prolong the service life of products. Pl-440 has the special effect of stabilizing the melt viscosity of polymers. This product is non-toxic and can be used as food packaging materials.
