Features of antioxidant Antioxidant 618

1. This product is a new type of phosphorus-containing antioxidant with excellent performance. It has high effective phosphorus content, strong ability to decompose hydroperoxide, and has excellent initial coloration and transparency.
2. Can be used in food packaging materials, replacing the antioxidant BHT and the auxiliary antioxidant DLTP.
3. Mainly used in polyethylene, polystyrene, polypropylene, ABS resin, ethylene-vinyl acetate copolymer, etc., can also be used for polyvinyl chloride and polycarbonate.
4. This product can be combined with a hindered phenolic antioxidant or a hindered amine light stabilizer to produce a good synergistic effect. The amount of addition is 3 ‰ to 5 ‰.
5. Used as a high temperature antioxidant, often used in combination with hindered phenolic antioxidants, for ABS, PS, HIPS, NBR, SBS, PP, PE, LLDPE, PVC, PC, PA, PET, UP, amide fiber, polyester fiber , adhesives, coatings, inks, composite additives production and processing, calcium and zinc stabilizer compounding.
6. Due to the bisphosphite structure, the alkyl trivalent phosphorus content is higher, so that the antioxidant effect is more prominent and efficient.
7. It is approved by food and health agencies in many countries and can be used in food packaging materials (TITLE21 CFR.178.2010). It is structurally free of alkyl phenol, meets the latest market regulations and development trends, and is better combined with UV absorbers.

Applications

1. Due to its structure and high molecular weight characteristics, it is very suitable for the application of polymeric materials requiring high temperature processing.
2. Antioxidant 618 has a higher content of alkyl trivalent phosphorus due to its bisphosphite structure, which makes the antioxidant effect more prominent and efficient. It has better heat resistance and color retention than antioxidant 168. Antioxidant 618 has the advantages of good compatibility to most plastics, good heat resistance durability, small addition amount, good fluidity to fluid melt, and prevention of yellowing. It is widely used in plastics, rubber, adhesives, etc.
3, the product does not contain phenolic substances, is a good food antioxidant, due to low toxicity, can replace the food antioxidant BHT, has passed the FDA certification of the US Food and Drug Administration, can be used for food packaging grade materials.
4. Antioxidant 618 has outstanding effects on preventing oxidation and improving color; it has high thermal stability, weather resistance and hydrolysis resistance. Therefore, processing stability is good, product transparency is good; no pollution It has a good synergistic effect with UV absorbers and phenolic antioxidants.
5.Toxicity and protection: This product is non-toxic, rat oral LD5010000 mg / kg. Protective measures can be taken according to general chemical products.
