Use:

Antioxidant 264 (T501) is one of the most common type of phenolic antioxidants important, widely used in polymer materials, petroleum products and medical and food processing industry.

This product is effective in some polymer materials in antioxidant in polyethylene, PVC (the amount of 0.01 - 0.1%) and vinyl ether is an effective stabilizer. The effect of preventing discoloration and loss of mechanical strength is prevented in the polystyrene and the polymer and the material, and the protective effect of the aging of the cellulose and the cellulose ether in the race Lu Lu is protective. This product is the heat stabilizer of polypropylene in the synthetic fiber, the amount of 1%.

This product is a variety of petroleum products, excellent anti oxygen additives, the working temperature of 100 degrees, the best anti oxygen effect. It is widely used for fuel oil and lubricating oil industry, paraffin antioxidant and anti adhesive additives, and can be directly transferred into the mother liquor, adding rubber plastic, wax and other petrochemical products, to improve product anti oxygen performance and prolong its service life. Combined with long chain alkaline ZDDP, ICP metal minus live anti rust agent, can be used to modulate the anti wear hydraulic oil and other products. The dosage of additives in general 0.11%.

This product is a commonly used rubber antioxidant. The dosage of additives in general 0.11%.

This product is a commonly used rubber antioxidant. Heat, oxygen aging has a protective effect, but also to inhibit copper damage. With the anti - ozone agent and wax and the various factors that can be used to prevent the damage of the curing rubber. In the styrene butadiene rubber can be used as a gel inhibitor. This product is volatile. It is easy to disperse in the rubber, which can be mixed directly into the rubber or the rubber as the dispersion. Widely used in natural rubber, synthetic rubber and latex, the product does not change color, nor pollution. Used for the manufacture of the side wall of the tire, white, red and transparent, and a variety of rubber in the general amount of 0.5 - 3. When the dosage is increased to 5 - 3 copies will not spray cream. This product can also be used as a stabilizer for the post treatment and storage of synthetic rubber.
