Antioxidant 1520 is a new high molecular weight liquid antioxidant, which has certain effect on the stability of rubber and adhesive compound. 1520, it can effectively prevent gel formation and prevent rubber color, molecular weight and viscosity changes during isolation, drying, storage and shipping. 1520 is effective even in rubber processing without the addition of phosphite (TNPP). But if necessary, adding phosphite will make the effect better. At the same time, 1520 can also be used in polymer or organic matrix, including thermoplastic elastomer, synthetic oil, etc.
Purpose:
This product is a rubber antioxidant. Mainly used in cis-butadiene rubber, styrene-butadiene rubber, ethylene propylene rubber, nitrile rubber, thermoplastic elastomer and other synthetic rubber, its dosage is small, antioxidant effect is good, can improve the stability of plastics or synthetic plastics. It belongs to environmental protection antioxidant, and realizes the transformation of rubber products from general type to environmental protection type. This product can also be used in lubricants, plastics and other polymer polymers, with excellent oxidation resistance.
Packing, storage, transportation and precautions:
Galvanized drum packing, net weight 200 kg;
The product should be stored in a clean and dry place to prevent rain.

3. Typical crosslinking temperature: 175 C (rheometer T90 about 12 minutes)
Use of bis-pentadecyl sulfide:
Bis-pentadecane vulcanizer is a bifunctional peroxide, which can be used as crosslinking of natural or synthetic rubber, as well as thermoplastic polyolefins.
Product Specification of Bi-pentadecane Sulfide:
Appearance: White paste with high viscosity: 50 PT-Co Max
Content: 92.0% min ROS: 10.14% min
Organic peroxides are unstable to heat and can produce exothermic self-accelerated decomposition. Self-accelerated decomposition temperature SADT is the lowest temperature at which peroxide may produce self-accelerated decomposition in packaging for transportation. The determination of SADT is based on the "heat accumulation storage test".
