Fatty acid zinc Description: fatty acid zinc (Zinc Fatty Acid) referred to as ZnFA, industrial products are usually pale yellow particles, anti-sulfide pollution, and can cooperate with calcium soap as a nontoxic stabilizer in PVC resin, natural rubber, synthetic rubber in areas such as widely used. Quality index: Item ZnFA color light yellow or brown powder or granules traits iodine value (gI2 / 100g) 40 ~ 50 Melting point (℃) 97 ~ 103 heavy metals (Pb,%) ≤ 0.0005 Lead (mg / kg) ≤ 100 Cd (mg / kg) ≤ 5 Hg (mg / kg) ≤ 0.02 Ash (%) 12 to 14 Note: Some indicators can be according to customer needs to be adjusted accordingly. Application: The main role of fatty acids in the field of zinc in PVC PVC resin in order to improve thermal stability and thermal aging whiteness, improve the structural characteristics of PVC granules, improve elasticity and tear strength of sulfur compounds. Shrinking agent for rubber tires, the shoe is an excellent dispersant compound. Fatty acids, zinc and rubber, excellent compatibility, non-blooming with plastic solution and lubrication dual function. Natural rubber and compounding or mastication process of synthetic rubber, from the physical and chemical plasticizing effect, also can reduce the mixing or mastication temperature, shorten the mixing time and improve production efficiency, reduce energy consumption, to improve rubber products The passing rate and dimensional stability has a good effect, no adverse effect on the curing characteristics of rubber, does not affect the metal and fiber bonding. Adding 1-5% by the original formula can be added in the raw rubber mastication, can be added at the beginning of mixing with other additives.
