The product, non-toxic and not polluted by sulfide, is synthesized by the advanced production
process called “dry method” (top-speed dispersing neutralization method), which is the
stabilizer and lubricant of PVC. When it reacts with the zinc soap and epoxide, the synergism
appears. It is mainly used in the nontoxic soft films and apparatus such as the food package
and armarium etc. moreover, in the hard products it can improve the gelation speed with the
basic lead salt and lead soap. As a helogenic absorb agent, it can eliminate the bad effect of
residual catalyst to the resins color and stabilizer in the resins. It is a lubricant in the polyolefin
fiber and the plastic model products. It is also a lubricant and mold-releasing agent in the
phenolic and amion resins, thermoset plastics and reinforcing PET plastics, also an intensifier
for lubricating ester, a water-proof agent for textiles, a flatting agent for paints. It’s also a
dispersant and lubricant for manufacturing sheet, film, hosepipe and artificial leather, etc. it
can also improve work ability of hard products with stabilizers. |
