The difference between zinc stearate and calcium stearate in use

Calcium stearate and zinc stearate are both a white powder in appearance, both belong to PVC stabilizers, but there are still many differences in their uses.

1. First of all, although both calcium stearate and zinc stearate can be used as lubricants and stabilizers, calcium stearate is mostly used in various plastic processing, while zinc stearate is mainly used in benzene Vinyl resin, phenolic resin, amino resin;

2. Although both can be used as PVC heat stabilizers, calcium stearate is mainly used in polyvinyl chloride, while zinc stearate is mostly used in PVC to inhibit the initial coloring and lubrication. There is no vulcanization pollution, just the effect Limited, it needs to be used in conjunction with stabilizers such as calcium soap and barium soap;

3. Both calcium stearate and zinc stearate can be used as a softener in rubber processing, but calcium stearate can also be used as a plasticizer, which does not affect the vulcanization effect of rubber on the basis of softening, while zinc stearate But it can be used as vulcanization activator and softener;

4. The role of calcium stearate is more extensive. It can not only increase the gelation speed in hard products, but also act as a halogen absorbent in polyethylene and polypropylene to eliminate the influence of residual catalysts on color and stability. It can also be used as a Lubricants for polyolefin fibers and molding compounds, waterproofing agents for textiles, flatting agents for paints, thickeners for greases, plasticizers in the manufacture of plastic records, etc.
