Fifth, use: a PVC stabilizer and lubricant, a stabilizing effect on a long, long-term heat stability is still good, do non-toxic food packaging, medical equipment, vessels and other soft PU membrane. In polyethylene, polypropylene, as halogen absorbent can eliminate residual resin catalyst resin color and stability of adverse effects. This product is also widely used as polyolefin fibers and molded products of the lubricant, but also for phenolic, amino and other thermosetting plastics and polyester reinforced plastic lubricants and mold release agent, grease thickening agents, waterproofing agents for textiles and paint the plain agent.
