Application
The product is the second generation of sorbitol nucleating transparent agent and the polyolefin nucleating transparent agent largely produced and consumed in the current world. Compared with all the other nucleating transparent agents, it is the most ideal one that can give the plastic products superior transparency, luster and other mechanical properties.
Ideal transparency effect can be achieve only by adding 0.2~0.4% this product into the corresponding materials. This nucleating transparent agent can improve the materials’ mechanical property. It is fit for making plastic products and is also widely used in transparent polypropylene sheet and tubes. It can directly be used after mixing with polypropylene dryly and also be used after being made into 2.5~5% seed grains.
