Nucleating transparent agent THT-3 promotes resin crystallization by providing crystal nucleus, which makes the crystal structure fine, thus improving the rigidity, thermal deformation temperature, dimensional stability, transparency and surface gloss of products. In addition, nucleating transparent agent can shorten the molding cycle of products, expand the processing conditions, and enhance the surface smoothness of products. Nucleating transparent agent THT-3 is the third generation sorbitol nucleating transparent agent, which has the same chemical structure and application performance as Milliad 3988. Compared with the first generation DBS and the second generation MDBS, it has better biological applicability. The product is non-toxic and tasteless, and will not produce an odor that is unacceptable to ordinary people during processing. Nucleating transparent agent THT-3 is especially suitable for the resin of high-grade polypropylene products, such as medical supplies, food packaging, etc., and is more suitable for manufacturing food packaging materials than the second generation.

Application of nucleating transparent agent THT-3:
Nucleating transparent agent THT-3 is very suitable for manufacturing transparent plastic products, such as medical supplies, cultural goods, beverage packaging, transparent cups, bowls, basins, plates, CD boxes, etc., as well as high-temperature disinfection products. It is also widely used on transparent PP sheets and transparent PP tubes. Nucleating transparent agent THT-3 can be directly mixed with PP, or made into 2.5~5% masterbatches for reuse, Generally, the addition of nucleating transparent agent THT-3 at 0.2~0.4% has a significant effect on the transparency. The recommended dosage is 0.2~0.4%, and the processing temperature is 190~260 ℃.
Packaging and storage of nucleating transparent agent THT-3:
The inner package is 5kg or 10kg composite bag, and the outer package is carton, which should be stored in a cool and dry place. It can be stored for three years without opening. If the product is not used up, the bag mouth should be fastened.
