Nucleating Transparent Agent ZC-3: Nucleating transparent agent ZC-3 promotes the resin to crystallize
by providing crystal nucleus and makes the structure of the crystal
grain fine, thus improving the products’ rigidity, heat distortion
temperature, dimension stability, transparency and luster. In
addition, nucleating transparent agent ZC-3 can shorten the molding
cycle of products, expand the processing conditions and strengthen
the smoothness. Nucleating transparent agent ZC-3, the third
generation of sorbitol nucleating transparent agent, has the same
chemical structure and application performance with Milliad 3988.
Compared with the first generation DBS and the second generation
MDBS, it has superior biological applicability, as it is non-toxic
and tasteless and will not produce undesirable smell when
processing. Nucleating transparent agent ZC-3 is especially
applicable to resin of top-grade polypropylene products, such as
medical supplies and food packaging. And it is more suitable for
food packaging materials than the second generation. Performance IndicesZC-3:

ApplicationZC-3: Nucleating transparent agent ZC-3 is especially applicable to
transparent plastic products like medical supplies, stationery,
beverage packaging, transparent cups, bowls, basins, plates, CD
boxes and so on, also fit for the high-temperature sterilization
products and widely used in PP sheet and transparent PP tubes. It
can directly be used after mixing with PP dryly and also be used
after being made into 2.5~5% seed grains. Generally, the
transparency of 0.2~0.4% nucleating transparent agent is rather
significant. The proposed amount of addition is 0.2~0.4% and the
processing temperature is190 ~ 260 ℃. Packaging & StorageZC-3: With 5 kg or 10 kg compound bags as inner packaging and cartons as
outer packaging, the nucleating transparent agent ZC-3 is
preferably preserved in a cool and dry place. It can be stored for
three years before unsealing; and the bag should be tied up if the
bag is unsealed and the product is not used up.
