Applications:
Nucleating transparent agent NA3988 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.
NA3988 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 ℃.
Packing & Storage
