NA-11 is a crystalline nuclear agent, which has the following advantages: 1. Improve the thermal deformation temperature (HDT), the die resistance and the impact resistance strength of the polymer. 2 When measured at low concentrations, significant transparency can be provided. 3. Increase the crystallization temperature of the product. 4. Due to the good product compatibility, so there is no flower and removal problems. NA-11 is used in PP products as food packaging applications. NA-11 is the most suitable crystalline nuclear agent for PP, PET, PBT, and Polyamide. The recommended addition amount is from 0.1 to 0.3%.
