Features
• The nucleating agent BLK-7985(TMB-5) is a representative variety of amide-type polypropylene β-crystal nucleating agent. It can dissolve in the resin melt at the processing temperature of polypropylene (PP), and recrystallize with the decrease of melt temperature to form rod-shaped crystals with larger aspect ratio, thus inducing the nucleation of PP with β-crystalline crystals to improve the impact strength, heat deflection temperature and microporosity of products. In contrast, BLK-7985(TMB-5) has a stable structure and the β-crystalline content of PP is not affected by repeated melt extrusion.
 
Application
• Widely used in PP-R pipes, injection molding products and dry lithium battery diaphragm preparation process, and it has good synergistic effect with calcium carbonate. In addition, BLK-7985 has a nucleation promoting effect on polybutene-1 (PB-1).
