• TMB-5 Nucleating Agent for PP
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).
