Nucleating Agent BT-809

Hello, come to consult our products !

Nucleating Agent BT-809

It is a kind of phosphoric acid nucleating agent with high effective which is applied to polypropylene crystallization behavior. It can reduce linear thermal expansion coefficient and shrinkage of polypropylene, give polypropylene uniform shrinkage characteristics and good assembly of parts, also can refine the crystal size of polypropylene, improve the excellent rigidity and toughness balance of polypropylene. It can accelerate the crystallization rate of polypropylene to improve the production speed and the product performance.
