BX NA 101 Nucleating Agent for PET/PBT


Chemical name: Nucleating agent BX NA 101

Synonym: Clariant Licomont NAV 101



BX NA 101 is used in a Nucleating Agent for PBT or PET to improve the nucleation effect, Shortening the crystallization time can greatly improve the demoulding efficiency.

It can improve the following performance:

 Shorten the molding cycle

 More conducive to mold filling

 Conducive to de-molding

 Extrusion or injection molded products have good dimensional stability

 Higher thermodynamic properties
