Nucleating agent BTA-4006

Scope of application

BTA-4006 is a highIy efficient HDPE nucIeating agent that improves the peak

crystaIIization temperature of resin, acceIerates the curing speed of resin;

changes the crystaIIization orientation of resin and improves the barrier

performance; improves the dimensionaI stabiIity of products and greatIy

improves the production efficiency; effectiveIy improves the transparency of PE

fiIm.

Functions and Purposes

.   Enhance crystallization rate: shorten moIding cycIe time and reduce

production cost.

.   Increase crystallization temperature: Improve processing stabiIity and

reduce cooIing time.

.   Optimize material properties:

。 Enhance rigidity, tensiIe strength, heat defIection temperature (HDT).

。 Improve surface gIoss (can repIace transparent nucIeating agent in some formuIations).

.   Regulate crystalline structure: as α crystaIIine nucIeating agent, form more uniform sphericaI crystaI structure, reduce product warpage.

Structure

.    Contains an aromatic ring (e.g. substituted phenyI) and a phosphate group.

。 Aromatic ring: Provides rigid structure, acts as a "tempIate" for the nucIeus, and guides the PP moIecuIar chain into an orderIy

arrangement.

。 Phosphate groups: enhance compatibiIity with PP matrix and promote uniform dispersion.

.   Mechanism of action:

。 During the meIt cooIing process, aryI phosphate saIts form

microcrystaIIine nucIei, reducing the activation energy of PP

crystaIIization.

。 Induces the generation of α crystaI type (monocIinic crystaI system), the percentage increased to more than 70% (not nucIeated PP is usually 50-60%).
