Scope of application
Aryl phosphate salt nucleating agents are mainly used to improve the crystallization behavior of polypropylene in the following scenarios:
. PP type: homopoIymerized PP, copoIymerized PP (e.g. random copoIymerization, bIock copoIymerization)
. Processing: injection moIding (e.g. thin-waIIed products, automotive parts),
extrusion moIding (fiIms,fibers), bIow moIding (containers).
. End-use areas:
。 Automotive industry: instrument paneIs, bumpers (to improve rigidity and heat resistance).
。 Packaging materials: transparent containers, food packaging (need to combine with other transparency
agents).
。 Home appliances and electronics: heat-resistant housings, connectors.
。 Fiber products: high-strength fibers (e.g., carpets, nonwovens)
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.
. 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 usuaIIy 50-60%).
