Introduction to Nucleating Agents
Nucleating agents are critical additives used to promote the crystallization process in polymers. During the cooling of molten polymers, they provide heterogeneous nucleation sites, significantly accelerating crystallization rates, increasing crystallinity, and refining crystal grain size. This enhances key properties of the final product – including transparency, rigidity, heat resistance, dimensional stability, and processing efficiency – making them essential additives for optimizing the performance of semi-crystalline plastics (e.g., PP, PE, PA, PBT).
Product Name: Nucleating Agent
Appearance: White or off-white fine powder
Core Functions:
Accelerated Crystallization: Significantly reduces cooling/crystallization time for polymers (especially polypropylene/PP), enhancing production efficiency.
Performance Enhancement:
Improved Rigidity & Heat Resistance: Increases heat deflection temperature (HDT) and flexural modulus of products.
Enhanced Dimensional Stability: Reduces shrinkage and warpage deformation, improving dimensional accuracy.
Optimized Surface Gloss: Imparts superior surface finish to products.
Promoted Transparency (α-nucleation): Specific grades significantly enhance transparency in PP and other materials.
Grain Refinement: Forms uniform, fine crystal structures, elevating overall mechanical properties.
Application Fields:
Polypropylene (PP) Injection Moldings: Thin-walled products, food containers, household items, toys, electrical components.
Polypropylene (PP) Films: BOPP (Biaxially Oriented PP), CPP (Cast PP) films (transparent grades required).
Other semi-crystalline polymers benefiting from enhanced crystallization performance (e.g., PA, PBT).
Recommended Dosage: Typically 0.1% - 0.5% of the polymer matrix weight. Optimal dosage should be determined based
