Product Detail

CAS 7631-86-9 Nano Silica Nucleating Agent Improve Dimensional Stability of Molded Plastics

Product Overview

CAS 7631-86-9 Nano Silica is a high-performance inorganic nucleating agent for molded plastics. With ultrafine particle size and good dispersion, it generates abundant nucleation sites inside polymer matrix to realize uniform crystallization. This product effectively reduces shrinkage, warpage and internal stress during molding, greatly improving dimensional accuracy and stability of injection and extruded plastic parts. Featuring excellent thermal stability and broad resin adaptability, it is an ideal additive for precision molded plastic products.

Core Features

Optimize Uniform Crystallization

Form even crystal structure inside plastics, avoid uneven crystallization caused by slow nucleation.

Reduce Shrinkage & Warpage

Relieve internal stress of molded parts, effectively control deformation and improve dimensional repeatability.

Outstanding High Temperature Stability

Inorganic silica material, no decomposition, discoloration or volatile matter under plastic processing temperature.

Good Dispersion Performance

Uniform ultrafine powder, easy to blend with various resins, less agglomeration during extrusion and injection molding.

Enhance Overall Mechanical Performance

Simultaneously increase rigidity and heat resistance of finished plastic products.

Product Specifications
