Product Detail

CAS 7631-86-9 Nano Silica Powder Nucleating Agent For Plastic Masterbatch Reinforcement

Product Overview

CAS 7631-86-9 Nano Silica Powder is multifunctional inorganic additive integrating nucleation and reinforcement. With ultrafine particle size and good dispersion, it can form uniform nucleation sites inside polymer matrix, accelerate resin crystallization. Meanwhile, it effectively improves mechanical strength, dimensional stability and surface quality of plastics. It is an ideal raw material for producing all kinds of functional plastic masterbatch.

Core Features

Nucleation & Dual Reinforcement Function

Works as nucleating agent to optimize crystalline structure, and serves as reinforcing filler to boost plastic comprehensive mechanical properties.

Excellent Dispersion Performance

Surface treated nano powder, easy to disperse in various resins, less agglomeration during twin-screw granulation for masterbatch.

High Thermal Stability

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

Improve Product Surface Quality

Reduce surface defects of molded plastics, enhance surface smoothness and texture of masterbatch finished products.

Wide Resin Compatibility

Suitable for PET, PBT, PP, PE and other polymer systems, flexible for different functional masterbatch formulations.
