Product Detail

CAS 7631-86-9 Nano Silicon Dioxide Inorganic Nucleating Agent Low Impurity Industrial Grade

Product Overview

CAS 7631-86-9 Nano Silicon Dioxide is a low-impurity industrial-grade inorganic nucleating agent. With ultrafine particle size and high purity, it provides sufficient nucleation sites for polymer resins to accelerate crystallization progress. This product helps improve plastic dimensional stability, rigidity and surface quality. Low impurity characteristics effectively avoid abnormal discoloration and performance fluctuation of finished plastics. It is a reliable nucleation modifier for industrial plastic modification.

Core Features

Low Impurity & High Purity

Strictly controlled impurity content, effectively prevent plastic yellowing, spots and other defects during high-temperature processing.

Excellent Nucleation Performance

Accelerate resin crystallization, shorten molding cycle, improve production efficiency for injection and extrusion processes.

Stable Thermal Property

Inorganic silicon dioxide structure, no decomposition, no volatile substances under common plastic processing temperature.

Good Dispersion

Uniform ultrafine powder, easy to mix with various resins, less agglomeration during twin-screw granulation.

Wide Compatibility

Applicable to multiple polymer systems including PET, PBT, PP and other modified plastics.

Product Specifications

Product Name: Nano Silicon Dioxide

CAS No: 7631-86-9

Grade: Low Impurity Industrial Grade

Appearance: White Ultrafine Powder

Core Function: Promote crystallization, enhance rigidity, stabilize product dimension

Recommended Dosage: 0.2%–0.8%

Application Scope

Widely used in modified engineering plastics, plastic masterbatch, precision injection molding products, electronic plastic components, household appliance plastic parts and automotive plastic accessories.
