Product Detail

CAS 7631-86-9 Amorphous Nano Silica Nucleating Agent Improve Plastic Rigidity & Surface Smoothness

Product Overview

CAS 7631-86-9 Amorphous Nano Silica is a high-performance inorganic nucleating agent specially developed for engineering plastic modification. Featuring unique amorphous structure and ultra-fine nano particle size, it delivers excellent nucleation efficiency and uniform dispersion in plastic resin. This product can effectively enhance the structural rigidity and hardness of plastic products, eliminate surface blemishes, scratches and uneven texture, and greatly improve surface smoothness and gloss. With superior thermal stability and compatibility with various plastics, it is a multifunctional additive for upgrading plastic mechanical properties and surface quality.

Core Features

Excellent Rigidity Reinforcement: The amorphous nano structure fills the internal gaps of plastic matrix effectively, significantly improving product rigidity, hardness and structural stability, avoiding deformation under external force.

Upgrade Surface Smoothness Greatly: Uniform nano particles optimize molding fluidity, eliminate surface defects such as pits and rough texture, deliver high-gloss, smooth and delicate product surface.

Stable Amorphous Structure: No crystal agglomeration risk, maintain stable modification effect during high-temperature processing, not easy to affect plastic molding performance.

Superior Thermal & Chemical Stability: Inorganic silica material with high temperature resistance, no decomposition, no discoloration, no volatile substances in plastic processing environment.

Wide Compatibility & Dispersion: Easy to blend evenly with various plastic resins, no agglomeration and precipitation, suitable for injection molding, extrusion and other molding processes.

Product Specifications

Product Name: Amorphous Nano Silica Nucleating Agent

CAS No: 7631-86-9

Material Type: Inorganic Amorphous Nano Additive

Appearance: White Ultra-fine Powder

Core Function: Improve Plastic Rigidity, Enhance Hardness, Upgrade Surface Smoothness

Applicable Resin: PET, PBT, PP, ABS and other engineering plastics

Recommended Dosage: 0.2%–0.8%

Application Scope

Widely applicable to various general and engineering plastic products requiring high rigidity and high surface finish. Mainly used in polyester PET/PBT modified plastics, precision electronic plastic parts, household appliance shells, automotive plastic components, high-gloss injection molded products and other fields.
