Product Detail

Product Introduction

High Dispersion Nano Silica CAS 7631-86-9 is a multifunctional inorganic nucleator developed for polyolefin modification. Featuring ultra-fine nano particle structure and outstanding dispersibility, this product can form uniform heterogeneous nucleation sites inside PP, PE and other polyolefin resin matrices. It accelerates crystallization speed, refines crystalline grains and increases overall crystallinity of polyolefin materials. The modification effect helps enhance material rigidity, surface gloss and dimensional stability, and effectively relieve shrinkage and warpage defects of molded products.

This nano silica possesses excellent chemical inertness and thermal stability. It will not decompose or produce harmful substances under regular polyolefin processing temperatures, and can be well adapted to injection molding and extrusion production processes. Apart from nucleation effect, it also brings partial reinforcing performance, improving scratch resistance and surface finish of polyolefin finished parts. It is an eco-friendly multi-purpose additive widely favored by polyolefin modification manufacturers.

Core Advantages

Excellent dispersibility. Special surface treatment reduces particle agglomeration, enabling uniform distribution in polyolefin melt, avoiding surface defects such as fish eyes and streaks on plastic products.

Efficient nucleation performance. Promote crystallization, refine internal crystal structure, lower molding cycle and improve production efficiency during processing.

Improved dimensional stability. Reduce molding shrinkage and product warpage, help manufacturers produce polyolefin parts with stable size.

Good thermal and chemical stability. Inorganic silica structure resists high temperature processing, no discoloration, compatible with most polyolefin formulations.

Multi-functional modification effect. Realize nucleation and reinforcement simultaneously, optimize surface texture and mechanical properties of polyolefin materials.

Application Scope

High Dispersion Nano Silica CAS 7631-86-9 is mainly applied to polyolefin modification systems including PP and PE. It is widely used for plastic injection parts, extruded sheets, plastic containers, daily plastic products and modified polyolefin masterbatch.

It can be used alone as inorganic nucleator, or compounded with other nucleating agents to reach customized performance requirements. Preform small batch testing is recommended before formal mass production for new formulas.

Usage Guidance

Determine the suitable addition dosage according to target physical indicators of modified materials. Mix nano silica evenly with polyolefin pellets by high-speed mixer before feeding. Adopt standard processing parameters of polyolefin, avoid excessive temperature and long-time material retention inside the equipment. Sufficient mixing is critical to give full play to nucleation and modification performance.

Packaging and Storage

The product adopts sealed moisture-proof packaging to prevent moisture absorption and particle agglomeration. Store in dry, cool and ventilated warehouse, keep away from humid air, direct sunlight and high temperature heat sources. Tightly seal the package after each sampling. Under proper storage environment, the product can maintain stable physical and chemical properties within shelf life.
