Description

FSUN^TMLow specific surface area fumed silica is a specially designed white-color process modifier consisting of spherical, nano, submicron particles of amorphous silicon dioxide. The nature of the product allows excellent dispersion of these particles in the elastomer matrix. This leads to improved dispersion of all compound ingredients and a better flow, allowing higher extrusion speeds,better compression set, better resilience and smoother surface of the end product.

Application

It is mainly used as a processing aid and anti-fatigue agent for a variety of rubber;
It can significantly reduce the viscosity of Mooney, reduce the mixing time, and improve the appearance and mechanical properties of the product;
It can improve heat generation, resilience and compressive change performance, and increase fatigue resistance by up to 50%;
Suitable for silicone rubber, fluorosilicone rubber.
It is suitable for peroxy vulcanization system and addition vulcanization system.

Packaging, storage and transportation

Tons of bag packaging, 150kg-600kg specifications. According to non-toxic, non-dangerous goods storage and transportation.
