Unsaturated polyester resin is generally a linear polymer compound with ester bond and unsaturated double bond, which is formed by polycondensation of unsaturated dibasic acid diol or saturated dibasic acid unsaturated diol. In our country, the material has been widely used and developed rapidly, and now it is an integral part of many glass fiber reinforced plastic objects. Our silica helps control the viscosity of unsaturated polyester resins, improve the Anti-settling and Thickening, while also being an indispensable and efficient thickener.
Insulation materials
The benefits for unsaturated polyester resins
Optimal rheological control for ideal viscosity
Prevents solids from precipitating in the resin
Gel-like resin thins when sheared for easy processing
