Description:
In the production process of FRP, unsaturated polyester resin is an important part of FRP. Our Hydrophilic fumed silica can control the Rheology, the viscosity of FRP and achieve the desired thixotropy and is also an indispensable and efficient thickener.
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 and achieve the desired thixotropy, while also being an indispensable and efficient thickener.
The benefits for Fiber Reinforced Polymer(FRP) and UPR
Optimal rheological control for ideal viscosity
Prevents solids from precipitating in the resin
Gel-like resin thins when sheared for easy processing
