Functions of fillers

1. Improve the stability of materials. Fillers can control the shrinkage, thermal expansion and contraction of materials, and improve the mechanical strength and stability of materials.
2. Change the physical and chemical properties of materials. Fillers can increase the thermal conductivity and flame retardancy of materials, improve UV resistance and wear resistance, etc.
3. Reduce costs. Fillers can replace some expensive raw materials, thereby reducing the cost of materials.
4. Improve production efficiency. Fillers can reduce the viscosity of materials, reduce the difficulty of production processes, and improve production efficiency.
