Transparent inorganic fillers for plastics play a crucial role in enhancing the mechanical, thermal, and optical properties of plastic materials while maintaining transparency. Here are some commonly used transparent inorganic fillers in plastics:
Nano Silica (Silicon Dioxide)
Nano-sized silica particles are widely used as transparent fillers in plastics due to their excellent transparency, high surface area, and compatibility with various polymers. They enhance mechanical properties and scratch resistance while maintaining optical clarity.
Nano Alumina (Aluminum Oxide)
Nano-alumina particles are another common choice for transparent fillers in plastics. They improve thermal stability, hardness, and abrasion resistance without compromising transparency.
Nano Titanium Dioxide (TiO2)
Nano-TiO2 particles can improve the UV resistance of plastics while maintaining transparency. They are often used in outdoor applications to prevent yellowing and degradation caused by UV radiation.
Nano Zinc Oxide (ZnO)
Nano-ZnO particles are effective UV blockers and are used as transparent fillers in plastics to enhance UV resistance and prevent yellowing or degradation.
Nano Barium Sulfate (BaSO4)
Nano-sized barium sulfate particles are used as transparent fillers in plastics to improve mechanical properties such as hardness and scratch resistance while maintaining optical clarity.
Nano Calcium Carbonate (CaCO3)
Nano-sized calcium carbonate particles can be used to improve the mechanical properties and stiffness of plastics while maintaining transparency.
Nano Cerium Oxide (CeO2)
Nano-cerium oxide particles are used as transparent fillers in plastics to enhance UV resistance, scratch resistance, and mechanical properties.
Nano Zirconium Dioxide (ZrO2)
Nano-zirconium dioxide particles can be used as transparent fillers in plastics to improve mechanical properties such as hardness and wear resistance while maintaining transparency.
These transparent inorganic fillers can be incorporated into various plastic matrices through compounding it’s essential to choose the appropriate filler type, particle size, and loading level to achieve the desired balance between properties such as transparency, mechanical strength, thermal stability, and UV resistance.
