Zinc Sulfide

  • Plastic & Rubber Heat Stabilizers and Lubricants

    Zinc Sulfide is a chemical compound commonly used as a pigment, stabilizer, and lubricant in producing PVC, polyolefins, and other polymers. It is a white or yellowish powder.

    As a stabilizer, Zinc Sulfide helps to prevent the breakdown of polymers due to heat, UV radiation, or other environmental factors. By adding Zinc Sulfide to the polymer formulation, the stability and durability of the polymer can be improved, ensuring that it can withstand these conditions without breaking down or degrading.

    As a lubricant, Zinc Sulfide helps to improve the processing and handling of polymers during production. It acts as a mold release agent, preventing the polymer from sticking to the mold during shaping and forming. It also reduces friction between the polymer and the processing equipment, making it easier to extrude, inject, or blow mold the polymer into the desired shape.

    In addition to its stabilizing and lubricating properties, Zinc Sulfide is also used as a pigment in producing PVC, polyolefins, and other polymers. It can be used to give the polymer a white or yellowish color.

    Zinc Sulfide is particularly effective as a stabilizer and pigment in PVC production. It is often used with other additives, such as calcium-zinc stabilizers, to achieve the desired level of stability and color. It is also used as a stabilizer and lubricant in different polymers, such as polystyrene, polypropylene, and polyethylene.
