• Plastic & Rubber Heat Stabilizers and Lubricants

Calcium Stearate

• Considered an inorganic heat stabilizer, Calcium Stearate – is a white powder used as a stabilizer and lubricant in producing PVC, polyolefins, and other polymers.

  As a stabilizer, Calcium Stearate helps prevent polymers’ breakdown due to heat, light, or other environmental factors. By adding Calcium Stearate 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, Calcium Stearate 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 PVC and polyolefins, Calcium Stearate is a stabilizer and lubricant in producing other polymers, such as polystyrene, polypropylene, and polyethylene. It is often added to the polymer formulation in small amounts, typically between 0.1 and 1% by weight, to achieve the desired stabilizing and lubricating effects.
