5 Must-Have Features in a Lead Salt Stabilizer

Compound stabilizer is composed of three salt-based lead stearate, two salt-based lead sulfite, lead stearate, PE wax, stearic acid, calcium carbonate by a special composite process. Such products have good adsorption, can improve the whiteness of PVC products, shorten HC removal time by PVC, and play a role in reducing the amount of stabilizer, improve processing performance, weatherability, stability, and reduce costs, so that the surface the processed product has good physical properties, and the various components of the composite heat stabilizer can be well mixed in the production process as well as greatly improve the uniformity of the mixed dispersion with the resin. Due to the good thermal stability, especially the long-term thermal stability effect, these stabilizers are widely used in the material production of PVC products.
