Lead Salt Stabilizer
Introduction
Lead salt stabilizer a solid and liquid composite stabilizer with a synergistic mixture of components.Lead salt stabilizer has strong thermal stability, good dielectric property, and low price. Reasonable ratio with lubricant can make PVC resin processing temperature range wider, and the quality of processed and post-processed products stable, is the most commonly used stabilizer at present.Lead salt stabilizer is mainly used in hard products. Lead salt stabilizer has the characteristics of good heat stabilizer, excellent electrical performance and low price.But lead salt is toxic, cannot be used in contact with food products, can not be made transparent products, and is easily contaminated with sulfide to produce black lead sulfide.
Application
Mainly used in PVC profile, foamed sheet, pipe, pipe, fence, wall, cover plate and other outdoor PVC products.
Classification of lead salt stabilizers
Lead salt stabilizers can be divided into three types :
(1) simple lead salt stabilizers, most of which are base-salt salts containing PbO;
(2) Heat stabilizer with lubricating effect, mainly neutral and basic salt of fatty acid;
(3) Composite lead salt stabilizers and solid and liquid composite stabilizers containing a synergistic mixture of lead salt and other stabilizers and components.Product parameter.
