Calcium Zinc Stabilizer, CAS 1592-23-0, is an environmental friendly lead-free heat stabilizer designed for rigid PVC pipe, profile and fitting production. It is formulated based on calcium and zinc metallic soap system. It effectively inhibits thermal decomposition and discoloration of PVC resin under high-temperature extrusion process. This stabilizer delivers balanced thermal stability, lubrication and processing property. It is widely used for non-toxic PVC pipe, building profile and injecti
Product DetailsChemical IdentityProduct Name: Calcium Zinc Stabilizer CAS No.: 1592-23-0 Chemical Type: Lead-free calcium zinc metallic soap heat stabilizer Physical Form: White fine powder Core Feature: Lead-free heat stabilizer for PVC pipe, profile and fitting
Key Performance & TDSThis calcium zinc stabilizer provides excellent long-term thermal stability during PVC extrusion and molding. It reduces PVC chain scission and prevents yellowing or blackening at processing temperature. Built-in balanced internal and external lubrication improves resin flow, reduces screw torque and boosts surface smoothness of finished pipe, profile and fitting. Lead-free and heavy metal free formula complies with environmental regulations. It has good compatibility with PVC resin and common additives such as calcium carbonate, processing aids and impact modifiers. It maintains good mechanical strength and weather resistance of finished PVC pipe and profile. It avoids toxic heavy metal release during product service and recycling.
