Liquid calcium-zinc stabilizer function and performance

🔍Product Overview 

Liquid calcium-zinc stabilizer is a highly efficient, environmentally friendly thermal stabilizer based on the synergistic action of calcium (Ca) and zinc (Zn), specifically designed for polyvinyl chloride (PVC) processing.

 It completely replaces traditional toxic stabilizers such as lead and cadmium, offering exceptional long-term thermal stability and weather resistance. 

It is suitable for PVC products with strict requirements for environmental friendliness, transparency, and low migration, and complies with international environmental regulations such as the EU REACH and RoHS, meeting food contact and medical-grade standards.
