The green composite calcium-zinc composite heat stabilizer has replaced traditional composite lead and organotin heat stabilizers. Through continuous optimization Formula system, improve equipment and process parameters, to solve the production of poor thermal stability, additives precipitation, lower production stability, narrow processing window and other related issues.
