Zeolite 4A---PVC Thermal Stabilizer
It is a powder with characteristics of good crystallization, free flow and particle optimized,which can be used as a kind of PVC heat stabilizer mixed formulation at flexible and rigid PVC, can replace of lead stabilizer.
Description
In order to better develop the domestic and foreign markets, we uphold the business philosophy of stable product performance and excellent quality, we will continue to provide with the best quality of aluminium hydroxide formula, Boehmite, Alumina Boehmite and the most thoughtful services. By strengthening the management of new product development and aiming at the potential market demand, a series of new products with good prospects have been developed by us. We are brave enough to admit mistakes, take responsibility, reflect problems objectively, and put a stern stop to dishonest behaviors that harm the interests of the company.
It is a powder with characteristics of good crystallization, free flow and particle optimized,which can be used as a kind of PVC heat stabilizer mixed formulation at flexible and rigid PVC, can replace of lead stabilizer. It can significantly improve the thermal stability and anti-tarnishing ability of PVC products. It also can alternatively replace the zinc stearate stabilizers to improve the thermal stability and decrease in the production cost simultaneously.
