Calcium zinc stabilizer is a non-toxic thermal stabilizer synthesized by a special composite process, mainly composed of calcium salts, zinc salts, lubricants, antioxidants, etc. It is an important additive for thermosensitive polymer materials such as PVC, PVDC, PCTFE, CPVC, chloroprene rubber, etc. It is used to prevent or delay their thermal degradation. Today, Sainuo will take you to learn about the role of ope wax in calcium zinc stabilizers.

The mechanism of action of calcium zinc stabilizer
1. It can replace active groups in polymer chains (such as chlorine atoms at the allyl position in PVC) to obtain more stable polymers, thereby eliminating the source of dehydrochlorination in polymer materials and reducing the possibility of initiating dehydrochlorination reactions.
2. It can quickly capture the detached hydrogen chloride and inhibit its automatic catalytic effect
So what is the role of oxidized polyethylene wax in calcium zinc stabilizers? In the manufacturing process of various soft and hard PVC products, not only heat stabilizers are needed, but also lubricants. Calcium has poor lubricity, so it is necessary to add wax additives to improve the lubrication effect of the product.

The performance improvement of oxidized polyethylene wax on calcium zinc stabilizer is as follows:
1. Oxidized polyethylene wax molecules contain functional groups such as groups, which can enhance the thermal stability of Ca/Zn stabilizers.
2. It can improve compatibility with PVC, reduce frost phenomenon, improve printability and heat sealing.
3. It can promote plasticization and improve the flowability of PVC materials.
4. It has excellent lubrication effect and endows rolling, extrusion, injection, and blow molding equipment with good metal demolding performance.
