The reasons for the rapid development of new environmentally friendly calcium zinc stabilizers are
When producing plastic products, we use a lot of stabilizers, among which composite stabilizers are the most widely used. Even though lead salt stabilizers are inexpensive and have good thermal stability, they have been widely used. However, th...Read more -
What are the differences between PVC processing aids, plasticizers, and lubricants？
Because PVC processing aids are highly compatible with PVC and have a high relative molecular weight (about (1-2) × 105-2.5 × 106g/mol) and no coating powder, they are subject to heat and mixing during the molding process. They first soften and...Read more -
How to test the addition of inorganic substances i
How to test the addition of inorganic substances in ACR processing aids： Detection method for Ca2+: Experimental instruments and reagents: beaker; Cone shaped bottle; Funnel; burette; Electric furnace; Anhydrous ethanol; Hydrochloric acid, NH3-NH4Cl buffer solution, calcium indicator, 0.02mol/L ...Read more -
What are the color issues after calcium zinc stabilizers replace lead salts?
After the stabilizer is changed from lead salt to calcium zinc stabilizer, it is easy to find that the color of the product often tends to be greenish, and it is difficult to achieve a color change from green to red. After the stabilizer of hard PVC products is transfor...Read more -

In general, there are two main methods: static and dynamic. The static method includes Congo red test paper method, aging o...Read more -
What are the problems in the PVC processing aid market?
1. There is still a certain gap between domestic PVC processing aids and foreign products, and low prices do not have a major advantage in market competition. Although domestic products have certain geographical and price advantages in market competition, we have certain gaps in product perform...Read more -
The physical properties and main functions of PVC processing aids
PVC processing aid is a thermoplastic graft polymer obtained from the polymerization of methyl methacrylate and acrylate through seed lotion. It is mainly used for the processing and production of PVC materials. It has a good effect on improving the impact resistance of PVC materials. It can prep...Read more -
What are the factors that affect the quality of processing aids
1. Viscosity number The viscosity number reflects the average molecular weight of the resin and is the main characteristic for determining the type of resin. The properties and uses of the resin vary depending on the viscosity. As the degree of polymerization of PVC resin increases, mechanical p...Read more
