What are the uses and properties of CPE chlorinated polyethylene？
Performance of CPE: 1. It is anti-aging, resistant to ozone, and can be used in different climatic environments. 2. Good flame retardancy can be applied to the production of cable protection pipelines. 3. It can still maintain the toughness of the product in an environment of minus 20 deg...Read more -
PVC processing aids are a type of chemical additive used in plastic production, and there are many types of PVC processing aids. What are the functions of different PVC processing aids?
Heat stabilizer: Plastic processing and shaping will undergo heating treatment, and during the heating process, the plastic is inevitably prone to unstable performance. Adding heat stabilizers is to stabilize the performance of PVC materials during heating. Improved processing aids: As the name...Read more -

Precautions when choosing chlorinated polyethylene: CPE chlorinated polyethylene is widely used in refrigerator magnetic strips, PVC door and window profiles, pipe sheets, fittings, blinds, wire and cable sheaths, waterproof rolls, flame-retar...Read more -
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 -
Key points of process control for PVC foaming regulator
PVC foaming regulator can help us bring good properties during the production and processing of PVC, enabling our reactions to proceed better and produce the products we want. However, we also need to pay attention to several key industrial con...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 -
Advantages and disadvantages of calcium zinc stabilizers
During the plasticization process, calcium zinc stabilizers have a high electronegativity, and the acute nodes of PVC resin have a certain affinity, forming strong bond energy complexes. Calcium zinc stabilizers can be divided int...Read more -
Everyone knows about PVC processing aids. What are the problems with PVC processing aids in the industry?
1. MBS technology and development are slow, and the market is broad, but the market share of domestic products is relatively low. Although it has undergone more than 20 years of development, the domestic MBS industry is currently o...Read more -
What are the characteristics of environmentally friendly calcium zinc stabilizers:
What are the characteristics of environmentally friendly calcium zinc stabilizers: Calcium zinc stabilizers are nitric oxide synthases composed of calcium zinc organic salts, hypophosphite esters, polyether polyols, antioxidants, and organic solvents. Calcium zinc stabil...Read more -

Analysis of the main varieties of ACR processing aids
1. Universal processing aids: Universal ACR processing aids can provide balanced melt strength and melt viscosity. They help accelerate the melting of polyvinyl chloride and have excellent dispersibility under low shear conditions. After use, the most ideal balance betwe...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
