The problem of replacing lead salts with calcium zinc stabilizers needs to be solved
Solid composite calcium zinc stabilizers are mainly composed of stearic acid soap, followed by lauric acid soap and oleic acid soap. The product is characterized by good lubricity and does not lower the softening point of PVC hard products, making it suitable for processing hard PVC pipes and pro...Read more -
What are the color issues after 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 transformed from lead salt t...Read more -
ACR processing aids are added during plastic processing, which can provide the physical properties of the product. How to improve the physical performance of the product?
ACR processing aids are added during plastic processing, which can provide the physical properties of the product. How to improve the physical performance of the product? 1. Promoting plasticizing processing aids: This type is widely used in hard PVC products, mainly to promote plasticization, im...Read more -
What are the uses and precautions of PVC foaming regulator
The use of PVC foaming regulator: The foaming of PVC material is to make the molecular distribution of PVC more uniform. Make the quality of PVC products more objective. The PVC sheet foamed by PVC foaming regulator has a very good independent structure. Sometimes, while using PVC foaming regulat...Read more -
The difference between calcium zinc stabilizer and composite lead salt stabilizer:
Calcium zinc stabilizer and composite lead salt stabilizer refer to PVC heat stabilizers, which play a role in thermal stability in PVC product production. The difference between the two is as follows: Calcium zinc heat stabilizers meet environmental requirements and are currently widely used. I...Read more -
What is the role of calcium zinc stabilizer in pvc products?
Calcium and zinc stabilizer is synthesized by a special composite process with calcium salt, zinc, lubricant and antioxidant as the main components. It can not only replace the salts of lead and cadmium and toxic stabilizers such as organotin, but also has good thermal stability, light stability ...Read more -
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
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
