How to choose PVC heat stabilizer in plastic formulation design 2023-04-11
The main reason for adding PVC thermal stabilizer in plastic formulation design is that it can capture the HCL released by PVC resin with self-catalytic action
How to choose PVC stabilizer and lubricant 2023-04-11
Wood plastic formula is generally composed of PVC resin and wood fiber and inorganic filler(wood powder,calcium carbonate)
PVC stabilizing agent for door and window profiles must be no less than just right 2023-04-11
In the process of profile production,the main role of PVC stabilizer is to degrade or react with the released hydrogen chloride and prevent the discoloration of PVC during processing.Attention should be paid to the amount of PVC stabilizer in the processing of door and window profiles.
Application of calcium zinc stabilizer in PVC hard products 2023-04-11
Calcium zinc stabilizer is widely used in the plastic industry as a stabilizer for PVC pipe. For a long time, lead salt and barium, cadmium soap stabilizer has been the world PVC heat stabilizer market because of its low price and excellent performance. Although lead salt and cadmium heat stabilizer used in traditional PVC processing has excellent heat stability performance, its harm to the body and the environment exceeds its advantage. So the future market trend will definitely be calcium zinc stabilizer.
Calcium zinc stabilizer and other kinds of stabilizer comparative advantage 2023-04-11
Comparative advantage with other kinds of stabilizer: calcium zinc series is the primary research object of stabilizer, this kind of stabilizer price is low, but the heat stubborn achievement is poor, so its use price can not compete with lead salt stabilizer.
Some common sense and application of calcium zinc stabilizer 2023-04-11
It is reported that the current wide application of calcium zinc stabilizer is still in the plastic industry, which is used in the production process of plastic parts, plastic pipes, plastic films, wires and cables. The market trend of these products is largely dependent on the development of the construction industry. Therefore, the rise and fall of the construction industry plays a crucial role in the market demand for calcium and zinc stabilizers.
PVC environmental protection compound stabilizer should have what conditions 2023-04-11
PVC environmental protection composite stabilizer is mainly used in PVC and other chlorine-containing polymers, is a polymer material processing process, especially PVC(polyvinyl chloride) and its copolymer processing process essential additives.
PVC calcium zinc stabilizer formula 2023-04-11
PVC calcium zinc stabilizer formula of the main materials are: calcium stearate, zinc stearate, B dione, phosphite ester, antioxidant, hydrotalcite, PE wax, OPE, EBS.
[Calcium zinc compound stabilizer] composition of specific characteristics 2023-04-11
Calcium and zinc composite stabilizer is composed of organic acid salts of calcium and zinc, and organic auxiliary heat stabilizer such as phosphite ester and solvent. Because it does not contain cadmium, lead, barium and other toxic heavy metals, it is considered as an environmental stabilizer and widely used as a pvc heat stabilizer in the processing of PVC products.
PVC plastic formula design principle 2023-04-11
PVC resin belongs to a class of strong polar polymer, the intermolecular force is large, resulting in PVC softening temperature and melting temperature is high, pure PVC resin generally needs to be plasticized in 160~2100C.
Characteristics of rare earth heat stabilizer for PVC 2023-04-11
The performance characteristics of PVC rare earth thermal stabilizer: rare earth ions have many 4f and 5d empty orbital electron levels, they as coordination center ions can accept 6~12 electron coordination pairs, at the same time, they have a large ionic radius, so it is possible to form 6~12 coordination bonds with different bond energy.
The main application field of PVC rare earth thermal stabilizer 2023-04-11
(1) PVC foam plastic. Using rare earth stabilizer instead of lead, soap and other stabilizers for the manufacture of PVC foams, the resulting foams have high mechanical properties and good heat resistance, so this kind of rare earth stabilizer can replace other stabilizers for the development of high strength and high heat resistance PVC foams. At present, most of the foaming agents used in PVC foaming products are azodicarbonamide (AC) foaming agents.
