Recently, Daqing Petrochemical Company's plastic factory produced two kinds of chlorinated polyethylene type B special materials, QL565P and QL585P for the first time, with the output of 331 tons and 201 tons respectively
.
At present, the two products have been respectively sent to downstream rubber product manufacturers for processing tests
According to Zhang Xilai, director of the low-pressure polyethylene workshop of the factory, chlorinated polyethylene resin is a new and environmentally friendly material that can be used to process rubber products, and has better cold resistance, aging resistance, ozone resistance, oil resistance and flame retardant than rubber.
and other performance
.
The annual demand for this special resin is more than 100,000 tons
"For rubber products, the Mooney index is an internationally accepted indicator of rubber processing performance and final product performance.
Rubbers with different Mooney viscosities have different uses
.
QL565P chlorinated polyethylene resin belongs to the middle Mooney index, while QL585P belongs to the middle Mooney index.
The two grades developed and produced this time are developed on the basis of QL505P chlorinated polyethylene powder, which breaks through the restrictions and barriers of the imported process package on the catalyst concentration and ethylene ratio in the polymerization kettle, and finally reduces the relative molecular weight of the product.
Zhang Xilai said that most of the products on the market currently use imported B-type chlorinated polyethylene resin powder with high Mooney index, and the price is relatively high
