Xinjiang Asia Europe Network on September 26th, the Dushanzi Petrochemical Corp of high-end products added a new member, the company in cooperation with the United States Univation company developed heat-resistant polyethylene DGDZ3606 successful trial production, becoming the world's first BMC PE-RT (heat-resistant polyethylene catalyst heating pipe production company) trial, the trial process is stable, the activity of catalyst and achieve the desired design load.
It is reported that heat-resistant polyethylene, also known as PE-RT, is a method of copolymerization of ethylene and alpha olefins. The polyethylene with special molecular structure is obtained by controlling the number and distribution of branched chains. As a kind of non crosslinked polyethylene material, PE-RT not only retains the low temperature resistance characteristics of PE pipe, and improve its creep resistance at high temperatures and strength in recent years become a new material application field of hot and cold water inside the building gradually.
The Research Institute of petrochemical DN20 pipe sampling preparation process, melt viscosity, water ring control margin, product appearance, excellent internal and external wall is bright bright transparent, smooth, soft products, comparable with the commercial products.
At present, the domestic market demand of PE-RT in the amount of more than 400 thousand tons of imported materials, more than 70% market share, domestic raw materials only a stable production of raw materials of Sinopec, PetroChina is still not stable and continuous production of similar products. The successful trial production of DGDZ3606 indicates that Dushanzi Petrochemical Corp has taken a solid step in the development and production of high-end products.
