Polyethylene: Coal-based polyolefins are in production

On May 20, 018, the Yanan Nenghua project's 450,000 tons/year polyethylene (HDPE) device particle receiving hopper sampler flowed out, marking the success of the 60% load of the largest single extrusion capacity granulator in the world. Produce qualified polyethylene pellets. The test of the extrusion granulation unit took 4 hours and created a new height in the test time.

Since the first domestic coal-based polyolefin plant Shenhua Baotou was put into production in 2010, coal-based polyolefins have springed up and peaked. Especially after 2013, the process has matured and developed rapidly. Up to now, domestic coal-based polyolefin production capacity It reached 9.22 million tons per year, breaking the pattern of two barrels of oil and dividing the market, and truly became a three-legged.

At present, China's polyethylene still has 60%-70% of the demand needs to be imported, especially HDPE and high-end LLDPE. The devices that will be put into production in the future will be mainly LLDPE and HDPE, which will continue to fill the domestic level to some extent. Resource vacancies, the country is gradually increasing the refined development of the industry, firmly differentiated and high-performance routes, to the high-end products, domestic capacity to meet self-sufficiency still has a certain way to go.
