上海石化公司年产25万t聚乙烯装置气相反应釜日前投产,生产出合格的双峰聚乙烯。 双峰聚乙烯是指分子量分布曲线呈现两个峰值的聚乙烯,很好地解决了普通聚乙烯的可加工性与力学性能相互矛盾的难题,使制品既有更好的力学性能,又便于加工,在薄膜、建材、管道、电线电缆及吹塑、注塑制品等领域有着广泛的用途。据专家介绍,称为第二代聚乙烯的双峰聚乙烯已经向第一代聚乙烯提出挑战,国外各大石化公司都以较快速度发展,使这种高性能双峰聚乙烯消费量呈上升趋势。北欧化
Shanghai Petrochemical Company with an annual output of 250,000 t polyethylene plant vapor phase reactor put into operation a few days ago to produce qualified bimodal polyethylene. Bimodal polyethylene refers to the molecular weight distribution curve presents two peaks of polyethylene, a good solution to the ordinary polyethylene processability and mechanical properties of the contradictory problems, so that both products have better mechanical properties, but also easy to process , In the film, building materials, pipelines, wire and cable and blow molding, injection products and other fields has a wide range of uses. According to experts, bimodal polyethylene, called the second generation of polyethylene, has challenged the first generation of polyethylene. The major petrochemical companies in foreign countries have been developing at a relatively fast pace, making this high-performance bimodal polyethylene consumption Upward trend. Northern Europe
