超低密度聚乙烯也被称为第四代聚乙烯,长期以来因受技术能力所限,该产品依赖进口。这种聚乙烯专用料的开发难度远大于普通线型聚乙烯。为尽快赢得这一市场,天津石化采用专用的催化剂体系,对聚合工艺、产品结构和性能进行精心设计,并多次对生产方案、技术指标进行详细讨论,形成了独特的工艺生产技术。 Ultra-low density polyethylene, also known as fourth generation polyethylene, has long been limited by technical capabilities and relies on imports. The development of polyethylene specialty materials is much harder than ordinary linear polyethylene. In order to win this market as soon as possible, Tianjin Petrochemical uses a dedicated catalyst system to elaborate the polymerization process, product structure and performance, and discusses the production scheme and technical indicators on many occasions to form a unique technology for process production.
