摘　　要：阐述了某聚乙烯专用树脂DMDA 6200的生产与应用过程,对该产品的技术指标、生产过程、工艺路线、产品质量等进行确定、分析和测试。新产品的MFR为0.36~0.40 g/10 min,密度为0.951~0.956 g/cm^3,拉伸屈服应力≥21 MPa,拉伸断裂标称应变≥350%。产品应用于生产200 mL中空制品,可以代替现有低压小中空树脂HDPE 5502和HDPE 5500B的混配料。所生产的制品外观、成型性、气味、强度等技术指标均能满足用户要求。This paper expounded the production and application process of special PE resin DMDA6200, and made determination,analysis and test to the technical indexes, production process, process route, and product quality. The new product’s MFR is 0.36~0.40 g/10 min, density is 0.951~0.956 g/cm3, tensile yield strength is ≥21 MPa, and nominal tensile strain at break is ≥350%. The product is used for production of 200 mL hollow articles, can replace the existing compound of small hollow container resins HDPE 5502 and HDPE 5500B. The articles produced meet the requirement of the endusers in terms of appearance, moldability, odor and strength.
