What are the main characteristics of PE film is it? It has good electrical properties, especially high insulation dielectric strength, making it suitable for wire and cable. Medium to high molecular weight grades with excellent impact resistance, even at room temperature at -40F temperatures are so low. Various grades of PE film is an appropriate combination of the unique characteristics of four basic variables: density, molecular weight, molecular weight distribution and additives. Different catalysts are used to produce customized special performance polymers. Welcome to our Alibaba store: 000 large plastic (Shenzhen) Co., Ltd., to negotiate with us, oh!
