Dow DGDA-5310 GMB是一种中等密度聚乙烯树脂,设计用于覆盖通过吹塑薄膜挤出生产的要求严格的土工膜市场。它具有优良的机械性能,无论是在拉伸和撕裂,以及在侵蚀性环境中的抗裂性,广泛符合GM13的要求。利用最高密度的MDPE使DGDA-5310NT产品渗透性低,对水和其他液体介质提供了良好的屏障。由于其中等密度,陶氏树脂有助于挤压过程中的缠绕过程,以及在安装土工膜时适应地形的不规则性。原理特点:为土工膜设计的树脂在高厚度下具有优异的加工性、优异的抗静电腐蚀性和抗氧化性,符合GM标准13。 DOW™ DGDA-5310 GMB is a Medium Density Polyethylene resin designed to cover the demanding geomembrane market that is manufactured by blown film extrusion. It has excellent mechanical properties, both in tensile and tear and resistance to cracking in an aggressive environment, complying extensively with the requirements of GM13. Utilizing the highest density MDPE allows gives DGDA-5310 NT low product permeability, providing an excellent barrier to water and other liquid media. Thanks to its medium density, the Dow resin facilitates the winding process during extrusion and the adaptation to the irregularities of the terrain during the installation of the geomembranes. Principle Characteristics: Resin designed for geomembranes Excellent processability in high thickness Excellent ESCR and oxidation resistance Meets GM Standard 13 |
