牌号简介 About
依凡坦18-150是由乙烯和醋酸乙烯经高压自由基聚合工艺制得的无规共聚物。醋酸乙烯酯含量高的18-500乙烯酯具有柔软性、柔韧性和极性。Evatane 18-500与大多数增粘树脂和蜡兼容。结合高流动性,它是一个高效和容易处理的产品热熔胶配方。也可用作沥青改性的添加剂。 EVATANE? 18-150 is a random copolymer of Ethylene and Vinyl Acetate made by high-pressure radicalar polymerisation process. The high Vinyl Acetate content of EVATANE? 18-500 brings softness, flexibility and polarity. EVATANE? 18-500 is compatible with most tackifying resins and waxes. Combined with a high fluidity, it is an efficient and easy handling product for hot melt adhesives formulations. It can also be used as an additive for bitumen modification.
