牌号简介 About
依凡坦28-800是由乙烯和醋酸乙烯经高压自由基聚合而成的无规共聚物。醋酸乙烯酯28-800含量高,具有柔软性、柔韧性和极性。Evatane 28-800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。Evatane 28-800与大多数填料具有高粘合强度,可用于生产母料。它还可用作各种EVA基化合物的粘度改进剂,例如电线和电缆的HFFR配方。 EVATANE? 28-800 is a random copolymer of Ethylene and Vinyl Acetate made by high-pressure radicalar polymerization process. The high Vinyl Acetate content of EVATANE? 28-800 brings softness, flexibility and polarity. EVATANE? 28-800 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. EVATANE? 28-800 delivers high cohesive strength with most fillers and may be used to produce masterbatches. It can also be used as a viscosity modifier for various EVA based compounds such as HFFR formulations for wires and cables.
