牌号简介 About
依凡坦28-25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28-25含量高,具有柔软性、柔韧性和极性。Evatane 28-25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 28-25与大多数填料具有高粘合强度,可用于生产母料或HFFR化合物。Evatane 28-25也适用于薄膜挤出。 EVATANE® 28-25 is a random copolymer of Ethylene and Vinyl Acetate made by high-pressure radicalar polymerization process. The high Vinyl Acetate content of EVATANE® 28-25 brings softness, flexibility and polarity. EVATANE® 28-25 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® 28-25 delivers high cohesive strength with most fillers and may be used to produce masterbatches or HFFR compounds. EVATANE® 28-25 is also suitable for film extrusion.
