牌號簡介 About
依凡坦28-800是由乙烯和醋酸乙烯經(jīng)高壓自由基聚合而成的無規(guī)共聚物。醋酸乙烯酯28-800含量高,具有柔軟性、柔韌性和極性。Evatane 28-800與大多數(shù)增粘樹脂和蠟兼容。結(jié)合高流動性,它是一個高效和容易處理的產(chǎn)品熱熔膠配方。Evatane 28-800與大多數(shù)填料具有高粘合強(qiáng)度,可用于生產(chǎn)母料。它還可用作各種EVA基化合物的粘度改進(jìn)劑,例如電線和電纜的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.
