牌號簡介 About
依凡坦20-20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。高醋酸乙烯酯含量的乙烯酯20-20帶來柔軟、柔韌和極性。Evatane 20-20與大多數(shù)增粘樹脂和蠟兼容。結合高流動性,它是一個高效和容易處理的產(chǎn)品熱熔膠配方。Evatane 20-20也可用作原油(降凝劑)和瀝青改性的添加劑。 EVATANE? 20-20 is a random copolymer of Ethylene and Vinyl Acetate made by high-pressure radicalar polymerization process. The high Vinyl Acetate content of EVATANE? 20-20 brings softness, flexibility and polarity. EVATANE? 20-20 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? 20-20 can also be used as an additive for crude oil (pour point depressant) and for bitumen modification.
