三元乙丙膠

三元乙丙橡膠是由乙烯、丙烯經溶液共聚合而成的橡膠,再引入第三單體(ENB)。三元乙丙橡膠基本上是一種飽和的高聚物,耐老化性能非常好、耐天候性好、電絕緣性能優良、耐化學腐蝕性好、沖擊彈性較好。乙丙橡膠的主要缺點是硫化速度慢;與其它不飽和橡膠并用難,自粘和互粘性都很差,故加工性能不好。

三元乙丙膠3745P

根據乙丙橡膠的性能特點,主要應用于要求耐老化、耐水、耐腐蝕、電氣絕緣幾個領域,如用于輪胎的淺色胎側、耐熱運輸帶、電纜、電線、防腐襯里、密封墊圈、建筑防水片材、門窗密封條、家用電器配件、塑料改性等。

性質用途:

乙丙橡膠以乙烯和丙烯為主要原材料合成,耐老化、電絕緣性能和耐臭氧發能突出。乙丙橡膠可大量充油和填充碳黑,制品價格較低,乙丙橡膠化學穩定性好,耐磨性、彈性、耐油性和丁苯橡膠接近。乙丙橡膠的用途十分廣泛,可以作為輪胎側、膠條和內胎以及汽車的零部件,還可以作電線、電纜包皮及高壓、超高壓絕緣材料。還可制造及鞋、衛生用品等淺色制品。工業上通常說的本色是指黑色。
