style="text-indent:25px">上海偉奮實(shí)業(yè)有限公司環(huán)氧板獲得眾多用戶的認(rèn)可。上海加工環(huán)氧板廠家哪家好</p><p> 上海偉奮實(shí)業(yè)有限公司，環(huán)氧樹脂板又叫絕緣板、環(huán)氧板、3240環(huán)氧板，特點(diǎn)是粘附力強(qiáng)、收縮性強(qiáng)。 </p> <p> 環(huán)氧樹脂是泛指分子中含有兩個(gè)或兩個(gè)以上環(huán)氧基團(tuán)的有機(jī)高分子化合物，除個(gè)別外，它們的相對(duì)分子質(zhì)量都不高。環(huán)氧樹脂的分子結(jié)構(gòu)是以分子鏈中含有活潑的環(huán)氧基團(tuán)為其特征，環(huán)氧基團(tuán)可以位于分子鏈的末端、中間或成環(huán)狀結(jié)構(gòu)。由于分子結(jié)構(gòu)中含有活潑的環(huán)氧基團(tuán)，使它們可與多種類型的固化劑發(fā)生交聯(lián)反應(yīng)而形成不溶、不熔的具有三向網(wǎng)狀結(jié)構(gòu)的高聚物。上海加工環(huán)氧板廠家哪家好</p><p
