发泡剂H

发泡剂H用途

1.该品为应用广泛的发泡剂之一，主要用于制造海绵橡胶，在塑料中多用于聚氯乙烯。该品加热分解成氮气而致孔，发气量大，不泡效率高。使用水杨酸、己二酸、邻苯二甲酸等有机酸或尿素作发泡助剂，可降低分解温度，调节在90-130℃的范围内。该品分解时的发热量大，因而易使厚制品的中心部位炭化，而且分解产物有恶臭。与尿素并用可消除臭味。可用作聚氯乙烯及其共聚物、聚烯烃、聚苯乙烯、聚酰胺、聚酯、酚醛树脂、聚偏二氯乙烯、聚硅氧烷、聚氯丁二烯、乙烯和丙烯共聚物、聚氧化乙烯及其弹性体的发泡剂。

2.是橡胶发泡领域广泛应用的发泡剂，它具有发泡效率高、不变色、不污染等优点。可用作胶黏剂或密封剂的发泡剂。也是制造海绵橡胶及泡沫塑料的常用有机微孔发泡剂。在胶料中易分散，无污染性，但分解温度较高，分解产物有臭味。使用水杨酸、己二酸、邻苯二甲酸等作发泡助剂，可将分解温度调节在90～130℃。用尿素可消除臭味。在聚氯乙烯中用量为7%～25%，橡胶中用量为3%～5%。

3.用于橡胶、聚氯乙烯等塑料的发泡剂，制造微孔塑料。
