Kraton G1641 H是一种透明的线性三嵌段共聚物,以苯乙烯和乙烯/丁烯为基础,聚苯乙烯含量为33%。它由北美提供,其物理形式如下所示。Kraton G1641 Hu-作为未经抛光的粉末Kraton G1641 HS-作为粉末Kraton G1641 H提供,用于化合物配方和热塑性塑料的改性剂。它也可用于配制粘合剂、密封剂、涂料和改性沥青。 Partially hydrolysed grade Mowiol® and Kuraray Poval® are the trade name of the polyvinyl alcohols marketed by Kuraray. These are manufactured from polyvinyl acetate by alcoholysis using a continuous process. By varying the degree of polymerization of the polyvinyl acetate and its degree of hydrolysis (saponification), a number of different grades can be supplied. Our PVOH types are offered in a high standard purity showing especially "low ash and VOC contents". |
