塑料公司推出非晶体聚合物系列产品

一种非晶体聚合物具有良好的性能,而无半晶体材料和亚醯化热固树脂的各种缺点。

聚合物的研制并非一日之功,有时甚至需要10余年的努力。对于GE塑料公司(广州; www.geplastics.com)来说,距离上次推出新聚合物系列产品,已经将近20年了。但是,耐心的等待终于有了回报,经过13年的研发,一种可耐受极高温度的非晶体热塑聚酰亚胺问世了。

据GE公司介绍,Extem高性能聚合物平台具有良好的耐高温性和耐化学腐蚀性,而且没有半晶体材料、亚醯化热固树脂和其他竞争性非晶体热塑塑料的各种缺点。该聚合物可用于血液相容性薄膜及无创手术和实验室用品等医疗领域。

GE塑料公司高性能聚合物部总经理Brian Herington说: 到目前为止,客户如果需要超高性能塑料,只能在价格昂贵、加工成本高的亚醯化热固树脂与高性能半晶体树脂间进行选择。Extem树脂可解决这些难题,它具有极佳的性能,加工成本低,而且无需注塑后固化或结晶等后续操作。"

这种树脂不但可免除后续操作的步骤,而且熔融加工灵活,适合各种常规处理技术。材料经注塑、挤出、焊接、机械加工或热成型后仍可保持原有特性。此外,Extem树脂还可在传统挤出和注塑设备上进行熔融加工。

该产品在零度以下、200C以上的温度范围内均可保持尺寸稳定,而且不需添加卤素添加剂(目前认为使用卤素可能引起危险),本身即具有阻燃性。此外,该树脂具有高达310C的玻璃转化温度,并且对含氯溶剂具有极高的非晶体耐化学腐蚀性。在高温、负荷的情况下,材料还具有硬度大、抗蠕变性强等优点。

Extem热塑聚酰亚胺的基本结构是由具有专利的单体组成的新型分子。研发出这些单体时,公司意识到需要一家专业生产Extem树脂的工厂。为了提供树脂生产所需的新型聚合工艺,公司投资了3000万美元扩建其位于美国印地安那州的工厂。 此外,公司还在西班牙Cartagena新建了一家加工Extem树脂的工厂。
