专为针罩,喷嘴帽开发的弹性体配方

最近开发的一种专利弹性材料配方,与传统的聚异戊二烯或天然橡胶弹性体相比,不易开裂,适用于制造各类针套与护帽。

West制药服务公司(美国宾州,Lionville;;www.westpharm.com)采用这种新配方生产的部件具有低核聚、低萃取物的特点,不含亚硝胺、前体物与天然橡胶,可以使用蒸汽、伽玛射线、EtO杀菌,不会像普通配方材料一样起雾或结霜。

在臭氧老化测试中,使用新型异戍橡胶改进配方的测试结果,要好于普通聚异戊二烯或天然橡胶弹性体材料。附图显示了新型材料针套(上)暴露在臭氧中2小时,天然橡胶护帽(中)暴露4分钟,及聚异戊二烯护帽(下)暴露2分钟的结果。

采用新材料生产的针套和护帽,有多种标准设计可供选择。该公司可与客户紧密合作,为客户定制部件。
