150GL30 BK短期耐热性:玻璃纤维或碳纤维增强后其热变形温度可以达到300℃以上。
长期耐热性:UL温度指数为250℃。
韧性:是一种非常柔韧的树脂。
阻燃性:达到UL94V-0级,有自熄性,燃烧时发烟量是所有树脂中***少的。
耐腐蚀性/耐***性:除浓***外无溶剂能侵蚀它。
耐热水性(可在200~300℃蒸汽中使用)。
耐疲劳及耐蠕变性(是热塑性塑料中***高的;
加工成型性:除可***成型外,还可适用各种成型方法
由于它具有高温流动性好和热分解温度很高的的特点,因此可以采用***成型,挤出成型、模压成型、吹塑成型、熔融纺丝、旋转成型、粉末喷涂等多种方法成型加工。作为二次加工可以采用真空成型、压延、拉伸、超声波焊接、粘接、复合、机械加工等加工手段。

美国苏威PEEK 150GL30 BK详解:
When an organization wants to secure its system, it must firs***termine whatrequirements to meet. Given that organizati*** normally h***e limited resourcesto protect its assets, it is equally important to determine which requirementsare more important and thus should be prioritized. To achieve this, we proposeto use a conceptual framework where security requirements are linked to theunique business drivers of the organization in question. Figure 1 portrays theconceptual framework. Business vision are high level business goals the orga-nization has. Critical Impact Factors (CIFs) identify whatwill be the businessimpacts if security requirements are violated. Valuable assets and their securityrequirements are inventories of security requirements. Valuable assets and theirsecurity requirements h***e an effect on the CIFs and the CIFs in turn impact theaccomplishment of the organization’s business vision. In other wo***, we can useorganization’s business vision to prioritize the CIFs, which further can be usedto prioritize the security requirements. To achieve that, three subsequent stepsneed to be taken. Firstly we need to enumerate valuable assets and their securityrequirements. Secondly, an organization’s CIFs and business vision need to bedefined. Thirdly, security requirements shall be linked with CIFs and businessvision. We will discuss them in detail.
