Unitem聚醚酰亚胺(PEI)是一种由SABIC Innovative Plastics的Ultem树脂制成的无定形热塑性塑料。Unitem-Pei非常坚硬,尺寸稳定,能够承受340°F的连续工作温度。由于其具有优异的抗高压灭菌能力,并且符合FDA/USDA标准,因此Unitem-Pei通常被指定用于医疗和制药行业中使用的可重复使用的机加工部件。这种材料还为电子和半导体设计人员提供了无与伦比的介电性能,可以在较宽的频率范围内保持。未填充的Unitem Pei为深琥珀色,半透明。对于需要提高刚度的应用,玻璃纤维填充等级为10%-40%。Nytef Plastics的Unitem-Pei库存形状为UL V-0级,可提供各种大规格杆、板和管状杆尺寸。产品属性340°F连续使用温度半透明,淡琥珀色,强度和刚度优异,即使在高温下,低吸湿性,优异的电气性能,额定值为UL V-0,易于加工和制造FDA,符合美国农业部标准的玻璃纤维填充等级,用于改善强度和刚度行业。医用和制药飞机及航空航天流体处理电气和电子制造微波通信应用视窗玻璃管汇电绝缘体电气元件外壳飞机仪表 UNITEM Polyetherimide (PEI) is an amorphous thermoplastic that is manufactured from SABIC Innovative Plastics' ULTEM resin. UNITEM PEI is extremely rigid, dimensionally stable, and able to withstand continuous operating temperatures of 340°F. Because it offers superior resistance to autoclave sanitizing and is FDA/USDA compliant, UNITEM PEI is routinely specified for reusable machined components used in the medical and pharmaceutical industries. This material also offers electronic and semiconductor designers unmatched dielectric properties that are maintained over a wide frequency range. Unfilled UNITEM PEI is dark amber in color and semi-transparent. For applications that require improved stiffness, glass fiber filled grades with filler levels of 10%-40% are available. Nytef Plastics' UNITEM PEI stock shapes are UL V-0 rated and available in a full range of heavy gauge rod, plate and tubular bar sizes. PRODUCT ATTRIBUTES 340°F continuous use temperature Semi-transparent with light amber color Excellent strength and rigidity, even at elevated temperatures Low moisture absorption Superior electrical properties Rated UL V-0 Easily machined and fabricated FDA, USDA compliant Glass fiber filled grades for improved strength and stiffness INDUSTRIES Medical and pharmaceutical Aircraft and aerospace Fluid handling Electrical and electronics manufacturing Microwave communications APPLICATIONS Sight glasses Manifolds Electrical insulators Electrical component housings Aircraft instrumentation |
