高韧性 耐酸 食品级 PSU 牙齿应用 Udel P-3500 NT LCD

产品说明: Udel P-3500 LCD是一种分子量极高的聚砜,在现有的可供牌号中具有最高的韧性和耐化学性。非常适用于挤塑。 Udel P-3500 LCD的优点源自于其较低水平的环状二聚体聚合物。 聚砜是一种高韧度、高刚性和透明的高强度热塑性塑料,适合在高达300 ° F(149 ° C)的温度下长期使用 。抗氧化、抗水解,可长时间暴露于高温环境,并可进行反复灭菌。 聚砜耐无机酸、碱、盐溶液、洗涤剂和碳氢油类物质。应避免与极性溶剂如酮、氯化烃类和芳族烃接触,因为这些类型的化合物容易引起应力开裂或聚砜树脂溶解。 聚砜能很好地耐受伽马射线或电子束辐射降解,但长期暴露于紫外线下会受到不利影响。在很宽的温度范围内、在水中浸泡后或暴露于高度潮湿的环境下,具有很稳定的电气性能。 该树脂与食品接触非常安全。符合FDA 21 CFR 177 、1655标准,可用于与食品接触的重复使用物品。此外,符合NSF、美国农业部肉类和家禽接触,及奶业协会3 -A卫生标准。 - 透明: Udel P-3500 NT LCD

高清晰度 蒸汽灭菌性 医疗/保健应用 Udel M-2300 MR 美国索尔维 PSU

产品说明: Udel M-2300 MR is an injection-moldable, low-color grade of polysulfone that is nearly water white in color. This material contains a mold release which aids part ejection when parts with low draft are injection molded. Polysulfones have long been known for transparency and clarity, but have been somewhat limited by a slight yellow cast which has been typical of the material. These grades were designed to eliminate the yellow cast and provide improved aesthetics for applications where a yellow cast is undesirable. In general, Udel polysulfone is a tough, rigid, high-strength, high-heat thermoplastic that retains its properties at temperatures from -101°C to 149°C (-150°F to 300°F). With a heat deflection temperature at 1.8 MPa (264 psi) of 174°C (345°F) and excellent thermal and oxidative stability, this resin is suitable for sustained use at temperatures up to 149°C (300°F). Other key properties of polysulfone include resistance to hydrolysis by hot water and resistance to acids and bases. In addition, the resin is resistant to a wide range of cleaners and disinfectants. Polysulfone's resistance to alcohols and aliphatic hydrocarbons is also good; however, the resin is generally not resistant to polar organic or chlorinated solvents. Udel M-2300 NT MR also offers superior retention of properties after repeated steam sterlizations. - Natural/Transparent: Udel M-2300 NT MR Features: Acid Resistant; Alcohol Resistant; Alkali Resistant; Cleanable; Good Chemical Resistance; Good Sterilizability; Good Surface Finish; Good Toughness; High Clarity; High Heat Resistance; Hydrocarbon Resistant; Hydrolytically Stable; Steam Sterilizable Uses: Medical/Healthcare Applications

食品接触级 蒸汽灭菌性 医疗护理用品应用 Udel P-3500 NT 11 美国索尔维 PSU

产品描述 Udel® polysulfone is a tough, rigid, high-strength thermoplastic with outstanding hydrolytic resistance. Udel® P-3500 LCD MB series polymers are particularly well suited for the fabrication of porous hollow fiber and flat sheet membranes using a solvent-based process. These high molecular weight polymers are used in a variety of membrane filtration applications, such as renal dialysis, water treatment, bio-processing, food and beverage processing, and industrial gas separation. Udel® polysulfone polymers possess a number of attributes that are valued by the membrane industry, including excellent mechanical properties, stability at pH levels from 2-13, excellent resistance to caustic and good resistance to moderate concentrations of chlorine. They feature low levels of extractible and insoluble materials making them suitable for drinking water and food contact uses. They may be sterilized using steam, ethylene oxide and e-beam radiation. Udel® P-3500 is soluble in commercially available, water-miscible, dipolar, aprotic solvents, such as dimethylacetamide (DMAC), dimethylformamide (DMF), and N-methylpyrrolidone (NMP). These materials offer membrane producers very good control of pore size and pore size distribution, high membrane strength, and good film-forming properties.

耐酒精 耐化学性 电器用具应用 Udel P-3703 NT 11 美国索尔维 PSU

产品说明: Udel® P-3703 is a high-flow grade of polysulfone intended for injection molding applications with thin walls or long flow lengths. This grade has higher flow than Udel® P-1700 and a slightly greater tendency to stress crack in some aggressive environments. Udel® polysulfone is a tough, rigid, high-strength thermoplastic that maintains its properties at temperatures from -101°C to 149°C (-150°F to 300°F). The heat deflection temperature at 1.8 MPa (264 psi) is 174°C (345°F). For most purposes, this resin is suitable for continuous use up to 149°C (300°F). The material is resistant to oxidation and hydrolysis and withstands prolonged exposure to high temperatures and repeated sterilization. Udel polysulfone is highly resistant to mineral acids, alkali and salt solutions. The resistance to detergents and hydrocarbon oils is good, but it will be attacked by polar solvents such as ketones, chlorinated hydrocarbons and aromatic hydrocarbons. Electrical properties of Udel polysulfone are stable over a wide temperature range and after immersion in water or exposure to high humidity. Natural: Udel® P-3703 NT 11
