Udel® P-3703是一种高流动级聚砜,用于薄壁或长流动长度的注塑应用。这一等级比Udel P-1700流量更高,在一些侵蚀性环境中,应力开裂的趋势稍大。udel聚砜是一种坚硬、坚硬、高强度的热塑性塑料,在-101°C至149°C(-150°F至300°F)的温度下保持其性能。1.8兆帕(264磅/平方英寸)的热变形温度为174°C(345°F)。大多数情况下,该树脂适用于149°C(300°F)的连续使用。该材料能够抵抗氧化和水解,并且能够经受长时间的高温暴露和反复灭菌。Udel聚砜对无机酸、碱和盐溶液有很强的抵抗力。耐洗涤剂和碳氢油性能良好,但会受到酮、氯化烃和芳香烃等极性溶剂的侵蚀。Udel聚砜的电性能在较宽的温度范围内,在浸水或暴露于高湿度下后是稳定的。天然:Udel® P-3703 NT 11 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 |
