Baydur 426 IMR是一种聚氨酯高密度结构轮辋(HD SRIM)系统,用于汽车和轻型卡车应用。该系统适用于载重汽车道床、尾门、保险杠梁、载重地板等,具有良好的热稳定性。Baydur 426 IMR复合材料可用于替代钢或结构塑料,从而显著减轻重量,降低加工成本。由于其固有特性,该系统具有抗腐蚀和耐磨性。Baydur 426 IMR系统可以采用闭式模具或开放式模具进行加工。该系统与多种玻璃增强材料结合,制成结构复合材料。玻璃纤维垫、定向切割预制件或玻璃粗纱可用于加固。该系统具有合适的反应速度,可用于玻璃纤维切边机。BaydUR 426 IMR系统具有非常长的凝胶时间,但快速固化时间,这使得它非常适合大型汽车部件。Baydur 426 IMR系统作为两种反应性液体成分提供。A组分为聚合物二苯基乙烷二异氰酸酯(PMDI),B组分为配制的聚醚多元醇体系。与任何产品一样,在给定应用中使用Baydur 426 IMR系统必须由用户提前进行测试(包括现场测试等),以确定适用性。 Baydur 426 IMR is a polyurethane high density structural RIM (HD SRIM) system used for automotive and light truck applications. This system is well suited for load bearing truck beds, tailgates, bumper beams, load floors, etc. It has excellent heat stability performance. Baydur 426 IMR composites can be used to replace steel or structural plastics for significant weight reduction ad lower tooling costs. Due to its inherent nature, this system is corrosion and abrasion resistant. The Baydur 426 IMR system can be processed with either a closed mold or open mold. This system is combined with a variety of glass reinforcements to make a structural composite. Glass mats, directed chop preforms or glass rovings can be used for reinforcement. This system has the appropriate reaction rate so that it can be used with a chopped glass fiber RIM machine. The Baydur 426 IMR system has an exceptionally long gel time, yet fast cure time, that makes it well suited for large automotive parts. The Baydur 426 IMR system is supplied as two reactive liquid components. Component A is a polymeric diphenlymethane diisocyanate (PMDI), and Component B is a formulated polyether polyol system. As with any product, use of the Baydur 426 IMR system in a given application must be tested (including field-testing, etc.) in advance by the user to determine suitability. |
