Baydul® 665 IBS是一种用于反应注射成型(RIM)工艺的黑色、硬质聚氨酯结构泡沫体系。该系统包括一个专门设计的交互式吹扫系统(IBS),作为两个反应性液体成分提供。A组分为聚合物二苯基甲烷二异氰酸酯(PMDI),B组分为不含CFC-或HCFC发泡添加剂的配方多元醇体系。注意:由于可能存在颜料沉淀,在将桶内物质输送至日计量箱之前,应彻底搅动成分B。Baydur 665 IBS系统用于一般用途的应用,要求注射时间超过10秒。这些应用通常存在于建筑、家具和运输市场,利用了材料的强度以及其优良的表面光洁度、大部件性能和良好的流动性。与任何产品一样,在给定应用中使用Baydur 665 IBS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 665 IBS is a black-pigmented, rigid polyurethane structural foam system used in the reaction injection molding (RIM) process. This system incorporates a specially engineered interactive blowing system (IBS) and is supplied as two reactive liquid components. Component A is a polymeric diphenylmethane diisocyanate (PMDI), and Component B is a formulated polyol system containing no CFC- or HCFC-blowing additives. Note: Component B should be agitated thoroughly prior to delivery of drum contents to day tank due to possible pigment settling. The Baydur 665 IBS system is used for general-purpose applications that require injection times longer than 10 seconds. The applications, typically found in the construction, furniture, and transportation markets, take advantage of the material's strength as well as its excellent surface finish, large part capability, and good flowability. As with any product, use of the Baydur 665 IBS system in a given application must be tested (including field testing, etc.) in advance by the user to determine suitability. |
