牌号简介	Baydul- 728 IBS是一种用于反应注射成型（RIM）工艺的高密度聚氨酯结构泡沫体系。该系统包括一个专门设计的互动吹制系统（IBS）和内部模具释放（IMR）。该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。Baydur 728 IBS系统用于需要UL94可燃性等级为V-0和/或5VA的应用，用于电子、设备外壳和电器市场。这些应用通常利用了材料的强度、优异的表面光洁度和大零件性能。与任何产品一样，在给定应用中使用Baydur 728 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 728 IBS is a high-density polyurethane structural foam system used in the reaction injection molding (RIM) process. This system incorporates a specially engineered interactive blowing system (IBS) and internal mold release (IMR). The system 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. Baydur 728 IBS system is used in applications requiring a UL94 flammability rating of V-0 and/or 5VA for use in electronic, equipment housing, and appliance markets. The applications typically take advantage of the material's strength, excellent surface finish, and large-part capability. As with any product, use of the Baydur 728 IBS system in a given application must be tested (including field testing, etc.) in advance by the user to determine suitability.
