牌号简介	Adiprene Duracast S700是一种自由MDI含量较低的MDI端接聚酯预聚物。以该预聚物为原料，采用固化剂C3或C3-LF进行扩链，得到了物理性能优良的高性能70A弹性体。其他优点是改进了加工特性，在搬运过程中更容易管理健康和安全。低游离MDI预聚物的独特性能组合优于TDI和传统MDI预聚物。硬脑膜预聚物用硬脑膜C3或C3-LF固化，提供了一个优越的硬段，并提供了独特的加工和生产力的提高。这种高性能硬段具有优异的物理和工程性能，包括高抗切割和撕裂性、改进的弯曲疲劳、低温柔性、优异的动力学（低温和高温下）和其他高温性能。传统上，胺固化剂不能与MDI预聚物一起使用，因为它们具有高反应性（短的使用寿命），即使它们具有一些性能优势，如耐高温性和撕裂性能。它还提供了EH&S的优势，因为它基于低游离单体技术，是一个无MBOCA系统。 ADIPRENE DURACAST S700 is an MDI-terminated polyester prepolymer having low free MDI content. A high performance 70A elastomer with excellent physical properties is obtained when this prepolymer is chain extended with DURACURE™ C3 or C3-LF. Other advantages are improved processing characteristics and easier management of health & safety during handling. The unique combination of properties exhibited by low free MDI prepolymers is superior to those available from TDI and conventional MDI prepolymers. DURACAST prepolymers cured with DURACURE C3 or C3-LF provide a superior hard segment and offer unique processing and productivity improvements. This high performance hard segment offers excellent physical and engineering properties, including high cut and tear resistance, improved flex fatigue, low temperature flexibility, excellent dynamics (at both low and high temperatures) and other high temperature properties. Traditionally, amine cures could not be used with MDI prepolymers due to high reactivity (short pot life) even though they offer some performance advantages such as high temperature resistance and tear properties. It also offers EH&S advantages as it is based on low free monomer technology and is a MBOCA free system.
