EPDM胶条
耐候性
耐温性
耐水性
作为耐天候性能标杆,EPDM 胶条以其卓越的耐臭氧、耐紫外线和耐热氧化性能著称,能在 - 40℃至 120℃的宽广温度范围内保持优异弹性与压缩恢复性。它广泛用于对长期户外耐久性要求极高的领域,如汽车门窗密封条和建筑幕墙密封,是应对风吹日晒的核心优选材料,使用寿命可达数十年。
Key Advantages:

优异的耐候性:在户外长期暴露(日晒雨淋、臭氧)下,物理性能变化极小,不易龟裂、变硬或失去弹性,使用寿命可达数十年。
宽广的耐温性:一般可在-40℃至120℃(短期可达150℃)环境下稳定工作。
良好的耐水性、耐化学性:对水、热水、水蒸气、弱酸弱碱、洗涤剂等有很好的抵抗力。
优异的弹性与压缩永 久变形性能:回弹性好,密封持久。

Applications

Automotive: Door/window seals, trunk seals, engine hood seals.

Construction: Curtain wall joints, window seals, roofing membranes.
