用途：

玻璃纤维涂层的聚四氟乙烯高温布因其优异的性能而广泛用于航空，造纸，食品，环保，印染，服装，化工，玻璃，医药，电子，绝缘，建筑（屋顶膜结构基布），砂轮切片，机械等领域。可用作加热食品的防腐涂料，内衬和垫片，防粘输送带，高频覆铜箔层压板，建筑膜材料，绝缘材料，微波干燥输送带，柔性补偿器，摩擦材料等。垫片，烤盘等，微波垫片，微波干燥带。塑料，橡胶，防粘衬里，垫片，覆盖物等，地毯胶带应用等。根据厚度的不同，它可用于各种干燥机的输送带，例如干燥药用材料，茶叶，食品，化学品，用于各种石油化工管道，电子电器绝缘，耐温涂料，发电厂废气的环保脱硫等的防腐涂料等的胶带，密封带等。

特点：

聚四氟乙烯高温布用于低温-196℃和高温300℃之间。具有耐候性和抗老化性。实际应用后，如果在250℃下连续放置200天，不仅强度不会降低，重量也不会降低。在350℃下放置120小时，重量仅减少0.6％。在-180℃下，超低温下不会出现裂纹，并保持原有的柔软性。具有非粘性：不容易粘附任何物质。易于清洁附着在其表面的各种油渍，污渍或其他附件；几乎所有的粘性物质，例如糊剂，树脂，油漆，都可以轻松清除；耐化学腐蚀，强酸，强碱，各种有机溶剂腐蚀。低摩擦系数（0.05-0.1），是无油自润滑的最佳选择。透光率为6-13％。它具有较高的绝缘性能（较小的介电常数：2.6，切线低于0.0025），抗紫外线，抗静电。尺寸稳定性好（伸长率小于5‰），强度高。具有良好的机械性能。耐药且无毒。
