Product Details

关键性能特点:

耐化学性:与纯PTFE一致,耐强酸、强碱、有机溶剂和几乎所有化学介质(除熔融碱金属和氟气外)。
耐温性:-200°C至+260°C长期稳定使用,短期可达300°C。
低摩擦系数:0.05~0.1(静摩擦),填充后耐磨性显著提升,适合高负载摩擦场景。
绝缘性:纯PTFE为优异绝缘体,但添加碳黑/石墨可能降低体积电阻率(可制成抗静电或导电材料)。

机械性能:

- 抗压强度提高(填充后),但拉伸强度可能略低于纯PTFE。
- 抗蠕变性改善,适合长期承重部件。
其他特性:不粘性、耐候性、阻燃(UL94 V0级),且无毒(符合FDA标准,适用于食品工业)。

3. 与纯PTFE的对比优势

耐磨性:填充碳黑后,磨损率可降低至纯PTFE的1/100~1/1000。
导热性:黑色填料提升散热能力,适用于高温摩擦部件。
尺寸稳定性:减少冷流变形,适合精密机械零件。

4. 典型应用场景

工业密封:高压/高温环境下的垫片、阀座(如化工管道)。
耐磨部件:轴承、导轨、活塞环(尤其食品加工、纺织机械)。
电子/半导体:抗静电载具、绝缘垫片(需控制填料比例以平衡绝缘性)。
医疗/食品:符合卫生标准的输送带、模具衬板。

5. 注意事项

加工限制:PTFE不可熔融加工,需通过烧结成型,复杂零件需二次切削。
填充比例:过量填料可能降低耐化学性或柔韧性,需根据需求优化配方。

通过添加黑色填料,PTFE黑色板在保留化学惰性的同时,显著提升了机械和耐磨性能,扩展了其在苛刻环境中的应用范围。
