| Material / type材质 / 类型 | Typical use典型用途 | Typical temperature参考温度 |
|---|---|---|
| Virgin PTFE纯四氟(未填充) | Chemical, food and pharma contact, electrical insulation化工、食品医药接触、电气绝缘 | ≈ -200 to 260 °C |
| Glass-filled PTFE玻纤填充四氟 | Higher wear and creep resistance, seals and bearings更耐磨、抗蠕变,密封件和轴承 | ≈ up to 260 °C |
| Carbon / graphite-filled PTFE碳 / 石墨填充四氟 | Dry running, low friction, pump rings干运转、低摩擦、泵用环件 | ≈ up to 260 °C |
| Bronze / MoS2-filled PTFE青铜 / 二硫化钼填充四氟 | High load, piston rings and guide strips高载荷、活塞环及导向环 | ≈ up to 260 °C |
| Expanded PTFE (ePTFE) tape / sheet膨体四氟带 / 板 | Flange sealing on glass-lined or uneven flanges搪玻璃及不平整法兰密封 | ≈ -240 to 260 °C |
Temperature figures are typical industry reference values and depend on grade and design. We confirm the right material for your actual conditions when quoting.温度数据为行业常见参考值,具体取决于牌号和结构。报价时我们会按您的实际工况确认材质。

Form (sheet, rod, tube, film, gasket or machined part), dimensions and thickness, filler type if any, drawing for machined parts, quantity产品形态(板、棒、管、膜、垫片或加工件)、尺寸及厚度、是否需要填充、加工件图纸、数量
Yes. Send the drawing with tolerances and material requirement and we will quote machined parts.可以。请提供带公差和材料要求的图纸,我们报价加工件。
Virgin PTFE has the best chemical purity; fillers such as glass or carbon improve wear and creep resistance but slightly reduce chemical purity.纯四氟化学纯净度最好;玻纤、碳等填料提高耐磨与抗蠕变,但会略降低纯度。
