涂料方面，在涂料中加入5‰—3%的PTFE微粉，可以明显改善涂料黏性及润滑性，降低摩擦系数并提高耐磨性、耐腐蚀性、耐划伤性、耐涂鸦性并减少吸潮，改善涂料的喷射浇铸性能，提高临界膜厚度并改善其热成型性能等。
**涂料主要应用类别——粉末涂料、油性涂料、水性涂料。
油墨方面，在油墨中加入0.1%—3%的PTFE微粉，可以明显改善油墨的滑动性、表面光滑性、光泽、并使印刷产品耐摩擦，适用于快速打印机的需求，可以减少堵塞，还能有效地避免纸张黏结。
**油墨——胶版印刷、凹版印刷、柔性印刷、丝网印刷等。
石墨烯方面，添加聚四氟乙烯（PTFE）微粉后的石墨烯聚合物，除了拥有PTFE微粉(耐腐蚀、耐高（低）温、耐老化、高绝缘、高润滑，不黏附)和石墨烯（增韧、导电、散热效果）的优良特性外，还具有良好的防静电性能。
