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。
Chemours Teflon® PTFE 850A Granular Molding Powder
PTFE
Chemours
产品说明：
Teflon® PTFE white granular molding powders are ideal for molding many different end products and stock shapes. Excellent chemical resistance, electrical properties, high temperature performance, low temperature toughness, plus unique adhesion and flame resistance.
Teflon® PTFE granular molding powders are processed by compressing them into a desired shape and heating them at temperatures above their melting point to consolidate the powder.
Resin Characteristics: Improved free-flow pellets with high bulk density. Excellent handling resin. Uses: Automatic molding of small-to-medium-sized parts; lined pipes, valves, and fittings via isostatic molding; compression molding of sheets.
Typical properties for Teflon® PTFE Granular Resin:
Chemours was formed from former DuPont performance chemicals businesses, including DuPont Fluoroproducts, in 2015.
