聚四氟乙烯（PTFE）微粉—B01，粒径12微米左右，不仅保持了PTFE原有的优良性能，而且还具有分散性好、易于与其他材料均匀混合等优点，广泛应用于合成材料的共性，可以提高基材的润滑性、耐磨性、不粘性和阻燃性，此外还可以作为橡胶、金刚石、砂轮、刹车片、酚醛树脂等的添加剂。

在合成材料方面，PTFE微粉—B01可用作合成材料的改性剂。据报道，目前市场上具有改进的润滑性能的工程塑料很多都掺加了PTFE微粉。例如，在聚酰胺(PA)、聚缩醛(POM)、聚碳酸酯(PC)、丙烯晴—丁二烯—苯乙烯共聚物(ABS)、聚丙烯（PP）聚对苯二甲酸丁二酯（PBT）、聚对苯二甲酸乙二酯（PET）…和其他高性能工程树脂中加入5%—15%的PTFE微粉，就能改善这些材料所制备的零件的磨耗、摩擦性和黏性滑动等性能，可用于制造齿轮、轴承和滑轮等，也可用来代替起润滑作用的金属部件，减少制件的重量和降低维修成本。

橡胶方面，PTFE微粉—B01可提高橡胶表面性能和体积性能，如在有机硅橡胶、丁晴橡胶、氟橡胶、三元乙丙橡胶和聚氯丁二烯等中加入5%-8%（质量分数）的PTFE微粉，可以提高主体聚合物的摩擦性能、磨损性能和脱模行为，提高橡胶的破碎强度，而橡胶的弹性行为无明显破坏，这就可以减少橡胶在脱模过程中造成的撕裂现象。

砂轮方面，加入聚四氟乙烯（PTFE）微粉—B01制成的砂轮，PTFE会以粉末形式分布在砂轮里面，当砂轮被磨损时，PTFE粉末脱离砂轮，形成一种耐高温并耐磨润滑剂的作用。因而能改善砂轮的耐磨损性能。另外，加入聚四氟乙烯粉末，也可以一定程度增加砂轮的韧性，降低刚性，从而在使用中减少砂轮发脆现象。

金刚石方面，聚四氟乙烯（PTFE）微粉—B01作为金刚石材料添加剂，采用一系列方法与金刚石粉末结合，制备出的金刚石制品摩擦系数降低，其摩擦磨损性能提高。
