        Character:
	白色微粉状树脂,是由四氟乙烯经调聚反应得到的分散液再经凝聚、洗涤、干燥而制得,具有优良的耐热性、耐候性、耐寒性、低摩擦性、不粘性、化学稳定性和电绝缘性能等优异性能。另外由于其平均粒径小,所以具有很好的分散性,容易均匀地与其他材料共混。   聚四氟乙烯微粉有较大的比表面,易吸潮,使用前宜将FR002A在小于150℃温度下干燥。为了保持良好的分散性,必须避免使粉末产生粘结的各种情况。
加工时要小心处理,避免加热到300℃以上。
        Quality Standard:	外观           白色微粉
体积密度(g/l)      400
平均粒径(μm)       5
比表面(m2/g)       10
熔点(℃)         327
含水率(%)        0.04
注:以上数据为典型值。
 
        Storage:
	易吸潮,密封保存
聚四氟乙烯微粉可以单独作固体润滑剂使用,也可以作为塑料、橡胶、涂料、
油墨、润滑油、润滑脂等的添加剂。
  与塑料或橡胶混合时可用各种典型的粉末加工方法,如共混等,聚四氟乙烯微粉加入量为5~20%,在油和油脂中添加聚四氟乙烯微粉,可降低摩擦系数,只要加百分之几,就可提高润滑油的寿命。
  聚四氟乙烯微粉的有机溶剂分散液还可作脱模剂。
