They are polytetrafluoroethylene, polyvinylidene fluoride and polyvinyl fluoride.

分别是聚四氟乙烯、聚偏二氟乙烯和聚氟乙烯。

In order to ensure that the connections do not leak, often with the lead oil, hemp, and PTFE wire filled with raw materials; of these raw materials PTFE tape, use growing a wide range; corrosion resistance of this material can be a very good sealing effect a very good, easy use and storage, demolition, you can be completely removed, because it is a layer of non-sticky film, more than lead oil, hemp line is much more superior.

为了确保连接处不漏，往往用铅油、线麻和聚四氟乙烯生料带填充；其中聚四氟乙烯生料带，使用日见广泛；这种材料耐腐蚀性能很好，密封效果极佳，使用和保存方便，拆卸时，可以完整地将其取下，因为它是一层无粘性的薄膜，比铅油、线麻优越得多。

Micro-structures of latexes were studied and components of the core and the shell were discussed, then the forming mechanism was analyzed.

采用外来种子乳液聚合方法，用反应单体对外来种子聚四氟乙烯乳液进行浸泡、溶胀，然后引发聚合反应制得聚四氟乙烯改性的聚丙烯酸酯乳液。

In the subatmospheric pressure system,the preparation of tetrafluoroethylene monomer by pyrolyzing waste polytetrafluoroethylene was studied.

在负压系统中，采用真空热裂解法裂解废聚四氟乙烯塑料，对四氟乙烯单体生产工艺进行研究。

PTFE is a typical low-surface-energy material: The CA for water on a smooth PTFE film is about 121.61.88, and for diesel oil it is 11.21.68, that is, PTFE is intrinsically hydrophobic and oleophilic.

聚四氟乙烯是一种典型的低表面能材料：核证机关水在光滑的PTFE膜约121.6？1.88，和柴油是11.2？1.68，也就是说，聚四氟乙烯在本质上是疏水性和亲油性。

The main products are SF-1 (as the base plate of the middle sintering Copper Balls powder, surface modified PTFE); SF-2 (plate as the base of the middle sintering Copper Balls powder, surface modified POM); JDB (For brass, bronze, iron-based body, inlaid solid lubricant); dual-metal (steel as the base for the various models of the surface of copper); production of various enterprises have also filled with PTFE, the curve of bearings, bearing powder metallurgy, by Chun-for the Pistons, Piston Ring, ethylene tetrafluoroethylene ring, ring.
