During the recent 50 years’ experience of using Poly Tetra Fluor Ethylene (PTFE) – Fluor plastic 4 – in industry it were many different approaches to modify it. Among others we should highlight copolymerization as the main one that represents adding extrinsic molecular groups into polymer network as well as physical mixing with different agents that makes stronger or armed molecular matrix. Such approaches allowed achieve serious results. However, their limit has been reached today and traditional approaches are over. Different variation of PTFE mixed with coke, optical fiber, carbon fiber, graphite with metal oxide and recently nano-dimensional elements with different activation methods have little difference among them. For example, for durability it is inside ten percent variation.
Therefore, achieved limit for dimensionless quantity of relative linear wearing during friction without lube is (0,5—1,0) Х10-7 micron/km.
It was hard to expect that a new modification method will be discovered in order to fix the disadvantages of PTFE while maintaining its advantages and universalities.
However, such method has appeared recently. Moreover, the results were even higher than expected: abrasion durability of the new PTFE modification has been increased for more than four dimensions and achieved during a friction without a lube (0,1 –0,3)х10-8 micron/km. The viscous and radiation resistance have been improved on one to two dimensions as well. In compare with the best composite materials the effect is 10 – 50 times better. In addition to that a friction coefficient even reduced. And chemical and biological resistance as well as low surface power and dialectical properties are unchanged as in original PTFE. The new technology is entirely based on material nano-structure modification. And the nano-structuring processes are playing the main role there. RAFLON is a name of the new material.
