Teflon (PTFE, F4] is one of the best material corrosion resistance in the world today, "plastics king" laudatory name. It can be in any kind of chemical media use for a long time, it have solved our country a lot of problems in the field of chemical, petroleum, pharmaceutical, etc. Ptfe seals, gaskets, gasket, ptfe seals, gaskets, sealing washer is made from suspension polymerization ptfe resin molding processing. Ptfe compared with other plastic has the characteristics of excellent resistance to chemical corrosion and heat resistance, it has been widely used as sealing material and filler material.
PEEK and PI,new engineering plastic materials,was proven to be with the best machanical strength,dimensional stability and high temp,endurance among all the known engineering plastice.PEEK's long terms working temperature is 260℃,PI's long trem using temperature is as high as 300℃.PTFE was proven to be working under 180℃,PVDF using temp.:150℃.It is with excellent corrosion resistant,can be only dissolved or damaged by concentrated sulfuric acid,it still works under medium acid and alkali corrosive environment.Thus it is used for high precision bearing manufacturing,working under harsh environment,the only advantage is high using cost due to raw material.Generally,inner and outer ring are made of PEEK or PI,cage is made of PTFE,PEEK,PI;ZrO2 or Si3N4 ceramic balls as rolling elements.
NYLON shows good sliding property and high resistance to wear and tear because of the high strength and amooth surface.There is a very low risk of stress cracks.
Disadvantages:Not resistant to high-concertrated acids and strong oxidant. Difficult to glue and paint.
