NBR

      耐磨性、抗透氣性和耐油性好，適用于礦物液壓油、潤滑脂、硅油、阻燃液和80℃的熱水中。不適用于極性溶劑、剎車液。耐臭氧性、耐侯性一般，但因一般密封件是安裝于油缸內(nèi)而不會受此影響。             
Good mechanical technological parameters,e.g. high abrasion resistance, low gas permeability and good resistance to mineral oil based lubricating oils and greases, hydraulic oils,highlynon-flammable hydraulic fluids HFA, HFB, HFC, silicone oils and greases, water up to approx. 80°C.NBR is generally not resistant to polar solvents, glycol-based brake fluids and highly non-flammable hydraulic fluids HFD. It has a low resistance to ozone, weathering and ageing. In most hydraulic applications this has no effect because the hydraulicseals are installed internally in the hydraulic components.

PTFE display almost universal chemical resistance,an extremely low friction value which results in very good sliding characteristics, no stick-slip effect,particular rigidity and almost unlimited ozone, weathering and ageing resistance. PTFE is impervious to almost all known hydraulic media, lubricants,chemicals and solvents.PTFE is non-flammable and so does not constitute an additional hazard in case of fire.Pure PTFE is not totally without disadvantages as it has a tendency to cold flow or crawl under pressure load.These weaknesses are counteracted by the use of seal compounds mixed with fillers.

Pure PTFE is particularly suitable for food and
beverage applications, pharmaceuticals and
medical application areas. PTFE is not or only
slightly elastic. For this reason, PTFE seal
elements are activated by elastic energising
elements in the form of o-rings or stainless steel springs.  Compounds filled with bronze for example, give PTFE the ability to adapt to most application conditions.
