The infloation free tyre id light in weight and durable in service.It is both heat and cold resistanr and excellent in elasticity.Therefore it has overcome the shortcomings inherent with the pneumastic tyre is thus the most safe and economical tyre throughout the world at present.It is widely used for such product as wheel chair car,electric motor car,ride-instead-of-walk car,hand-push carriage,baby carriage,warehousing car,carriage for the elderly,electic slide plate car,lawn mowa,golf ball car,luggage car tyre,and airport luggage car etc. It is a new generation product on the market upgarded from the pneumatic tyre.PU inflation free tyre is safe and reliable,free of servicing,and can save you from the trouble in inflating and alleviate you from the headache in air leakage. Once you get in on trouble at all throughout the service life. PU inflation free tyre has moderate hardness that is equivalent to traditional pneumatic tyre. But its rolling and braking force,shock absorption and the performance and pressure on the normal rode are superier to the corresponding penumatic tyre. A kind of material with strong polarity and polymer is used for PU inflation free tyre and is thus water,oil,dirt,acid and alkaline resistant and has little affinity with non polarity mineral oil and there is almost no way for the fuel oils(such as kerosene,gasoline),machinery oils(such as hydraulic oil,engine oil and lubricating oil) and acid and basic subatance to erode in.
