<1> The application of MC nylon
MC nylon uses widely in the project plastic at now, particularly in the machine aspect for reducing bearing whetting aterial to replace alloy and copper material .
1,The machine strength is high, the tenacity is big, the bearing to whet is good, the fusion point is high, and bear the oil, bear the eclipse, bear the water.
2,The size stability is good, can lubricant itself and is not restricted by its size.
3,The cost is low, the life span is long, and the cost is only for metals’s 50%-70%, life span is general longer 2-3 times than metal’s.The use of MC nylon is very wide, such as turbine, wheel gear, silk pole etc on the machine
