(1) Material: reinforced nylon, with high pressure and tensile load, good toughness, high flexibility and wear resistance, flame retardant, high and low temperature performance and stability, can be used in the outdoors, the number of nylon determines the drag The use of the chain strength and wear resistance and the size of the noise running. Nylon content ranging from 5% -17%, but the super but 19%.Generally about 30% of the content.
(2) resistance to resistance: oil, salt, and a certain acid and alkali resistance.
(3) running speed and acceleration (specific speed, acceleration depending on the operation may be).
(4) operating life.
(5) to see the structure not only in the mechanical back to the role, but also look at the appearance.
