The company produces the butyl rubber bicycle, the electric car, the cycle tube thermostablly, the production tire tube, bears the aging, gas tightness high, 180 days not to need to gasify. The tire tube tensile strength 9.0↑, elongation ratio 500↑ gas tightness is natural gum tire tube's 4 times,

fast builds up -> the mixed iron-smelting -> to build up -> filtration weighing -> Canada to press hotly -> to squeeze out -> the attachment -> curing -> inspection -> inspiration packing

 to obey the flow which strictly the tire tube produces, can satisfy the people to the tire tube gas tight request.
