The zbd-004 product is one kind of high density polyethylene tubing class special-purpose nanometer parent material. In the tubing product, may play to the inorganic enhancement, the plasticizing role, has the suitable thermostability, the dispersivity, the thermal stability, but remarkably strengthens the thin film class product the longitudinal strength, the yield strength, the break elongation ratio and the anti- aged performance. The parent material compatibility is good, may improve the product system to change the performance, enable the product to have the good size stability. Product superficial diaphaneity good, in the production the dust floats few, the workability is superior, not only may large scale reduce the product production cost, but also may promote the product quality. May act according to the customer request appropriate readjustment different melt body speed.
