  • Nano is the statutory measurement in the name of the measuring unit, its unit symbols is nm. 1nm equal to one thousand millionth of a meter, namely as long as 10 hydrogen atoms in straight line. When the particle size of the material is 0.1-100nm, collectively called nanophase materials. At present the nanometer material in plastic can improve the material’s barrier property, the mechanical strength, thermal deformation temperature and improve the material’s low temperature resistance, at the same time , strengthened the antioxidant brittle relaxing and ultraviolet prevention ability, greatly improve the service life of the pipe.
