Nano enhanced serise of filler masterbatch production has changed the traditional production technology.The nano production technology used the special additive to conduct and disperse the material,enhanced the adhesion strength of the fillers and the matrix resin in large length to diameter ratio and high mixing effect of twin screw extruder,finall manufactured the granulation form-ing products.Production practice has proved that using nanometer reinforced filler masterbatch can reduce production cost improve product performance,and enhance product market competition ability,this,will surely bring great economic benefits of enterprise.Masterbatch can be widely used in large diameter bound to burn to burn pipe,corrugated pipe,pipe,perforated pipe,packing belt,braided belt,hollow blow molding products,plank,and plastic injection products,etc..the adding amount is 10%-40%.
