产品描述
High density polyethylene for 3-layer PE coating(Black Compound) - Top Coat
ET509B is a black, high-density polyethylene produced with Sclairtech technology. It is well modified by melt blending to meet the requirements of globla standards and standards of customers' own. It is designed for use as a top-coat in 3-layer pipe coating systems with conventional grafted adhesive (Polyglue LE149V, LE200T, LE100A and LE851P etc). Base PE of ET509B has high physical properties originated from HDPE and blended resins improve ESCR, impact properties and processibility. Together with Polyglue grades for 3-layer PE, ET509B shows highly adjusted pipe coating system available for all pipe coating specification including DIN30670, CSA Z425.21-02, NFA 49-710.
