Polyglue® LE149V
LLDPE
现代工程塑料(Hyundai)
产品描述
LE149V is a polyethylene based adhesive polymer containing anhydride functionality. It is available in pellet form and designed for use in 3-layer pipe coating systems in conjunction with an epoxy primer and a thick polyethylene top-coat. LE149V has high physical properties originated from LLDPE and shows excellent processability during 3-layer pipe coating operation. Together with ET509B (Black compounded top coat) and commercially available epoxy primer, LE149V shows highly adjusted pipe coating system available for all pipe coating specification including DIN30670, CSA Z425.21-02, NFA 49-710.
