SABIC® LLDPE 128CNJ
LLDPE
沙特基础 (SABIC)
产品描述
128CNJ is a Linear Low Density Polyethylene natural resin designed for extrusion applications. This grade is combining stiffness, toughness, high melt strength with an excellent processability due to its broad molecular weight distribution. It is TNPP free and contains an optimized level of stabilizers and does not contain any slip or anti-block additives.
TYPICAL APPLICATIONS
Bedding and Jacketing for low/medium voltage power cables and jacketing for telecommunication cables, electrical conduits and drip & irrigation pipes.
