SABIC® HDPE GF1442
HDPE
沙特基础 (SABIC)
产品描述
SABIC® GF1442 is a High Density Polyethylene resin grade specially designed for extrusion applications. This grade combines stiffness, toughness, high melt strength and coupled to excellent processability due to its tailored molecular properties design and flow properties. It contains an optimized level of stabilizers and is free from any slip or anti-block additives.
TYPICAL APPLICATIONS
SABIC® GF1442 is typically used in extrusion of Geomembrane applications with superior tensile properties.
Blown Film applications due to excellent processability, flow properties and mechanical properties.
