LLDPE
沙特基础 (SABIC)
产品描述
P438J is a medium density LLDPE natural resin and TNPP free designed for extrusion applications. This grade combines stiffness, toughness, high melt strength and low gel content coupled to excellent processability due to its tailored molecular weight distribution and flow properties. It contains an optimized level of stabilizers and is free from any slip or anti-block additives.
TYPICAL APPLICATIONS
Cylindrical and tape drip irrigation pipes. This grade is also suitable for other extrusion applications such as Medium and Low Voltage Cable Sheathing, electrical conduits and thin wall tubes.
