Sasol Polymers PP CHR440

About
Features Low flow Recommended for applications where superior impact properties and toughness are required at ambient temperatures as well as below 0°C. Contains a nucleating agent which ensures rapid crystallisation, resulting in an improved impact to stiffness balance as well as shorter cooling times Applications Injection moulding Industrial crates and boxes Transport containers Automotive components Extrusion Twin walled corrugated sheeting Monolayer or composite thermoforming films Pipe and profile extrusion Blow moulding Blow moulding of containers up to 1 litre in capacity&&
