HDPE/HDPE-g-MA (95/5) and HDPE/HDPE-g-MA/clay with [alpha] values of 1 to 4 were melt compounded using a twin screw extruder, and then processed via three different routes: compression moulding, compression moulding followed by biaxial stretching or blown film extrusion.
The nanocomposite pellets produced above were then processed via the following routes: compression moulding, compression moulding followed by biaxial stretching and blown film extrusion.
The breakthrough process, which combines compression moulding and blow moulding, delivers significant advantages over conventional processes, providing enhanced quality, higher productivity, sustainability benefits, and the potential for lightweighting.
Covers product design and development, including: materials selection, processing techniques, film blowing thermoforming, blow moulding, rotational moulding compression moulding and injection moulding.
