LyondellBasell Australia's polypropylene grade HP401H is a low flow homopolymer with a conventional molecular weight distribution and is formulated with a general purpose additive package. HP401H is designed principally for the production of sheet for subsequent forming operations into packaging containers. The flow level has been chosen to provide a good balance between hot melt strength during processing and high production rates. Sheet and formed containers produced from HP401H exhibit an attractive balance of rigidity, clarity and impact performance.
