PP is practically unbreakable and will not crack under pressure. PP in addition has a hardness which comes close to PS, with an impact resistance similar to PE. The material also looks like PE, but is slightly harder and stiffer than HDPE. PP can be strengthened by adding glass fibres.
PP is also available as hard structural foam.
