As shown below, polyurethane offers the engineer a remarkable range of properties and hardness's that enable them to outperform wood, metals, rubber or plastics in many applications . As you can see on the comparison chart on the next page, polyurethane offers a hardness range far wider than conventional rubbers
Oct 10, 2017 . In the case of PP and untreated wheat st fiber, however, severe thermal degradation prevented processing of the composite. The composites consisted of 80wt% PP and 20wt% fiber. We used injection molding to make standard samples of these composites to study their thermomechanical properties
