PP modulus examples GPa

Because of the versatility of polypropylene, its favoured application sectors are diverse  

The same basic propylene monomer induces many common properties and, unless otherwise specified, we will not make a distinction between the various subfamilies. Only the foams will be given special attention as they present particular properties due to their morphology  

The properties are close to those of polyethylenes, with some differences due to the tertiary carbon linked to the backbone good mechanical properties at ambient temperature, low price, attractive price/property ratios, easy processing, chemical inertness, we absorption of water, low density, good electrical insulation even in wet media, feasibility of welding, versatility of processing methods, broad range of available melt flow rates (MFR). 

Judiciously selected grades provide good impact and fatigue resistance, good stiffness and impact balance, suitability for food contact, low extractables,good organoleptic properties, the possibility of autoclave and radiation sterilization in the presence of aqueous solutions. .. 

The mineral, talc and, especially, fibreglass-filled grades are more rigid and have better behaviour and lower creep when the temperature rises.
