Polymer young modulus
WebSep 8, 2024 · Polypropylene (PP) Copolymer. PP copolymer is a thermoplastic, further classified as a polypropylene plastic. It has a fairly low density and can have a moderately low tensile strength among thermoplastics. The properties of PP copolymer include three common variations. This page shows summary ranges across all of them. WebMar 1, 2024 · It can be observed that with increasing temperature, the strength of the material decreases for all the polymers. Young’s modulus for PTFE at 120 °C is 0.276 GPa, which becomes 0.05 at 250 °C. Whereas, Young’s modulus is found as 2 and 0.1 GPa at 140 and 250 °C, respectively for PEEK and 1.89 and 0.4 GPa at 165 and 275 °C for PEKK.
