Specific tensile modulus GPa of various materials

Metals and glass generally support higher temperatures than polymers, which present a more or less plastic behaviour under stresses, leading to  

Polymers are sensitive to thermo-oxidation and, for some, to moisture degradation. Provided they are not subject to moisture degradation, polymers, unlike current steels, are not sensitive to corrosion. 

Polymers are sensitive to a greater or lesser degree to photo-degradation, which can limit their exterior uses. On the other hand, many polymers, including the commodities, are resistant to the chemicals usually met in industry or at home and displace the metals
