As of November 2006, the stiffest unreinforcedcommercially available material was 'Primospire' polyphenylene from Solvay Chemicals, with a flexural modulus of 1.2 Million PSI & tensile strength of 30,000 PSI.
Glass-filled materials may achieve higher stiffness, but at lower strength.

∙ 11y agoThe stiffness of a material is reported as its Young's Modulus.
Steel has a modulus in the vicinity of 200 GPa. (Giga Pascal)
Tungsten has a figure of 400 GPa. Beryllium has a modulus of 287 GPa.
Osmium comes in about 550 GPa.
And top of the list of course, but not a metal, is Diamond at 1220 GPa.

Plastic is the hardest material to recycle on earth because: 1: Plastic has to be separated into many different kinds by hand 2: If a mixture of plastic is not recycled together they either contaminate the melt or you get a lower grade of plastic than the originals. This is called "downcucling". 3: Plastics need more energy to recycle than any other materials
