The flexural modulus of PLA is higher than polystyrene and PLA has good heat sealability. Although PLA performs mechanically similar to PET for properties of tensile strength and elastic modulus , the material is very brittle and results in less than 10% elongation at break. [ 21 ]
— "Values ranging from 21.3 to 21.5 gm/cm 3 at 20 °C have been reported for the density of annealed platinum; the best value being about 21.45 gm/cm 3 at 20 °C." 21.46 g/cm 3 — Rose, T. Kirke. The Precious Metals, Comprising Gold, Silver and Platinum .
The gram per cubic centimetre is a unit of density in the CGS system, and is commonly used in chemistry. It is defined by dividing the CGS unit of mass, the gram, by the CGS unit of volume, the cubic centimetre. The official SI symbols are g/cm 3, g·cm −3, or g cm −3. It is equivalent to the units gram per millilitre (g/mL) and kilogram ...
The plastic nurdles are always white or clear. Pigments or other additives are added to the material before it is melted to create coloured filament or filament with special properties, e.g. increased strength or magnetic properties. Before the filament is extruded the nurdles are heated to 80 °C to dry it and reduce water content.
Its amorphous density at 25 °C is 1.27 g/cm 3 (.046 lb/in³). It is prone to stress cracking in chlorinated solvents . Polyetherimide is able to resist high temperatures while maintaining stable electrical properties over a wide range of frequencies.

One Yuri equals 1 Pa⋅m 3 /kg or 1 N⋅m/kg, which is the breaking/yielding force per linear density of the cable under tension. [ 42 ] [ 43 ] A functional Earth space elevator would require a tether of 30–80 megaYuri (corresponding to 3100–8200 km of breaking length).
They have yield strengths as high as 2.4 GPa (350,000 psi) and density as low as 0.97 g/mL (0.035 lb/cu in) (for Dyneema SK75). [12] High-strength steels have comparable yield strengths, and low-carbon steels have yield strengths much lower (around 0.5 GPa (73,000 psi)).
