Acrylic doesn't have as much impact resistance as polycarbonate; polycarbonate's tensile strength is greater than that of PVC; PVC's heat deflection abilities are lesser than Vivak's; and so on, and so on.

Polyacronitrile 1.17 Specific Gravity (SG) is defined as the ratio of Also, it is relatively hard and resistant to impact and can be subjected to temperatures of up to 120 C without being affected. Specific Gravity "Density" has its own unit of measurement, 1 g/cm3 or 1 kg/m3, in contrast, specific gravity has no unit of measurement goes with it; nevertheless, although they don't have the same meaning, they have the same value because density of water is quite close to 1g/cm3. The specific gravity of plastic is the ratio of the density of plastic to that of a reference substance (Usually water). How about an incentive to share this post? This changes the ratio for our calculation; it is now 0.945/0.74 or 1.28. It is 250 times stronger and just as clear as glass.
