Performance advantages of plastics

Plastics have a number of performance advantages over other materials, due to their light weight, durability, flexibility, wear resistance and slip resistance. Below are some helpful graphs that show comparisons of key performance advantages of plastics, including:

  • Compressive Strength
  • Tensile Strength
  • Coefficient of Friction
  • Moisture Absorption
  • Maximum Operating Temperature
  • Impact Strength
