Polyurethane (PU) is a relatively new material that combines the strength of plastics and the elasticity of rubber. Unlike rubber, it does not subject to weathering and does not participate in chemical reactions under normal conditions. It does not disintegrate easily and its life expectancy is very high. Polyurethane elastomers can withstand temperatures from artie-like cold conditions to 80°C-100°C depending on chosen material grade. Its superior properties make it a popular replacement for steel, plastic & other rubber materials.
