Advantages and Disadvantages of Rubber and PU

Advantages and disadvantages of rubber:

Advantages: Rubber has good elasticity, insulation properties, and is impermeable to water and air. It is a highly elastic polymer compound that is widely used in various aspects of industry and daily life. The characteristics of rubber also include good wear resistance, high elasticity, and tensile strength, among others.

Disadvantages: Rubber has the shortcomings of a short lifespan, poor wear resistance, and low tear strength during use. Especially in applications such as truck tires, their limited load capacity often leads to tire blowouts. In addition, rubber tends to soften at high temperatures. After being used for a long time and oxidizing, will become sticky and melt.

Advantages and Disadvantages of Polyurethane:

Advantages: Polyurethane has excellent wear resistance, corrosion resistance, and impact resistance. It also has good oil resistance, toughness, wear resistance, aging resistance, and adhesion properties. The friction coefficient of polyurethane is relatively high, generally above 0.5.

Disadvantages: Polyurethane is not resistant to hydrolysis at high temperatures, nor is it resistant to alkaline media. The disadvantages of polyurethane also include a low friction coefficient and poor resistance to aging. Polyurethane will turn yellow after prolonged use.
