PU Wheels vs. Rubber Wheels
PU wheels are environmentally friendly tires. The main material of the tire is polyurethane. Strictly speaking, PU is also a kind of plastic. However, additives are added to the production process to make it superior in performance. It has puncture resistance, no expansion, high cost, good grip, not easy to slip, more wear resistance, and good comfort.
Solid rubber wheels are mainly used on flat roads in factory workshops and have the characteristics of low cost, puncture resistance, and corrosion resistance.
1. Polyurethane wheels
PU materials can be applied to shoe fabrics or load-bearing parts, such as high-end inline wheels, PU pulley for skateboard, PU pads, luggage wheels, shopping wheels, etc. In some sports and leisure products that young people love, such as drifting boards, vitality boards, skates, twisting cars, etc., the wheels are generally PU wheels. Why? Because these products need to bear personal weight, so I will take the drift board as an example. For a drift board that can withstand 100KG, the overall requirement is not only that the large board can withstand it, but also an important role player, that is, the wheel. Player friends, don't underestimate this wheel, it can be very useful. PU wheels have better elasticity. Wheels with better elasticity are more suitable for various technical actions, such as spinning, accelerating, retreating, leaping, etc.
2. Rubber solid wheel
The solid rubber wheels are made of rubber. Rubber is a highly elastic polymer material with reversible deformation. It has abundant elasticity at room temperature, can produce larger deformation under the action of small external force, and can return to the original state after removing the external force. Rubber is a completely amorphous polymer. Its glass transition temperature (T g) is low, and its molecular weight is often larger, greater than several hundred thousand.
The impact of rubber reinforcement performance is mainly the impact of tensile strength and tear strength. The general rule is: In the case of the same particle size, high-structure carbon black has a greater reinforcing effect on amorphous rubber, and generally has higher tensile strength, and tear strength. The structural performance of rubber is also the most important factor affecting its electrical conductivity. The chain structure easily forms a conductive path in the rubber and is entangled with each other, thereby improving the conductive performance of the rubber.
Isoprene rubber, like natural rubber, has good elasticity and abrasion resistance, excellent heat resistance, and good chemical stability. The strength of isoprene rubber raw meal (unprocessed) is significantly lower than natural rubber, but its quality uniformity and processing performance are better than natural rubber. Isoprene rubber can replace natural rubber to make truck tires and off-road tires. It can also be used to produce various rubber products.
