Difference between Skateboard Pu Wheel and Rubber Wheel
Mar. 09, 2020
PU wheels are environmentally friendly tires. The main material of the tires is polyurethane. Strictly speaking, PU is also a kind of plastic. However, additives are added during the production process, which results in superior performance. It has puncture resistance, no inflation, high cost, good grip, not easy to slip, more wear-resistant, and good comfort.
Rubber solid wheels are mainly used on the flat pavement of the factory workshop, which has the characteristics of low cost, puncture resistance and corrosion resistance.
1. PU round
PU material can be applied to the fabric of shoes or parts that bear weight, such as high-end inline wheels, pu pulley for skateboard, PU pads, luggage wheels, shopping wheels and other wheels. In some sports and leisure products favored by young people such as drift boards, vitality boards, skates, twist cars, etc., the wheels are generally PU wheels. WHY? Because these products need to bear individual weight, I will take the drift board as an example. For a drift board to withstand 100KG, the overall requirement is not only that the large board can withstand it, but also an important role player, which is the wheel. Player friends, don't underestimate this wheel, it can be very useful. PU wheels have significantly better elasticity. The wheels with better elasticity are more suitable for various technical movements, such as rotation, acceleration, retrograde, prancing.
2.Rubber solid wheel
Rubber solid wheels are made of rubber. Rubber refers to a highly elastic polymer material with reversible deformation. It is rich in elasticity at room temperature, can produce large deformation under a small external force, and can return to its original state after removing external force. Rubber is a completely amorphous polymer. Its glass transition temperature (T g) is low, and its molecular weight is often large, greater than several hundred thousand.
The effect of rubber reinforcement performance is mainly on tensile strength and tear strength. The general rule is: when the particle size is the same, high-structure carbon black has a large reinforcing effect on amorphous rubber, and generally has higher tensile strength. And tear strength. The structural property of rubber is also the most important factor that affects the conductive properties. The chain-like structure is apt to form conductive paths that are intertwined in the rubber, which will improve the conductive properties.
Isoprene rubber, like natural rubber, has good elasticity and abrasion resistance, excellent heat resistance and good chemical stability. Isoprene rubber raw rubber (unprocessed) has significantly lower strength than natural rubber, but has better quality uniformity and processing performance than natural rubber. Isoprene rubber can be used instead of natural rubber to make truck tires and off-road tires. It can also be used to produce various rubber products.
