The Difference Between PU Wheel And Rubber Wheel

The Difference Between PU Wheel And Rubber Wheel
1. PU wheel
Pu material can be applied to the textile of shoes or the parts birthing the weight, such as top-quality straight row wheel, PU wheel for skateboard wheel, Pu pad, case wheel, shopping cartwheel, and also other function wheels. In the sports items, such as drift board, vigor board, skate, twist vehicle, and also other sports and leisure products favored by young adults, the wheels are usually Pu wheels. Why? Since these items need to bear individual weight, let me take the drift board as an instance. If a drift board wants to birth a pressure of 100kg, its total demand is not just that the big board can bear, but added that an essential role player is a wheel. Do not undervalue this wheel, players as well as buddies. It's really useful. Pu wheels are dramatically extra flexible, as well as the more versatile the wheels are, the better they are for all sort of technical activities, such as rotation, acceleration, retrograde, jumping, etc.
2. Rubber wheel
Rubber wheels are constructed from rubber. Rubber is a sort of high flexible polymer material with relatively easy-to-fix contortion. It is elastic at area temperature and also can produce large deformation under a small exterior force. After eliminating the external pressure, it can go back to its original state. Rubber is a completely amorphous polymer. Its glass change temperature (TG) is low, as well as its molecular weight is often huge, greater than several hundred thousand.
The basic regulation is that when the bit dimension is the same, the carbon black with high structure has a big reinforcing result on the amorphous rubber, and also usually has high tensile toughness and tear stamina. Rubber structure is additionally one of the most essential variables to influence conductivity. The chain branch structure is easy to form an interlaced conductive course in rubber, which will enhance the conductivity.
Isoprene rubber, like natural rubber, has excellent flexibility, put-on resistance, warm resistance, and chemical stability. The strength of raw isoprene rubber (prior to processing) is considerably less than that of natural rubber, yet its quality uniformity and processability are better than that of natural rubber. Isoprene rubber can change natural rubber to make vehicle tires as well as off-road tires, and also can additionally be used to generate various rubber products.
