We are a skateboard PU wheel supplier, let us introduce you the difference between a PU wheel and a rubber solid wheel.

The PU wheel is an environmentally friendly tire. The main material of the tire is polyurethane. Strictly speaking, PU is also a kind of plastic. It only adds additives in the production process, which leads to superior performance. It has the characteristics of puncture resistance, no need to inflate, high cost, good grip, not easy to slip, more wear resistance and good comfort performance.

The rubber solid wheel is mainly used in the smooth pavement of the factory floor, and has the characteristics of low cost, puncture resistance and corrosion resistance.

1. PU wheel. The PU material can be applied to the fabric of the footwear or the part bearing the weight, such as high-grade in-line wheel, skateboard wheel, PU pad, box wheel, shopping push wheel and other purpose wheels, in sports products such as drift board, vitality board In some sports and leisure products favored by young friends, such as skates, twisting cars, etc., the wheels are generally PU wheels. WHY? Because these products are subject to personal weight, I will use the drift board as an example. A drift board needs to withstand a force of 100KG. The overall requirement is not only that the board can withstand it, but also an important role-player, which is the wheel. Players and friends should not underestimate this wheel, its role can be great. The PU wheel has a significantly better elasticity, and the better the elasticity, PU wheels for skate board is more suitable for a variety of technical actions, such as rotation, acceleration, retrograde, prancing and so on.

2. Rubber solid wheel. The rubber solid wheel is made of rubber. Rubber refers to a highly elastic polymer material with reversible deformation. It is elastic at room temperature and can be deformed under a small external force. It can be restored to its original state after removing external force. Rubber is a completely amorphous polymer with a low glass transition temperature (T g) and a large molecular weight of more than several hundred thousand.

The effect of rubber reinforcing performance is mainly on tensile strength and tear strength. The general rule is: when the particle size is the same, the high-structure carbon black has a strong reinforcing effect on the non-crystalline rubber, and generally has a high tensile strength. And tear strength. Rubber structure is also the most important factor affecting the electrical conductivity. The chain structure is easy to form an interwoven conductive path in the rubber, which will improve the conductivity.

Like natural rubber, isoprene rubber has good elasticity and wear resistance, excellent heat resistance and good chemical stability. The strength of the isoprene rubber (unprocessed) is significantly lower than that of natural rubber, but the quality uniformity and processing properties are superior to those of natural rubber. Isoprene rubber can be used to make heavy duty tires and off-road tires instead of natural rubber. It can also be used to produce a variety of rubber products.
