The 51st Polyurethane Elastomer (Adhesive) Learning Class

Skateboards are usually mass-produced in an industrial environment. They are made from polyurethane, a versatile and durable synthetic material. Frank Nasworthy invented the polyurethane skateboard wheel in 1970. Polyurethane wheels have a rubber-like grip on the road surface, expanding the potential of skateboard usage. Different types of polyurethane skateboards differ mainly in hardness, diameter, color, and shape. A durometer is a measure of wheel hardness. Soft wheels best suited for cruising on hard surfaces have lower hardness, hard wheels that absorb little vibration have higher hardness, and diameters are the height of the wheels. Making polyurethane skateboards requires the use of special chemicals and machinery.

Polyurethane Skateboard Wheels

Mix a batch of polyurethane. The chemical composition of the polyurethane is mixed in an appropriate proportion in the measuring machine. Metering machines are machines that heat, mix, and distribute polyurethanes.

Add color. Add dyes or other types of pigments to the batch when the polyurethane in the meter is liquid. You only need to do this if you want the skateboard wheel to have color.

Pour the polyurethane into the mold. The mold should be made of aluminum and reflect the desired wheel shape and size.

After the polyurethane is cured, the polyurethane "lump" is removed from the mold. Ug is the basic raw form of a polyurethane skateboard wheel. Place the lumps on a flat surface to solidify completely.

Shape the wheels. Use a lathe to cut SL into certain shapes. The sides and driving surfaces of the wheels should be cut to exactly match each other. A lathe is a machine that rotates an object as it deforms. In this case, the lathe turns the plug as it cuts away excess polyurethane.

PU wheels for skate board


Mixed polyurethane does not necessarily need to be heated, although it can produce higher-quality wheels.


PU skateboard wheels supplier reminds that clear, colorless wheels are probably the strongest. Adding pigments or dyes to replace polyurethane may weaken the wheels.

The 51st Polyurethane Elastomer (Adhesive) Workshop will be held in Wenzhou, Zhejiang Province from November 20 to 22. We look forward to your joining. The China Polyurethane Industry Association Training Center is the earliest authoritative organization for training, organizes all kinds of polyurethane products and application technology, vocational skills. Training, exchanges, and seminars have been successfully held for more than 30 years. Urethane foam, polyurethane exterior wall insulation, polyurethane elastomer, polyurethane adhesive, training on topics such as testing and analysis of chemical agents, waterborne polyurethane, polyurethane raw materials and products, trained thousands of scientific research, production, and management personnel for domestic and foreign polyurethane enterprises and institutions. It is the best learning and communication platform in the domestic polyurethane industry, and it is the only official training platform, which is well-known in the industry.

Polyurethane elastomer, as a special synthetic rubber, has excellent wear resistance. It is said that it is easy to manufacture, the soft and hard formula is adjustable, the performance range is wide, and it is playing an important role. Application prospects are very broad, new applications and new technologies emerge endlessly. The raw product polyurethane elastic sealant is widely used in buildings, squares, and highways as caulking sealing materials, and automobile manufacturing, glass installation, electronic filing, and other industries.
