Why is notable different price of PU wheel among suppliers?


There are thousands of suppliers of polyurethane wheel in the world. Some companies quote very low price for customers, and another some give high price. In this case, importers often are confused. How do I choose PU foam wheel? Should I decide to buy cheap wheel or expensive one?  

Everyone knows that price bases on quality of products. Nobody will lose money for business. You will make wrong if you only pay attention to price of wheels. Now I discover the secret of price for you. These suppliers with low quotation have to add some calcium powder to raw materials of polyurethane wheel. Do you know price of calcium powder is very cheap? Do you know the component of raw materials of PU wheel is very expensive? I would like to confirm the price of raw materials of PU wheels get to USD4600/ton, and the price of calcium powder is only USD300/ton. Now you should understand why the price of PU foam wheel is so different.

These wheels that mix calcium powder to raw materials are easy to crack under normal condition, and their life is very short. Would you like to import these with low price?



Why do someone quote low price for PU foam wheels?


You can get 100 different price of polyurethane wheels if you inquiry 100 suppliers. Someone can quote very low price, and someone quote high price. Importers will be confused. How should I choose?

You must understand the point which raw materials of PU wheel is expensive. Some companies add calcium powder to raw materials to cut down production cost. They add weight of calcium powder according to quotation. In fact, buyer give any price, polyurethane wheel manufacturer can supply, but PU foam wheel quality is different.

Raw materials of PU wheels have A grade,B grade,C grade. Those very cheap PU wheel only use C grade and mix to calcium powder. Do you know calcium powder price is very cheap?

We produce only use A grade raw materials and special formula for high performance. Our company invested huge money for research of high performance PU wheel.



Do you know the standard of good PU wheel?


One of my customers said that rough surface is good. What do you think of the point? I think that most consumers don’t understand what is good for polyurethane wheel. As an expert of PU wheel, I would like to share some ideas.

Good PU foam wheel must bear features as followings:

1)      smooth surface without small holes.

2)      It can recover original shape under loading heavy weight.

3)      Don’t crack under cold weather.

4)      Long life under normal condition

If someone add some cheap materials to raw materials of PU wheel, they have no above characteristics. Do you dare to buy cheap PU foam wheel?



Do you know the best temperature for making PU wheels?


Polyurethane wheels which produce in Spring and Autumn are excellent PU wheel’s surface is smooth and pretty. It’s reasonable temperature’s range from 5 degree Celsius to 20 degree Celsius.


Why do PU wheels that produce in Summer and Winter is poor surface?

It contain more water in air in Summer, in same time, raw materials of polyurethane wheel also hold more water.

In very cold winter, foam temperature is too low, so foam effect is also poor.

I advise that customers place PU wheel order in Spring and Autumn.


If you have also other ideas, don’t hesitate to send me e-mail, then I require our technical team research and develop them to meet your personal requirement.


How to choose suitable PU wheels for your local market?


It is different for per consumer’s requirement. We are facing the times which time is money and safety is the first thing, which is a great era for someone who are seeking value of products. In this case, we developed several series of high performance for polyurethane wheels to meet customer’s will.

Customers fromAmericaand Europe need that performance of products is higher and higher. They pay more attention to excellent features than polyurethane wheel price.

In order to meet consumer’s requirement, we invested huge capitals to develop several series for PU wheels. All raw materials must be top grade. Our cost is two times as expensive as cheap raw materials price. Our technical team tested thousands of times for PU wheel with outstanding performance. At last, we succeed in high characteristics of polyurethane wheel industry.

I kindly ask for you to spend a little time to read following.

1)Wear proof type

Life of the PU wheel is very long, which is over one time longer than common one.

2)Loading heavy weight type  

The polyurethane wheels can load more quantity than normal wheels, so consumer can save some work   time. Consumer only uses the wheel under some special condition.

3)Anti-cracking type  

Consumer can use the PU wheel under cold weather.          

4)Eco-friendly type  

Raw materials of the polyurethane tire don’t contain any harmful component to keep air clean.    


5)Comfortable type

The polyurethane wheel can reduce fatigue when consumer uses it.  

Of course, these special PU foam wheel price is higher than common PU wheel price, but their value is very high. If you look for high value, I advise you use good PU wheels. If you like cheap PU foam wheel, you may choose common PU wheel.

PU wheel price fromChinais lower than developed countries, but our features is better than their polyurethane wheel. Why is this case? Cost of production in China is lower than developed countries.

We can produce common polyurethane wheels if you like low quality with low price. Most importers fromAmericaand Europe bought, are buying, will be buy outstanding characteristic PU wheels. Those importers from Middle East still like cheap PU wheels. Someone from Middle East also start import high quality PU foam wheels. As economic growing, more consumers in all the world like to use high quality PU wheels.

low-speed polyurethane foam wheels for children’s high-grade car



The utility model provides a polyurethane foam wheel of a low-speed high-grade car for children, so that the problems that an existing foam wheel is complex in structure and cumbersome in assembly in the prior art are solved. The polyurethane foam wheel of the low-speed high-grade car for children includes a wheel hub, electroplated protecting covers and wheel bodies which cover the outer circumferential surface of the wheel hub. The wheel hub comprises upper wheel hub bodies and lower wheel hub bodies, wherein the upper wheel hub bodies and the lower wheel hub bodies are detachably connected; the outer surfaces of the upper wheel hub bodies are fixedly connected with the electroplated protecting covers, and at least two reinforcing ribs are evenly distributed on the inner surface of each upper wheel hub body in the circumferential direction; the wheel hub is provided with a center hole used for accommodating an axle; the center hole is connected with the axle in a rotary mode through a matched wheel hub shaft. Due to the fact that the reinforcing ribs are arranged in the wheel hub, the service life of the wheel is prolonged, and loading capacity is large. The wheel hub shaft is arranged in the center of the wheel hub and comprises a clamping-buckling body, a clamping-bucking pressing piece and a shaft sleeve, and the clamping-buckling body and the clamping-bucking pressing piece are connected through a spring. Due to the pressing mode of the spring, the wheel hub shaft is more convenient to assemble and disassemble.


It is our goal that per customer who is different and high requirement is satisfied with our products and service.
