Which polyurethane can be made wheels?
Polyurethanes are one of the most versatile plastic materials. The nature of the chemistry allows polyurethanes to be adapted to solve challenging problems, to be molded into unusual shapes and to enhance industrial and consumer products by adding comfort, warmth and convenience to our lives.
Polyurethanes are formed by reacting a polyol (an alcohol with more than two reactive hydroxyl groups per molecule) with a diisocyanate or a polymeric isocyanate in the presence of suitable catalysts and additives. Because a variety of diisocyanates and a wide range of polyols can be used to produce polyurethane, a broad spectrum of materials can be produced to meet the needs of specific applications.
It does not matter where you look, you are likely to find polyurethanes. Polyurethanes can be a found in mattresses, couches, insulation, liquid coatings and paints, tough elastomers such as roller blade wheels, soft flexible foam toys, some elastic fibers, and many other places and applications.
Polyurethane which makes wheels include component A and component B.We only use top-class polyurethane as raw materials of wheels, so our PU wheels is different with other manufacturers. We invested huge money to research and test polyurethane from different company to produce excellent wheels.
How are people made of PU wheel?
Raw materials of PU wheel include component A ,component B and accessory materials. I confirm that characteristic of polyurethane wheel depend on mainly accessory materials. Special PU foam tires must use special formula. We have developed five series of special use for PU wheel.

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.
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.
Consumer can use the PU wheel under cold weather.
Raw materials of the polyurethane tire don’t contain any harmful component to keep air clean.
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 inChinais 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.
