7 * 4 inch polyurethane foam wheel VPU0702
Resistant to sunlight, oxygen, ozone, and several other environmental factors. Damage caused by chemical resistant abrasives. Resistant to cutting and tearing, very durable. Under the same conditions as other materials, polyurethane has a slower wear rate, making it more durable. It has higher tensile strength, can withstand heavier loads, and has excellent elastic memory.
PU wheels are commonly known as Uni glue, spring glue, or polyurethane wheels.
PU wheel is an elastic body that lies between plastic and rubber, and its excellent and unique comprehensive performance is not possessed by ordinary plastic and rubber.
The elastomer of PU wheels has excellent properties such as wear resistance, chemical corrosion resistance, low pressure resistance, tear resistance, radiation resistance, high load-bearing, and shock absorption and buffering.
PU wheels have excellent sound absorption characteristics, and they do not produce noise during movement, achieving a silent effect.
PU wheels also have a wide hardness scale, ranging from Shore A10-100.
In addition, PU wheels have excellent shock-absorbing performance, can absorb shock and cushion the pad, and are more resistant to impact than metal springs, without damaging the mold. These characteristics of PU wheels are very suitable as castor materials.
The suitable environments for polyurethane (PU) wheels are:
1. Suitable for use on various surfaces.
2. Widely used in the medical industry, food processing industry, factory handling, warehousing logistics, machinery manufacturing, etc.
3. The temperature range for use is -35-80 ℃.
