What is the difference between polyurethane wheel and rubber wheel?

Rubber has always been the first choice of wheel manufacturing materials, because of its natural easy to obtain, low cost and widely favored by countries around the world. However, during World War II, materials such as rubber were in short supply. After people explore, finally found a more cost-effective material - polyurethane, rubber caster and polyurethane wheel what is the difference?

1. Hardness and elasticity of wheels

The hardness of the rubber wheel is generally 67-75 degrees, and the hardness is relatively low; The hardness of the polyurethane wheel is as high as 83-95 degrees. Under the premise of ensuring safety, polyurethane casters not only have large bearing capacity and small rolling resistance, but also ensure a certain cushioning capacity. What's more, the wheel hardness and elasticity of the polyurethane material can be adjusted according to the customer's requirements and the environment of use.

2. Castor raw materials

Rubber wheel: easy pollution, low production efficiency, raw materials can be mixed with recycled materials, odor;

Polyurethane caster: wheel surface requirements are high, the use of raw materials, no odor, can not be doped with recycled materials.

3. Ground marks

The rubber wheel is easy to leave carbon black marks on the ground during use; The basic chemical composition of polyurethane materials determines that polyurethane casters will not leave traces on the ground, even brightly colored wheels will not leave any traces of colorants on the ground.

Aging resistance: rubber casters contact organic solvents for a long time, easy to expand, tear strength and collapse resistance will be weakened; Even if the polyurethane caster is exposed to organic solvents for a long time, its performance is unchanged and will not be corroded. Wheel load: heavy rubber caster load of about 160-230kg, crack resistance and tear resistance is poor; The bearing capacity of polyurethane casters is about twice that of rubber wheels, and it has excellent anti-crack growth, anti-tear and anti-collapse properties. Even if placed for 7-8 years, the performance is still good, good wear resistance. Compared with rubber wheels, polyurethane casters such as plastic core polyurethane casters and iron core polyurethane casters have significantly higher bearing capacity, wear resistance, tear resistance, cutting resistance, rolling resistance and so on, and are favored by consumers, gradually replacing the original position of rubber wheels.
