How to recognize the caster material? From the burning characteristics and wear coefficient of two aspects of details

When purchasing casters, we need to pay attention to the material of the casters, because the material of the casters is directly related to the comfort, durability and safety of use. In this article, we will introduce how to identify the caster material from the two aspects of caster burning characteristics and wear resistance coefficient.

Burning Characteristics

Casters made of different materials exhibit different characteristics when burned, which is an important aspect we can use to identify the material. Specifically:
Nylon (PA): not easy to burn, burning yellow flame, with nail odor, burnt wool smell, and produce white smoke, burning surface blistering, molten droplets.
Polyurethane (PU): easy to burn, burning with a faint white smoke, easy to melt, no irritating odor, sticky silk.
Polyvinyl chloride (PVC): easy to burn, burning with thick black smoke, irritating odor, burning without sticky silk, the surface after burning black carbon powder.
Polypropylene (PP): easy to burn, there is a faint plastic odor, burning surface uniform melting, and sticky silk. Nylon (PA): not easy to burn, burning with the odor of burning hair, after burning the surface has a blistering, and sticky silk.

Abrasion resistance

The wear resistance of casters is also an important factor affecting the service life, and the wear resistance coefficient of casters made of different materials is also different. Specifically:
Nylon wheel: nylon wheel wear resistance is also better, suitable for use on the level road surface, but relative to the rubber wheel is slightly inferior.
Rubber wheel: rubber wheel has good abrasion resistance, can adapt to a variety of road surfaces, longer service life.
PVC wheel: PVC wheel has poor abrasion resistance, easy to be worn and scratched, shorter service life.
Soft rubber wheel: soft rubber wheel has better abrasion resistance, but it is slightly inferior compared with rubber wheel.
Therefore, we can judge the material by observing the wear and tear of the casters in the process of use and understanding the wear resistance coefficients of various materials.

It should be noted that the above are only two aspects of caster material. In fact, there are other aspects of caster material, such as weight and strength, which will also affect the performance of casters. Therefore, when buying equipment, we need to comprehensively consider a number of factors and choose the most suitable material for ourselves.
