Wear and abrasion resistance caster wheels

Rubber is made from a mixture of different components, commonly known as a compound (or rubber compound). Rubber compounds usually have two primary components; "Raw rubber" and "filler", in addition to other ingredients in small quantities. Fillers are used to increase the tensile strength of materials as well as a range of other improvements in properties. Carbon black is the most common filler, and gives rubber caster wheels their black colour. Coloured rubber uses alternative fillers, such as silica. The rubber compound will usually be approx. 60-70% raw rubber and 30-40% filler. Carbon black particles and raw rubber atoms are bound by a chemical reaction that creates a mechanical bond between the two parts.

Polyurethane material is a synthetic material that is produced by the chemical reaction of various elements. While other additives can be mixed with polyurethane to enhance properties, the composition of the material provides an extremely high proportion of pure polyurethane in 95% of the area. While both materials have good levels of wear and abrasion resistance, and they have a service life of many years, polyurethane generally has a high level of resistance to abrasion and abrasion, and is 2-3 times higher under controlled tests. Life can happen. Rubber castor wheel.

The primary reason for this is due to the high concentration of pure polyurethane in polyurethane caster wheels Australia. On the other hand, a 60/40% mixture of rubber castor provides many molecular attachments that can be damaged under friction. With rubber casters, in the form of friction, stress is placed on the nuclear joints between raw rubber and carbon black, which in turn can lead to connection failure as a result of rubber wear.

Wear and abrasion resistance

Rubber is made from a mixture of different components, commonly known as a compound (or rubber compound). Rubber compounds usually have two primary components; "Raw rubber" and "filler", in addition to other ingredients in small quantities. Fillers are used to increase the tensile strength of materials as well as a range of other improvements in properties. Carbon black is the most common filler, and gives rubber casters their black colour. In addition, polyurethane casters have greatly improved the resistance to "splitting", "tearing" and "cutting" compared to rubber casters, allowing polyurethane wheels to be designed with a higher level of stress without the worry of physical damage.

This means that if two identical casters, with only a difference in material (i.e. rubber or polyurethane), the polyurethane wheel can be given a higher level of thrust and therefore allow it to be used at higher loads.
