RUBBER POLYMERS FOR CASTER WHEELS

Rubber can be used for various applications, including Rubber Castor Wheels.  Broadly speaking, Rubber can be put into two categories:

Rubber Caster Wheels - Trolley Wheels
Rubber Caster Wheels Ideal for Heavy Duty Trolley Wheels
  • Natural Rubber made from the Latex of the Hevea Brasiliensis Tree
  • Synthetic Man Made Rubber created from chemicals produced from petroleum refining.

Considering there are many different rubber types available, a lot of which appear

to look identical, but with differing properties, the selection of the correct rubber type for your Castor Wheel can be critical.

In this Blog we will look at Natural Rubber (NR) and Styrenebutadiene (SBR) for use in Industrial Wheels.

Black Rubber Caster Wheels – Perfect for Industrial Equipment

The standard Black Rubber Castor is normally produced from a mixture of NR and

SBR, with formulations comparable to automotive wheels.

In order to provide the required properties of the rubber castor, for example Tensile Strength, Wear Resistance and Flexibility, the mixture must be blended with fillers, chemicals and additives. This mixture is named a “compound”.

The principal ingredients of a Rubber mixture included around 50-60% raw rubber, Carbon Black Particles, and various chemicals to provide resistance to Ozone and Sunlight. In addition to assist the materials processing and manufacturing method oil may be used to help process the material, and also Sulphur which is employed to vulcanise the rubber mixture,

After the substances have been produced it is ready to be utilized for the moulding process.

For most Casters the tires are made by Compression moulding method, that is a relatively simple technique whereby a Mould Tool is created to the required profile of the caster wheel. The compound is placed into mould, together with the wheel hub which includes being covered with an adhesive. The mould is usually closed and held under great pressure by a heated press enabling the rubber to amalgamate and form into the shape of the tyre. The Mould is then simply opened and the completed product is removed.

The advantages of Black Rubber Casters:

  • Provide Low Noise properties
  • Protect flooring from damage
  • Perfect for Rough Ground
  • Excellent Grip
  • Low Cost
