How is Rubber Made?

A short background of rubber. When most people refer to “rubber” they do not usually define what type of material it is. In common usage, rubber is typically used to refer to the PVC that is found in most plastic products. There are actually many other types of rubber, though they all fall into two general categories: natural rubber and synthetic rubber.

Natural rubber is primarily from trees. This type of rubber has been around for quite some time and is commonly used in everything from road construction to motor vehicle tyres. Synthetic rubber on the other hand, is a man-made version of a natural rubber. Most commonly used for manufacturing vehicle tyres, synthetic rubber contains the chemical ethylene, and is commonly used for high pressure purposes. Today, synthetic rubber is frequently mixed with natural rubber to produce an “antibacterial” variety of rubber which can be commonly found in most swimming pools.

How is rubber made? Rubber is crafted from a combination of three primary raw materials: sand, clay and oil. All three of these raw materials have distinct properties, though they are mixed together in order to create a wide range of qualities and thicknesses. For instance, sand and clay are extremely similar, yet they are mixed with oil in order to create the perfect blend of hardness, wear resistant characteristics and softness. Rubber is created from these mixtures during the process described above.
