What is rubber what are its applications?
There are two types of rubber in the world: synthetic rubber and natural rubber. The former is manufactured in a process requiring polymerisation, while the latter is made from an emulsion of the sap (latex) collected from rubber trees. An interesting fact: the name of this product comes from the verb “to rub”. EKI processes these types from a rubber roll, manufacturing strips, rings, blocks, frames and other shapes. These might include non-adhesive of self-adhesive custom rubber strips, support blocks, adjustment blocks, spacing blocks and rubber gaskets. These products can all be delivered with or without self-adhesive surface(s). Bearing pad rubber is a special type that is used in heavy bearing applications that require a good distribution of pressure, for example steel constructions beneath concrete floors or under glass plates. This material comes in different hardnesses, with the most common being 60 Shore A, 65 Shore A or 70 Shore A.
Rubber is made from different types of materials. At EKI, we process the following types: SBR, EPDM, neoprene, NBR, silicone and butyl.
SBR is the most commonly used raw material. SBR is mainly used for indoor applications; you won’t often see it used outdoors because it is less resistant to heat and weathering. When used indoors, it is very hard-wearing.
EPDM rubber is mainly used outdoors. It is very resistant to UV radiation and ozone, making it ideal for use in road construction. EPDM is also highly elastic and therefore often used as a rubber seal.
Neoprene rubber combines a number of the desirable properties found in other rubbers, making it a high-quality, versatile material. Depending on the quality, it has a light resistance to oil, making it popular for use in shipping and offshore applications. It is also widely used in public facilities.
NBR is even more resistant to oil than neoprene and is therefore commonly used in indoor applications where it comes into prolonged contact with oil. It also has good mechanical properties and has some resistance to UV and ozone. A well-known use for NBR is in the manufacture of O-rings.
Silicone rubber is ideal for use at high temperatures of up to 230-300°C. It is frequently used for applications involving contact with food, but also in clothing, accessories and DIY products. We deliver silicone in the colours white, black, red and transparent.
Butyl rubber has excellent resistance to UV radiation and ozone and is suitable for creating airtight seals, so it is often used outdoors. It is very easy to glue and is therefore often used as a rubber seal. One familiar application of the material is for bicycle inner tubes. Interestingly, it is also a raw material used in manufacturing chewing gum.
