Elastomer Guide: Which Rubber Seal Is Suitable For Your Process?

Thermoplastic elastomers, sometimes referred to as TPEs or thermoplastic rubbers, are engineering standard polymers that offer superior viscoelasticity. Manufactured from co-polymers or a blend of rubber and a polymer, elastomers display excellent thermoplastic and elastomeric characteristics.

Elastomers offer significant benefits, not least their ability to moderately stretch yet return to their original shape afterwards. This helps durability under stress and longevity compared to other polymers, and can be adapted to many different purposes. Also, elastomers are more cost-effective, resist weathering and chemicals, and offer superlative colourability, without compromising on elasticity.

Choosing The Right Elastomer For Your Industrial Process

Selecting the right elastomer for your industrial process is essential, particularly if you need a material that will withstand specific conditions. Obtaining informed advice about your elastomer options is important, so speak to one of our experts to find out which TPE is right for your project.


Where will the elastomer be used and to which environmental conditions will it be exposed? No TPE offers a one-size-fits-all approach, so understanding how the elastomer will be used and the forces to which it will be subjected will ensure you choose the right product. When considering where the elastomer will be sited, think about the temperature of the working environment and exposure to water or chemicals. Choosing the wrong part could advance degradation, causing unnecessary replacement or repairs later, as well as affecting performance.


Every rubber compound is a blend of at least two elastomers. The formulation is a major influence on the function, lifespan, and cost of the final product. Understanding the ingredients will help to inform your choice. Carry out a test on a sample to determine the characteristics and suitability of the elastomer for the intended purpose. No elastomer offers all-round performance. For example, polyisoprene offers excellent tensile strength but poor resistance to UV, while fluorosilicone is resistant to ozone but not to abrasion.
