Properties of Fuel Resistant Rubber Sheets in Industrial Applications

 

fuel resistant rubber sheets

As with any foam solution, there are advantages and disadvantages of polyethylene foam. We have listed some of the most common ones in this article. Over time, these substitutes have become more advantageous over their natural predecessor, especially where contact with fuel and oil is present.

Most prevalent in the automotive and aeronautical industries, fuel resistant rubber has proven to be indispensable due to its effective resistance to abrasion, heat, water and gas. There are many types of rubber sheeting available, and choosing the right one that offers the perfect properties for its intended application is dependent on a handful of factors, such as working temperature and chemical resistance.

Uses of Fuel Resistant Rubber Sheeting

As previously mentioned, fuel resistant sheet rubber is used most commonly in the automotive and aeronautical industries, where contact with fuel, oil, and heat is an everyday occurrence. Accordingly, a rubber that keeps its mechanical properties when exposed to these conditions is required.  Fuel resistant rubber is often used for:

  • Hoses
  • Seals
  • Grommets
  • Self-sealing fuel tanks

As you can see, fuel resistant elastomers are hard to come by, with Nitrile (also known as NBR) being the top contender of the rubber sheet we supply here at Alanto.

Nitrile as a Fuel Resistant Rubber

When looking in more detail, it’s easy to see why Nitrile is one of the most commonly used elastomers in the world. Not only does it have high resistance to petroleum, fuels, oils and most solvents, it is also effective in resisting against heat, abrasion, and gas. Although, the rubber does have its downsides. The main disadvantage of using Nitrile rubber sheeting is that it is susceptible to oxidative ageing and ozone attack, eventually causing cracks and degradation over time. Another disadvantage of Nitrile is that it has low pliability - the more nitrile there is in the polymer, the higher the resistance to oils and fuels but the lower the flexibility.

The Environmental Impact on Rubber Sheeting

Environmental issues are rapidly forcing us to change the way we live, for example, the growing need to decrease dependence on fossil fuels which has lead to the introduction of biofuels. Investigations are already being carried out into the effects of biodiesels on polymeric materials such as Nitrile, as characteristics are present that increase its corrosive and degradation effects on elastomers. Studies have already found that swelling, cracking and deformation can occur with higher concentrations of biodiesel, as well as a decrease in tensile strength.

Of course, there are more factors to consider when choosing exactly which rubber you need, so if you’re still unsure of the most suitable material for your project, simply get in touch and one of our experts will be on hand to answer any queries you may have.
