Neoprene or silicone rubber sheeting

When it comes to understanding whether you need silicone sheets or neoprene sheets, you need to compare the properties of both. In this article, rubber sheeting experts Martin's Rubber explain the difference between each material and help you decipher what rubber would best suit your application.

Silicone sheet or Neoprene sheet?

We'll start with silicone. Silicone is a semi-organic synthetic material that is designed to resist extreme temperatures up to 300°C and as low as -55°C. Silicone is an excellent electrical insulator, exhibits fire resistant characteristics and thermal stability; it is a soft, compressible material and is popular for a range of sealing applications. Silicone sponge sheet is, however, highly inert and does not react well with chemicals, particularly oils. Although silicone is the perfect material for heat resistance, it is not suitable for dynamic applications due to its poor tear strength.

Neoprene has been proving its performance for 75 years. It is effective for providing resistance to gasoline, sunlight, ozone and oxidation and has very good air- and water-tight sealing properties. This versatile rubber is the world's first ever synthetic oil resistant elastomer. Neoprene sponge rubber sheet is commonly used in marine environments, as well as construction and electronics industries, for weather strips, closure seals and shock/noise absorption.

Neoprene or silicone rubber sheeting - what are the differences?

The main distinguishing difference between neoprene and silicone sponge sheeting is that silicone is designed to withstand extreme temperatures but is not suitable to be used around oil. Whereas, Neoprene specialises in resisting moisture but is less suitable for high temperatures. Both materials have their obvious strengths and weaknesses, which is why they would always recommend speaking to one of their expert advisers here at Martin's Rubber to ensure that you select the right material for your application. They can help you understand if neoprene or silicone rubber sheeting would be best, precisely for your industry requirements.
