CELLULAR RUBBER: THE COMPLEMENTARY RANGE TO ELASTOMERS

The range of cellular rubbers and expanded plastics (also more commonly known as ’foams’) was, historically, the second range of products developed by GRANDO in the 1960s and 70s in response to a growing demand from the market for these new flexible technical materials as well as technological advances in manufacturing methods.

In several areas of application, such as sealing and shock absorption, cellular rubbers and expanded plastics have become complementary to elastomers. This complementarity has allowed the areas of application of these two ranges of materials to be expanded.

As a rubber product manufacturer, cellular rubbers and expanded plastics represent a sizeable part of GRANDO‘s commercial activity, our materials science engineers continue to develop flexible products with ever greater mechanical, thermal and physico-chemical performances. These are intended not only for traditional industrial applications, but also for advanced technology sectors such as the rail, aeronautical, medical and food industries.

Thanks to our partnerships with several industrial and university laboratories, our cellular rubbers are accredited under several international standards, such as :

  • Fire/smoke standards for railways and buildings (EN-45-545, NF F-16-101, DIN 5510, UL94, NBN EN 13501-2, etc.).
  • FAR, NFL, ASTM, BOMBARDIER SMP800 standards for the aeronautical and space industries.
  • Food standards (e.g. FDA: Food and Drug Administration).
  • Standards for drinking water (e.g. ACS), etc.
