ELASTOMERS

An elastomer is a polymer with elastic properties, obtained after crosslinking. These properties are important because they allow the materials to withstand large deformations without degrading.

An elastomer known to all is rubber!

These materials are, from a chemical point of view, characterized by a low glass transition (below -40°C). Note that the glass transition of a polymer is an excellent indicator of its flexibility.

The so-called "raw" elastomers must undergo a transformation in order to be usable, the final product is therefore composed of 40% elastomers and 60% of various compounds: fillers, plasticizers, additives, etc.

You meet needs:

The most widespread use of elastomers is that of the automotive field for tires and shock absorbers in particular. But they are present in a large number of other fields such as: health, for rubber gloves, construction for cable sheaths, soundproofing, sealing, but also the food industry (conservation jar seals)

It sometimes happens that our customers are confronted with products which break quickly, and which do not show any resistance to deformations or that they are suspicious as to the composition of their products.

Polymex accompanies you:

Whatever your problem, Polymex can help you!

Do you want to check the composition of your elastomers and therefore carry out a deformulation? Our team can offer you a panel of analyzes to meet your needs:

  • Focus on the presence of adjuvants such as anti-UV, accelerator… thanks to structural analyzes or analysis of semi-volatile compounds.
  • Thermal analyzes to determine the content of polymeric fraction and residual charge and observation of the thermal phenomena observed.
  • Verification of the glass transition temperature (Tg) by DSC (Differential Scanning Calorimetry).
  • Identification of mineral fillers and elements present by ICP and SEM/EDX.
The laboratory will offer you tailor-made support in order to best respond to your problem.
