Rubber analysis and expertise of elastomers

The 6NAPSE Group carries out the analysis and characterization of elastomers and rubber. Our laboratory also offers a wide range of tests to check the conformity of elastomers.

Characteristics of elastomers and rubber

Elastomers are polymers with rubbery elasticity. Rubber is part of the elastomer family. It is an essential material in everyday life. Its exceptional mechanical properties (shock-absorbing, extensible, incompressible, rigid, adherent, etc.) make it a versatile material.

Elastomers are special polymers due to their capacity for elastic collisions, i.e. they return to their initial shapes after the stress stops. This advantage allows them to take different forms, particularly in the automotive industry. Its qualities are more exploited in tires, this sector consumes more than half of the production of elastomers, and the automotive industry: tires, seals, tubes, industrial supports, elastic connections, anti-vibration devices, etc.

This polymer is used in many other sectors such as the mechanical, aeronautical, electrical, transport, building, medicine and pharmacy industries, and even in the nuclear industry.
