Technical reinforcement textiles recommended by EFFBE

EFFBE’s expertise lies in the choice of the fabric best suited to controlling the adhesion between the rubber and the fibres. EFFBE’s technicians have an extensive database of accessible materials and a wealth of experience at their disposal, enabling them to propose the best concepts for diaphragm performance and service life.

Polyester, cellulose, aramid, polyamide... find out more about the reinforcing textiles used by EFFBE to manufacture its diaphragms

EFFBE has selected knitted, warp and weft fabrics as mechanical reinforcements for the manufacture of its diaphragms. These textiles provide both resistance to pressure (burst strength) and anti-tear safety.

The parameters for recommending the technical textile to be used are the stroke and shape of the diaphragm and the elastomer chosen, as well as the extreme working temperatures and the chemical environments to which the future diaphragm will be exposed.


Polyesters represent a balanced choice between performance and cost. Polyester fabrics are light, flexible and strong.


Polyamide fabrics offer very high resistance, enabling the production of strong diaphragms that respond perfectly to very high pressures and temperature ranges.


Aramids are fabrics with extremely high thermal stability. They are generally used when diaphragms are operated in extreme conditions. These fabrics are also the most suitable for surface modification to improve adhesion with the various rubbers.


Cellulosic fabrics are materials historically known for their flexibility and longevity, which are partly responsible for EFFBE’s historic success. However, their use is restricted by their limited resistance to extreme conditions.
