CEF polymers

Since 1961

CEF POLYMERES contributes to the reliability and optimisation of mechanical assemblies. We design and produce elastomeric solutions to deal with problems related to vibrations, shocks, contact wear, chemical constraints and sealing. Our high performance formulations combined with our expertise in the field since 1961 ensure that you get the results you expect and that you receive the best possible support in your developments.

The quality we bring to our products will help you to reduce your costs. Elastomeric parts are low value compared to other components but can cost you the most if they have a limited life or are poorly defined.

Polyurethane Moulding Solution

CEF Strathane polyurethane elastomers have very high physical and mechanical properties. We produce flexible or very rigid parts from 20 Sh A to 99 Sh A. The gravity casting process, identical to the foundry process, does not require large mould investments. Furthermore, the process allows a fast production start-up even for single parts.
Production at the Valence site
6 high precision casting machines

Rubber to Metal Moulding Solution Antivibration

Supports and shock absorbers, feet and wedges, plates and supports, air cushions several ranges of solutions to fight against vibrations and shocks
Production at the Turkey site
32 compression presses, compression transfer, injection

Tyre Solutions

Comprimatic diaphragm cylinders are used for actions where sensitive and precise adjustment is required.

OUR VALUES

  • Supporting our clients in their development.
  • Seek optimal quality with regard to cost objectives.
  • Durability of proposed solutions. We are able to replace the products we sold in the 1960s.
  • Encourage the promotion and creativity of our employees.
  • Maintain a winning partnership with our subcontractors.
  • Maintain a responsive organisation.
  • Use the least harmful and polluting chemicals.

EXPERTISE

A recognised know-how in the design and production of elastomer components for dynamic constraints. CEF Polymères is one of the few companies that can master the transformation of a range of elastomers that are complementary but very different in their process.

  • Polyurethane from 20 Sh A to 80 Sh D.
  • Rubber - metal NR NBR CR EPDM VMQ from 35 Sh A to 90 Sh A
  • 2 production sites dedicated to the polyurethane and rubber-metal moulding sectors
  • Production France and Low Cost.
  • Partnership and European Sourcing.
  • Integrated design office with trade-specific calculation tools.
