1 overview STRATEGIC POLYMER SOLUTIONS CEF Polymères S.A.S

2 FOCUS POLYURETHANE SOLUTIONS CEF develops, manufactures and sells polymeric technical parts and integrated systems made out of rubber and polyurethane. ANTI-VIBRATION SOLUTIONS We offer a range of high added-value products designed to cope with dynamic stresses, enhance safety, cushion against shocks, insulate vibrations, reduce abrasive wear and noise. Components for sealing, Attaching Spring elements. Levelling supports. OUR COMMITMENTS To provide support to our customers throughout their project development PNEUMATIC SOLUTIONS DIAPHRAGM CYLINDERS ˮ SINCE 1961 To ensure optimal quality while meeting cost objectives Ensure the durability of the solutions we offer. We are capable of replacing products we sold in the 1960s To help our workforce to develop and be creative To maintain a win-win partnership with subcontractors To maintain a reactive organization To use the safest and most environmentally-friendly chemicals
