EPDM Flexible Bellows, also known as EPR Flexible Bellows and ethylene propylene flexible Bellows, are designed as a cover or expansion bellows to take over axial, lateral and angular movements in pipeline systems and protect components against alkalis, strong alkaline, detergent, hot water, steam, ozone, etc.
EPDM Rubber Flexible Bellows and dust boots have wide sealing applications due to these excellent chemical resistance properties and its superior ozone resistance.
EPDM Flexible Bellows are usually produced by silicone rubber compression molding, extrusion moulding or rubber injection moulding.
