With 50 years experience, 3P provides efficient and reliable piston rings to a whole range of applications, from shock absorbers to compressors. 3P’s pistons rings, bands or back-up rings are used in lubricated or dry-running conditions, where wear rate, friction and sealing are the most important performances. PTFE is well-known for its friction coefficient among the lowest ones. It allows also a wide temperature range (from -200°C to 260 °C) and long-life performance as it is chemically resistant and shows low ageing. To enhance performance, 3P offers high performance thermoplastics, like PEEK, and has developed a full range of compounds with PTFE or thermoplastic matrices. 3P offers: - Strong expertise in matching compounds to piston materials and fluids o Dedicated team to guide material choice o Testing facilities for tribology, sealing, wear, friction o Standard and original compounds to control leakage, lower friction or increase lifetime o Strong partnerships with worldwide material suppliers to test enhanced properties - Design capabilities to reduce material cost - Large range of processes and designs available: continuous ring, straight joints, scarf joints, overlapped joints, band bearings, thermoplastic injection moulding, overmoulded or thermoformed pistons - Product quality and production reliability, with proven track record at automotive OEM and Tier 1 supplier
