Perfluoroelastomer O-Rings
Perfluoroelastomer (FFKM) o-rings are recommended for their vast temperature range, chemical resistance in numerous aggressive applications, and long service life. Global O-Ring and Seal provides high-performance FFKM o-rings for your demanding applications. Our FFKM sealing solutions include Kalrez®, Chemraz®, and MARKEZ®.
Kalrez® O 形圈
Kalrez® 全氟弹性体 (FFKM) 零件可耐受 1,800 多种不同的化学品，同时具有高温稳定性。它们用于高腐蚀性化学加工、半导体晶圆制造、制药、石油和天然气回收以及航空航天应用。 Kalrez® 零件经过验证的长期性能意味着减少密封件更换、维修和检查的频率，增加工艺和设备的正常运行时间，从而提高生产率和产量。
Chemraz® O 形圈
Chemraz® 是适用于要求苛刻的油田应用的终极弹性体，当暴露于井下发现的腐蚀性化学品混合物时，可提供出色的密封性能，并且通常由操作员指定。我们配制了特殊化合物，以提高对快速气体减压和磨损的抵抗力，从而显着减少停机时间和维护。
MARKEZ® O-Rings
MARKEZ® is a high-performance perfluoroelastomer (FFKM) compound line built to address very demanding sealing environments. Formulated from ingredients similar to premium FFKM brands, MARKEZ® delivers excellent chemical resistance and high temperature performance, with heat resistance up to 635°F (335°C) depending on compound selected, at outstanding value.
