HIGH PERFORMANCE FIBER GASKET

The Best of Both Worlds Meeting the challenge: sealing between flat surfaces In a variety of industries and critical applications, flat gaskets provide a static seal between two flat sealing surfaces. In flanges they connect valves, fittings, pipes, and pumps, where they are often subjected to aggressive media. To be effective, gaskets must be able to form a tight seal and have the strength to withstand challenging operating environments. When flat surfaces in components join, unevenness and roughness are unavoidable. Typically, wide spacing of bolts can cause flanges to bend or deform, resulting...

Combining tight fit and robust strength Flat seals from Trelleborg Sealing Solutions in HMF17 resolve these issues by bridging the gap between traditional fiber gaskets and rubber gaskets. This completely new material composition combines the flexibility and tight fit of an elastomer with the robust strength and mechanical stability of a fiber material. The material’s innovative mix of high-quality aramid fibers, special functional fillers, and Nitrile Butadiene Rubber (NBR) provides a unique performance profile. The material's flexibility, almost like that of an elastomer, simplifies the fitting...

Combining the key properties of elastomer and traditional fiber gaskets, the innovative FlatSeal™ HMF17 is the optimum choice when tight sealing and mechanical strength are required. • Excellent adaptability to unevenness at minimum surface pressure levels and during installation • Extremely low leakage levels even when surface pressure is • Mechanical stability • Stable long-term properties at moderate operating temperatures • Good resistance to media and aging • Smooth processability and safe handling even with complex gasket outlines • Full traceability of gaskets with FlatSeal™ Code Technology...

Proven Performance Because of its unique raw material concept and advanced processing technology that results in enhanced material flexibility, the FlatSealTM HMF17 offers reliable sealing, even with minimal or inconsistent surface pressure. Numerous tests have been performed to prove the performance of FlatSealTM HMF 17. BREAKTHROUGH IN LEAK-TIGHTNESS At an internal pressure level of 10 bar / 145 psi, in relation to the surface pressure level, FlatSeal™ HMF17 is significantly better at preventing leakage than conventional fiber gaskets. Comparison of leakage performance - HMF17 with standard...

PIONEERING INNOVATIONS TEMPERATURE TESTS DEMONSTRATE SUPERIOR RESULTS Testing of FlatSeal™ HMF17 focused on determining how the gasket deforms when application temperatures increase. Temperature testing consists of two parts: • First, the gasket is compressed at room temperature between two surfaces. The curve in the graph indicates the adaptability of the gasket during installation. • In the second part of the test, the temperature is increased at a specified speed, while the surface pressure from the first step is held constant - the system is not allowed to “relax” as a result of gasket compression....

FlatSeal™ HMF17 - The optimum solution for critical applications Cleanrooms must maintain their purity levels in order to prevent contamination of products and processes taking place in a cleanroom environment. Gearboxes used in cleanrooms must meet special requirements and guarantee no particles are released into the environment. The gasket on the gearbox housing is responsible for ensuring lubricants and other particles inside the gearbox do not leak into the atmosphere. Thanks to its excellent adaptability and outstanding sealing performance, the FlatSeal™ HMF17 is the optimum solution for...

FlatSealTM Code Technology Ensuring the highest quality every step of the way Using a state-of-the-art calendaring process, HMF FlatSealTM gaskets are manufactured with the highest quality raw materials. Every batch of material must match precise specifications and is subject to rigorous inspection to ensure that only approved materials are used in production. To guarantee consistent high quality at all steps, a process control system monitors and controls the preparation of formulations, their blending operation, and the calendaring process that forms the material sheet from which a FlatSeal™...

Material Information Recommended temperature range: -100 °C to +130 °C / -148 °F to +266 °F Recommended pressure range: From high vacuum to a maximum of 100 bar / 1450 psi. The temperature and pressure recommendations in the graphs apply to gaskets 2.0 mm/0.08 inch thick that are used with raised face flanges. Higher stresses are possible when thinner gaskets are used. The recommendations are based on material characteristics and installation conditions. The information provided should therefore be considered cautious estimates rather than specific operational limits. Please contact your local...
