Ptfe seal - Import export

We develop and manufacture special seals for power stations, for the chemical and petrochemical industries, for machinery and pipeline construction. In other words, seals that provide the greatest possible reliability even under extreme operating conditions (pressure, heat, cold, aggressive media) – at temperatures from -200 to +1.000 °C. Product Range: - DVGW tested, see separate brochure - Punched, cut seals - Plates, foils - Semi-finished items - Form articles Benefits: - Highest chemical resistance - Insoluble and does not swell in organic or anorganic solvents - Resistant to the weather - Temperature range -190 to +250 °C - Highly anti-adhesive, does not stick - Resistant to hydrolysis Common fillers: - Quartz - Glass - Carbon / Graphite - Bronze - or without filters Fillers reduce the cold flow, lead to higher resistance to temperature and media, improve thermal conductivity and increase resistance to abrasion and pressure levels.

Using the materials mentioned, HEUTE+COMP. manufactures sealing elements and O-ring supports according to your specifications. PTFE support rings prevent high pressures from extruding O-rings into sealing gaps and damaging the rings as a result. Due to its cold flow characteristics and high degree of abrasion, pure PTFE is only conditionally suitable for sealing. Accordingly, a wide range of PTFE compounds have been developed to account for all involved parameters. Temperature Media influence Pressures Sealing gaps Assembly conditions Additionally for dynamic applications: Material and surface of the sliding counterpart Speed The technique used to process a material also influences its properties. For instance, a material filled with glass can be made gas-tight through special heat treatment. For this reason, our team offers consultancy early on during the development phase in order to select appropriate materials for your application.

PTFE thread sealing rings from HEUTE + COMP. and SIEPMANN + NEUFELD are made of a special, brown compound capable of secure sealing without the need for hemp or PTFE tape. Components furnished with sealing rings are simply joined and allow repeated mounting as well as corrective rotation. Having proven itself millions of times in the past, this system’s reliability makes it suitable for large production quantities as well as special constructions. KTW and WRC approval have been issued.
