An operational temperature range of - 200°C to + 260°C, outstanding chemical resistance, lowest permeation rates and the ability to handle extensive pressure fluctuations where optimum performance is required.
Hoses made from 3M™ Dyneon™ Fluoropolymers are widely used in the chemical and associated industries thanks to their good chemical/corrosion resistance and ability to perform in broad temperature ranges. They also have non-stick properties and meet sanitary, FDA, and pharmaceutical requirements.
In general industry, hydraulic hose solutions based on 3M™ Dyneon™ PTFE are used in material handling equipment and mechanical engineering systems where petroleum-, synthetic- or water-based hydraulic fluids are applied. 3M™ Dyneon™ PTFE inner layer hose constructions are the answer when excellent temperature, chemical and permeation resistance at elevated pressure levels are required. In addition, the non-stick surface behaviour of 3M™ Dyneon™ PTFE prevents sedimentation on the hose surface resulting in long lasting, very high flow rates.
Tougher legal emission reduction requirements and economic drives towards optimizing corrosion protection in the chemical, pharmaceutical and associated industries, combined with a requirement for higher flexibility in use, have triggered a growing demand for 3M™ Dyneon™ Fluoroplastic liners in piping systems. Extruded or moulded pipe liners based on 3M™ Dyneon™ Fluoroplastics ensure reliable long lasting performance for extremely demanding applications.
High pressure hydraulic hose solutions based on 3M™ Dyneon™ PTFE are used in material handling equipment and mechanical engineering systems where petroleum-, synthetic- or water-based hydraulic fluids are present. Our inner layer hose constructions are the answer when excellent temperature, chemical and permeation resistance at elevated pressure levels are required. And let's not forget the long-lasting, very high flow rates that result from 3M™ Dyneon™ PTFE's non-stick capability that prevents sedimentation on the hose surface.
Our regular O-rings are standard solutions in the harsh and hot environments common in the chemical and petrochemical industry, as well as off shore productions, because they help optimize cost and ensure long life cycle performance. The broad range of 3M™ Dyneon™ Fluoroelastomers enables processors to meet specific industrial requirements perfectly. And if ultimate sealing performance, reliability and safety is required, 3M™ Dyneon™ Perfluoroelastomer compounds are ready to meet specific application requirements.
Flat static seals are used in many different flange applications. PTFE, PTFE Compounds or Fluoroelastomers are ideal in extremely demanding environments, thanks to their excellent chemical resistance combined with a broad temperature range, low vapour permeability, inertness and long-life product durability. They are used extensively in the chemical and petrochemical industry as well as in food & beverage, pharma and other hygiene applications.
Radial shaft seals are used to seal rotary engine or transmission components. Different shaft seal designs exist based on fluoroelastomer or PTFE lips. Some seal designs include an additional sealing lip in order to protect the primary sealing area from dust etc.
Automotive shaft seals (e.g. crankshaft and camshaft seals) in particular require ultimate durability under harsh conditions to last a car‘s lifetime. Aggressive lubricants from the engine side plus the protection of the system from outside dirt and dust result in one of the most demanding sealing applications.
The 3M™ Dyneon™ portfolio includes products which enable design engineers to develop state-of-the-art sealing solutions for today‘s demanding applications. Our products for shaft seal application provide good processability and superior metal bonding properties.
Used as flat flange or body gaskets, 3M™ Dyneon™ Fluoropolymers are excellent at sealing metal or glass pipes. That's why you will find them in many applications in the chemical processing and food and beverage industries.
Fluoropolymer applications in flat seals & gaskets
Thanks to their unique electrical, thermal and chemical resistance properties, heating cables with 3M™ Dyneon™ Fluoropolymer insulation are extensively used in the chemical, pharmaceutical and medical processing industries for column and vessel thermal management.
