Fluoropolymers in
Sealants, O-Rings, Bearings & Gaskets

High performance bonding. Applied to ensuring seals stay sealed.

Air Intake Manifold Gasket

The purpose of the air intake manifold is to draw and funnel the air to the engine. The purpose of the gasket is to seal the gap between the manifold and the cylinder head - in an environment where the pressure and temperature are constantly changing.

Part failure means higher emissions coupled with poorer fuel economy and reduced engine performance.

3M™ Dyneon™ Fluoroelastomers play an important role in ensuring that the gasket will do the job and meet today's challenging standards.

Cylinder Head Gasket

This multi layer steel gasket seals the cylinder head surface to the engine block, avoiding leakage of engine oil or coolant into the cylinders as well as external leaks.

It is a critical sealing application of the combustion chamber which must withstand intense combustion pressure, hot engine coolant and oil. Consequences of the cylinder head gasket failing range from reduced power to severe engine damage.

3M™ Dyneon™ Fluoropolymers help to avoid such problems due to their excellent resistance to engine oils and coolants even at elevated temperatures.

Sealants

Expanded sealants made of PTFE with a microfibrillated internal structure for excellent stability are often used in flange sealing applications. This structure turns ordinary PTFE into a dimensionally strong, creep-resistant gasket material. The joint sealant is soft and conforms to worn or uneven surfaces. A melt adhesive strip holds the sealant in place for every assembly in the shop or field.

Flat Seals

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.
