PTFE PRECISION MACHINING OF CUSTOM PLASTIC COMPONENTS
PTFE (Polytetrafluoroethylene)is a performance thermoplastic known for its chemical inertness & resistance to attack, low coefficient of friction, broad operating temperature range, excellent dielectric properties, thermal & electrical insulating, negligible water absorption and non-stick characteristic and among many others
PTFE resins have an upper service temperature of 500º F (260 C) and is one of the most widely used fluoroplastic material. PTFE mechanical properties are low compared to other advanced engineering plastics, but its properties remain useful over a temperature range of -400° F to 400° F forming its broad operating range suitable for many applications. PTFE can be used as low as - 436º F (-260 C ).
PTFE properties are often enhanced using a variety of fillers creating a PTFE compound, such as a 15 or 25% glass filled PTFE, to improve wear resistance, increase part stability, and improves creep strength and reduce deformation under load in comparison with virgin grade PTFE. For electrical insulators, the addition of glass filler has little impact on electrical properties.
PTFE GASKETS come in all shapes and sizes,Gaskets are an integral component of any device which requires the confinement of a gas or liquid. They compensate for the unconformity of mating surfaces. These surface irregularities may be minute or large depending on the purpose of the device but in all cases, the gasket is required to compensate for the difference while limiting the flow of fluid in either direction. Gaskets differ from seals in that gaskets are normally cut from sheets or rolls while seals are formed individually in their own configuration. A flat cut gasket is derived from material of specific thickness and to a configuration that is designed for a specific application
Expanded PTFE - EPTFE Gasket material is a soft and conformable material that is ideal for applications with limited bolt load torque available. Or in applications such as glass lined pipe where excessive bolt load will cause more problems than it will solve. If you have never touched this exceptional sealing material think of a dense marshmallow. It has the same chemical resistance and temperature range as any PTFE but it is soft and will effect a seal much quicker than regular PTFE gasket material
