Thermowell PTFE Coating
Polymech Engineering has manufactured a Thermowell PTFE Coating which is required to measure the temperature of highly corrosive processes. A thick PTFE Coating which covers all the wetted parts of the Thermowell. PTFE is an ideal material if the temperatures are not as high as it is resistant to most strong acids. By providing a thick coating to fit the Thermowell, you can protect your sensor and maintain control of your process temperature.
A Thermowell is a protective enclosure for temperature gauges and temperature sensors which enhance the life of the inserts. PTFE coatings for Thermowells can provide perfect protection against chemical influences by the right coating to choose right low porosity.
Solvay Solexis Halar ECTFE Coating Thermowell
Halar ECTFE is a partially fluorinated semi-crystalline polymer offering a unique combination of properties for highly demanding industries.
Outstanding chemical, permeation and fire resistance
Excellent weather ability
Excellent release properties
Good abrasion resistance
Halar ECTFE is widely used in anti-corrosion applications as a lining or in self-supporting constructions. It has excellent fire resistance properties and chemical resistance which make Halar ECTFE a product of the first choice in wire and cable applications or in communication cable.
Halar ECTFE coatings are distinguished from other fluoropolymer based coatings because of their exceptional surface smoothness, which inhibits buildup and accumulation of particles and metallic salts and reduces the formation of bioorganic films and bacterial colonies.
Permeation resistance is extremely important for long-term performance. Even if the coating material is not affected by direct contact with chemical substances, permeation through the coating can lead to metal corrosion, with service failure. Halar ECTFE coatings show very low permeability.
