PTFE (also called Telfon ) has excellent resistance to both acids and alkalis, restricted abrasion resistance, and has a maximum operating temperature of 500º F. The PTFE felts are costly due to an intensive production process. In return PTFE has an outstanding thermal and chemical stability.
Bulk Roll Goods: weight, thickness, density, roll width, and roll length are customized at your request.
Generally used for severe chemical environments at high temperatures
Excellent resistance to acids, alkalies, hydrolysis, oxidation, solvents
Abrasion resistance is generally superior to protein fibers but not as good as most synthetics
Requires a 20 verticalwire minimum support cage when used in tubular bag form
Expensive-excellent chemical and thermal resistance
Continuous operating temperature 500℉ (260°C)
