PTFE needle punched felt
Description:
PTFE needle punched felt are produced from 100% PTFE fiber which has been punched in three-dimensional structure. They have excellent features such as excellent flexibility, molding capability, high tensile strength, creep resistance, high and low temperature resistance, corrosion resistance and anti-aging. 100% PTFE filter material can meet requirements in hostile environments of temperature fluctuating and acid & alkali in all PH range. The lifespan of PTFE filter material will be guaranteed for over 4 years as long as the temperature is controlled under the maximum operating temperature.
Features:
• Be composed of 100% pure PTFE;
• Can operate at 240 ¡ãC continuously;
• Acid and alkali Resistance, corrosion resistance,have storong chemical stability (0-14 PH)
• Can be used under high humidity environment;
• Low shrinkage rate even if under high temperature,
• Aging resistance;
• No enviroment pollution
Applications:
• Combustion
• Coal burning boiler
• waste incineration
• carbon black producing
• Tio2 producing for fume treatment or dust collection
