Supply PTFE Coated Fabric to Customize PTFE air duct
What is PTFE Air Ducting?
PTFE air duct is a kind of flexible hose which is chemical corrosion resistant and conductive. PTFE air duct made of two layers of PTFE coated fiberglass fabric supported and reinforced by spiral metal keel. PTFE coated gives this fabric material several excellent advantages such as heat resistance up to 260℃ for continuous use, chemical corrosion resistance, aging resistance and flame retardant. Outside spiral metal keel offers extremely secure clamping design of wall and gives external wear protection. PTFE air duct is mainly used for suction and discharge of corrosive chemicals such as strong acids, highly aromatic solvents, chlorinated or oxidizing solutions, and aromatic hydrocarbons, etc..For welding waste gas extraction, air conditioning and ventilation equipment extraction and conveying; For steam, smoke and industrial dust removal and suction.
