Insulation Jackets / High-Temp Canvas
Teflon (PTFE) Canvas
Non-stick PTFECompletely chemically inertFood conveyor suitable
Service temperature
Medium-high−200°C to +260°C
Main applications
Continuous service −65°C to +260°Ccompletely inert to strong acids and alkalis
- an FDA-approved non-stick
- chemically resistant composite fabric for expansion joints
- insulation jackets and food conveyors
Key Features
🧪
The highest chemical resistance available
Unreactive to virtually all acids, alkalis and organic solvents — ideal for corrosive gas and chemical exhaust lines
🌡️
Service from −200°C to +260°C
Stable performance across a broad range from cryogenic to high temperature
💧
Non-stick, low-friction surface
PTFE's characteristic non-stick surface — no dust or debris adhesion, suiting hygienic environments
🔇
Good vibration and noise absorption
The flexible PTFE-coated fabric structure isolates vibration at duct connections and prevents leakage

Applications
Chemical & petrochemical
- •Acid and alkali gas exhaust ducts
- •Exhaust connections on chemical reactors
Food, pharma & semiconductor
- •Hygienic exhaust duct joints
- •Cleanroom lines requiring a non-stick surface
Power & process plant
- •Exhaust ducts on flue gas desulphurisation (FGD) plant
- •Heat exchanger connections in corrosive service
Construction & HVAC
- •Kitchen and laboratory exhaust duct connections
- •Ventilation systems with chemical resistance requirements
Notes
- ※PTFE is inert to almost every chemical — more durable than stainless steel in corrosive gas environments.
- ※Above 260°C continuous service, consider silica canvas alongside.
- ※Thickness, coating method and reinforcement can all be customised — made to order after technical consultation.
