Modified PTFE Sheet S611 (Glass Fibre) Description
Modified PTFE Sheet S611 (Glass Fibre) is a material engineered for industrial applications. It combines the chemical resistance, non‐stick properties and thermal stability of PTFE with glass fibre reinforcement. This formulation provides measured mechanical properties for conditions subject to high stress.
The S611 variant demonstrates dimensional stability, impact resistance and reduced thermal expansion. It retains the fundamental characteristics of PTFE, such as resistance to harsh chemicals and high temperatures (up to 260°C); the glass fibre reinforcement increases the material’s structural integrity, thereby enabling it to endure elevated mechanical forces over extended periods.
Modified PTFE Sheet S611 (Glass Fibre) Applications
·
Chemical Processing: Employed in gaskets, seals and liners for equipment exposed to aggressive chemicals, acids and solvents.
·
Aerospace: Utilised in sealing, insulation and structural components operating in high‐temperature environments; this meets the requirements in aircraft systems.
·
Automotive: Suitable for engine seals, exhaust systems and fuel systems where temperature resistance and mechanical strength are required.
·
Electronics: Deployed as insulation, gaskets and seals in electrical systems owing to its high dielectric properties.
·
Food Processing: Applied in food‐grade systems because of its non‐stick and corrosion‐resistant nature and ease of cleaning.
