Non-metallic Expansion Joint Fabric
Non-metallic Expansion Joint Fabric is a PTFE-based composite fabric designed for expansion joint liners and membranes. It combines PTFE skived film / PTFE film with glass fiber cloth, creating a flexible, durable, and chemical-resistant material system for expansion joint components.
Why Choose Our Fabric
This non-metallic fabric is selected for expansion joint projects where corrosion resistance and performance stability matter. The PTFE surface characteristics support low adhesion / non-stick behavior, which helps reduce sticking and material buildup in service.
Key advantages include:
- Chemical-resistant performance for aggressive industrial environments
- Flexible and lightweight composite for easier fabrication and installation
- Stable liner/membrane function under expansion movement and service cycles
- Good handling and tailoring for lining and membrane applications

Applications in the Expansion Joint Industry
Non-metallic Expansion Joint Fabric is widely used as a core material in expansion joint solutions where corrosion resistance and flexibility are critical. It is commonly applied in fabric-based expansion joint components such as:
- Expansion joint liners / membranes
- Expansion joint bellows fabric layers (depending on joint design)
- Lining materials for aggressive chemical services
- Components requiring PTFE surface characteristics (low adhesion and chemical compatibility)
Because this is a PTFE/glass fiber composite, it is often considered for industries that require chemical resistance and reliable flexible composite performance, such as:
- Chemical processing & chemical plants
- Pulp & paper
- Water & wastewater treatment
- Mining & metallurgy
- Power generation & utilities
- Industrial ducting / flue gas systems (when chemical resistance is required)
