PTFE Cross-Laminated Film for Gas-barrier
PTFE Cross-Laminated Film for Gas-barrier is a non-porous, high-performance barrier composite made by laminating PTFE film with PTFE-coated fabric. This structure helps form a reliable gas-tight barrier for industrial sealing and protective liner applications.
PTFE Cross-Laminated Film for Gas-barrier is designed for demanding environments where gas leakage must be minimized. The PTFE Cross-Laminated Film provides excellent chemical resistance and long-term durability, while the fabric reinforcement adds handling strength and mechanical stability. With options based on different lamination types and film/fabric thickness combinations, it supports applications ranging from light-to-moderate gas sealing to more demanding dry gas sealing and heavy-duty duty sealing requirements.
PTFE Cross-Laminated Film for Gas-barrier also offers:
- Non-porous barrier performance for gas containment
- High durability with crack-resistant, flexible behavior
- Mechanical stability through PTFE-coated fabric reinforcement
- Chemical resistance suitable for harsh industrial media

Applications in the Expansion Joints Industry
PTFE Cross-Laminated Film for Gas-barrier is used in expansion joint systems to help protect against gas permeation and leakage in corrosive or high-contamination environments. In many expansion joint designs, this material supports gas sealing layers that help maintain system integrity during frequent expansion and contraction cycles.
Typical expansion joint use cases:
- Gas seal / barrier layer for non-metallic or hybrid expansion joint applications
- Protection for joint components exposed to corrosive gas environments
- Reliable gas containment where the joint must maintain performance under motion
In these systems, PTFE Cross-Laminated Film for Gas-barrier helps provide a stable sealing barrier that resists gas transmission while keeping durable, long-lasting coverage.
PTFE Cross-Laminated Film for Gas-barrier can be applied anywhere gas barrier protection, chemical resistance, and durable liner performance are required, such as:
- FGD (Flue Gas Desulfurization) Systems — barrier protection in corrosive flue gas environments
- Chemical Processing / Refining — protective gas barrier liners for ducts, casings, and sealed equipment interfaces
- Power Plants & Boilers — gas seal layers for components exposed to aggressive gases
- Industrial Ducting & Exhaust Systems — barrier lining where leakage control and corrosion resistance are critical
- Scrubbers & Emissions Control Equipment — gas containment and long-term durability in harsh operating conditions
