 PTFE Expanded Gasket Data Sheet 

Because there are many types of PTFE gaskets, specific production is carried out according to requirements.

The PTFE expanded gasket is a highly adaptable sealing material designed for applications that require maximum chemical resistance and long-term reliability. Made from expanded polytetrafluoroethylene, the gasket features a soft and uniform microstructure that allows it to conform closely to flange surfaces, even when they are uneven, worn, or made from delicate materials. This flexibility ensures a tight, dependable seal with minimal bolt load, making it suitable for systems where traditional gaskets may struggle to achieve proper compression.

Because expanded PTFE is chemically inert, the gasket performs exceptionally well when exposed to aggressive media such as acids, alkalis, solvents, chlorine-based compounds, and a wide spectrum of industrial chemicals. ePTFE gasket non-aging nature prevents hardening or cracking over time, and the fiber-free composition eliminates contamination risks in sensitive processes. In addition to its chemical compatibility, the eptfe gasket maintains sealing integrity across a broad temperature range, ensuring stable performance under both cryogenic conditions and elevated heat. Its ability to establish a uniform seal under low tightening forces reduces the likelihood of flange damage and makes installation easier on glass-lined, ceramic, or plastic equipment. The gasket’s resistance to creep, cold flow, and moisture penetration further contributes to long service life, reducing maintenance intervals and operational downtime.

Whether used in pipelines, tanks, pumps, reactors, or general process equipment, the PTFE expanded gasket delivers consistent sealing performance and long-term durability. Its combination of softness, conformability, and chemical resistance makes it a universal sealing solution across chemical processing, water treatment, power generation, petrochemical operations, and high-purity production environments. As a versatile and reliable gasket material, it provides leak-tight performance where safety, cleanliness, and sealing stability are essential.
