Key Features
-
Improved wear resistance compared to Virgin PTFE.
-
Higher compressive strength and reduced cold flow (creep).
-
Enhanced dimensional stability under pressure and temperature fluctuations.
-
Resistant to acids, alkalis, solvents, and aggressive chemicals.
-
Available in 15% & 25% Glass-Filled PTFE (Reinforced PTFE) grades for different applications.
Glass-Filled PTFE is a high-performance composite engineered by combining pure PTFE (Polytetrafluoroethylene) with glass fibers, typically in concentrations of 15% or 25%. The addition of glass significantly improves PTFE’s mechanical strength, stiffness, and resistance to deformation, making it ideal for critical sealing, wear, and structural applications.
While Virgin PTFE is chemically inert and low-friction, it can deform under load due to cold flow. Glass reinforcement reduces this issue, giving Glass-Filled PTFE its signature dimensional stability and load-bearing capability, especially under continuous pressure or elevated temperatures.
Saifex Industries supplies Glass-Filled PTFE Sheets, Rods, Tubes, Rings, Gaskets, Valve Seats, Bearings, Bushes, and Custom Machined Parts, manufactured according to ASTM D4894, ASTM D4895, and ISO 12086 standards.
Engineers widely prefer Glass-Filled PTFE in valves, pumps, compressors, hydraulic systems, and chemical processing equipment where durability and wear performance are essential.
Our Glass-Filled PTFE products are trusted across Bahrain, Kuwait, Oman, Qatar, Saudi Arabia, Iraq, and UAE, where industries demand reliable, chemically resistant, and dimensionally stable polymer solutions for harsh operating conditions.
