Moly-Filled PTFE
Moly-Filled PTFE (PTFE + MoS₂) – Enhanced Strength for Dynamic Sealing Applications
Saifex Industries supplies high-performance Moly-Filled PTFE (PTFE + MoS₂), a reinforced PTFE composite engineered for added strength, improved wear resistance, and superior load-bearing capability. The addition of molybdenum disulfide (MoS₂) enhances PTFE’s mechanical properties, making it ideal for dynamic sealing, high-speed sliding surfaces, and pressure-intensive applications.
We supply Moly-Filled PTFE sheets, rods, seals, bushes, rings, valve seats, and custom-machined components to industries across Bahrain, Kuwait, Oman, Qatar, Saudi Arabia, Iraq, and the United Arab Emirates.
Key Features
-
Higher mechanical strength than Virgin PTFE.
-
Improved wear resistance for continuous or high-speed movement.
-
Excellent lubrication and low friction due to MoS₂ additive.
-
Enhanced compressive strength and reduced deformation under load.
-
Suitable for dynamic sealing, high-pressure, and reciprocating applications.
Moly-Filled PTFE is a specialty PTFE composite reinforced with molybdenum disulfide (MoS₂), typically added in 5–15% concentrations. MoS₂ acts as both a solid lubricant and structural additive, improving PTFE’s mechanical integrity while maintaining its chemical inertness and low-friction properties.
This composite is engineered specifically for dynamic sealing and high-pressure environments, where Virgin PTFE or low-filled grades may deform under continuous load. The presence of MoS₂ enhances:
-
Tensile and compressive strength
-
Wear resistance under sliding or reciprocating loads
-
Thermal stability and heat dissipation
-
Dimensional stability and resistance to creep
Saifex Industries supplies Moly-Filled PTFE in the form of sheets, rods, bushes, rings, valve seats, thrust washers, guide rings, and CNC-machined precision parts, manufactured according to ASTM D4894, ASTM D4895, and ISO 12086.
Industries across Bahrain, Kuwait, Oman, Qatar, Saudi Arabia, Iraq, and UAE rely on our Moly-Filled PTFE for its unmatched performance in hydraulic systems, dynamic seals, pump components, aerospace applications, and heavy industrial machinery.
