High-performance modified PTFE sheets with silica filler. Improve wear resistance, dimensional stability & mechanical strength. Ideal for seals, gaskets, and chemical processing.
Modified PTFE Sheets with Silica – Superior Performance with Enhanced Durability
Modified PTFE (Polytetrafluoroethylene) with Silica is an advanced composite material that significantly improves the mechanical and thermal properties of standard PTFE. By incorporating high-purity silica filler, the material gains better dimensional stability, higher compressive strength, and enhanced wear resistance—making it ideal for demanding industrial applications.
Why Choose PTFE with Silica?
PTFE is widely known for its excellent chemical resistance, low coefficient of friction, and high-temperature performance. However, unfilled PTFE has limitations in load-bearing capacity and wear resistance. To address these issues, we offer modified PTFE sheets filled with silica, providing a balanced combination of low friction, enhanced hardness, and improved mechanical strength.
Key Features of PTFE with Silica:
*Improved Wear Resistance
Silica reinforcement increases the durability of PTFE in dynamic and abrasive environments.
*Enhanced Dimensional Stability
Better performance under mechanical load and pressure, with reduced cold flow.
*Excellent Chemical Resistance
Retains PTFE’s inertness and corrosion resistance, even in aggressive chemical environments.
*Low Friction Surface
Ideal for sliding applications requiring low wear and minimal lubrication.
*Wide Operating Temperature Range
Performs reliably from -180°C to +260°C.
Typical Applications:
Modified PTFE with silica is ideal for high-performance applications in industries such as:
*Chemical Processing – Seals and gaskets resistant to aggressive media.
*Pharmaceutical and Food Processing – FDA-compliant, inert surfaces for cleanroom use.
*Hydraulics and Pneumatics – Low-wear components such as piston rings and guide strips.
*Mechanical Engineering – Bushings, bearings, and wear pads in high-load systems.
*Aerospace and Automotive – High-performance seals and thermal barriers.
