Non-Asbestos Latex Fiber Gasket Sheet for Industrial Sealing – Heat, Oil, and Pressure Resistant for Mechanical Equipment and Insulation Applications
When it comes to industrial sealing solutions, the non-asbestos latex fiber gasket sheet stands out as a versatile choice, available in thicknesses from 0.5mm to 5mm. A smart selection tip: opt for the thinnest variant that meets your specific application needs. This approach not only cuts down on costs but also guarantees top-notch performance in sealing tasks.
Core Composition & Manufacturing Craft
This innovative gasket sheet is a blend of aramid fiber, non-asbestos mineral fiber, synthetic fiber, and oil-resistant synthetic rubber. Its production involves two key steps: hot-roller compression and vulcanization. These processes work together to create a gasket with a robust internal structure, high density, and impressive physical properties, laying a solid foundation for its reliable performance.
Model Classification by Temperature Resistance
The product is categorized based on its peak temperature tolerance (indicated by specific numbers), ensuring there’s a suitable option for various high-temperature working environments.
Contact Medium | Performance |
Oil | High resistance, maintains integrity and sealing performance |
Water | Does not degrade, suitable for wet environments |
Petrol | Resistant to corrosion and swelling |
Natural Gas | Prevents leakage, reliable for gas - related applications |
