Industrial Grade Non-Asbestos Gasket Sheet
Durable Aramid Fiber Sealing Material with Excellent Oil Resistance for Pipe Flanges and Heavy-Duty Equipment
Product Overview
This industrial-grade non-asbestos gasket sheet is engineered for reliable sealing performance in demanding mechanical and industrial environments. Designed with reinforced aramid fibers and oil-resistant elastomers, it delivers consistent compression and long-term durability for equipment operating under heat, pressure, and humidity.
Optimized for both Southeast Asia’s tropical climate and general industrial use, the material resists moisture absorption and surface degradation, helping reduce maintenance frequency and sealing failure in high-humidity regions.
Available thickness options range from 0.5 mm to 5.0 mm, allowing precise selection for various flange designs and sealing requirements.
