In the world of waterproofing materials, choosing the right carrier layer is critical for ensuring performance, longevity, and cost-effectiveness. Among the available options, staple fiber polyester mat stands out as an ideal base material for modified bitumen waterproof membranes.
At Guanlong, we specialize in producing high-performance staple fiber polyester mats with outstanding physical and chemical properties. Whether you are manufacturing SBS/APP modified bitumen membranes or seeking a stable reinforcement layer for composite waterproofing solutions, our polyester mat delivers optimal results.
Key Features of Guanlong Polyester Mat
-
Excellent Tensile Strength: Maintains structural integrity under stress, ensuring membrane stability.
-
Good Expandability: Supports the movement of the waterproof layer under environmental or mechanical stress.
-
Superior Heat Stability: Resistant to deformation under high processing and application temperatures.
-
Outstanding Aging Resistance: Performs reliably over long periods, even in harsh weather conditions.
-
Efficient Impregnation: Ensures uniform saturation of asphalt or modified bitumen for consistent performance.
-
High Corrosion Resistance: Resists degradation from chemicals and environmental exposure.
Because of these characteristics, Guanlong staple fiber polyester mat is the first choice for producing modified waterproof membranes used in roofing, foundations, tunnels, and infrastructure projects.
