Description
Product Description:
250g Reinforced Spunbond Polyester Mat is a high-strength, nonwoven polyester fabric specially engineered for modified bitumen waterproofing membranes. It integrates longitudinal fiberglass strands between two spunbond polyester layers, then reinforced by needle punching. This structure significantly improves tensile strength, dimensional stability, and processing speed in membrane production lines.
Key Features:
-
Enhanced Tensile Strength: Fiberglass reinforcement provides excellent mechanical durability.
-
Stable Structure: Resists shrinkage, deformation, and elongation under thermal stress.
-
Improved Production Efficiency: Allows higher speed in waterproofing membrane production.
-
Uniform Surface: Ensures optimal bonding with bitumen during lamination.
-
Wide Temperature Resistance: Maintains integrity under hot asphalt and cold environments.
-
High Compatibility: Ideal for SBS and APP modified bitumen systems.
Applications:
-
High-performance SBS/APP Modified Bitumen Waterproofing Membranes
-
Roofing and underground waterproof systems
-
Bridge, tunnel, and infrastructure waterproofing
-
Base layer for high-durability composite mats

Filament Reinforced Polyester Mat (Felt). In the traditional production process of filament polyester mat, manufacturers introduce fiberglass between two layers of fiber mesh. They arrange the fiberglass longitudinally at a certain distance and then reinforce it through acupuncture. The addition of fiberglass provides better tensile properties, enabling the membrane to improve production speed on the waterproof membrane production line while maintaining its physical properties. At the same time, the process enhances the thermal dimensional stability of the filament polyester mat to some extent. Currently, the international market widely uses this polyester mat, and the Chinese market has gradually accepted it as well.
