Description
Fiberglass compound base mat is one kind of base mat of poly-cotton nonwoven and fiberglass mesh combination. It ismade by compounding some density fiberglass when producing non-woven, through drying in high temperature and finalizing technics.It is the basic mat for producing APP/SBS waterproof material.
- Widely used in waterproof material, such as waterproof membrane (SBS/APP modified bitumen) and asphalt shingle.
- It has high tensile strength and competitive price, no any shrinkage in producing.
- The weight for every type can decrease or increase accoring to customer requirement.
Product Description:
4×4 Compound Base Mat is a composite reinforcement material made by combining a 4×4 fiberglass leno weave scrim with polyester nonwoven layers. This specialized structure provides excellent tensile strength, tear resistance, and dimensional stability, making it ideal for use in modified bitumen waterproofing membranes.
Key Features:
-
4×4 Leno Fiberglass Scrim: Offers superior strength and tear resistance in both machine and cross directions.
-
Composite Construction: Integrates fiberglass scrim and spunbond polyester mat for enhanced mechanical properties and flexibility.
-
Excellent Compatibility: Ensures strong adhesion with SBS and APP modified bitumen.
-
Thermally Stable: Maintains integrity under high-temperature lamination and coating processes.
-
Lightweight and Durable: Provides reinforcement without significantly increasing membrane weight.
-
Smooth Surface: Enhances bitumen coating uniformity and processing efficiency.
Applications:
-
SBS/APP Modified Bitumen Waterproofing Membranes
-
Roofing and underground waterproofing systems
-
Infrastructure waterproofing such as bridges and tunnels
-
Base reinforcement for compound felt or multi-layer membranes
