In modern waterproofing applications, the choice of substrate plays a critical role in ensuring long-term performance, durability, and cost-efficiency. One such high-performance substrate is the High-Strength Compound Base (Composite Material), designed specifically for SBS/APP modified bitumen waterproof membranes.
What Is Compound Base Material?
The compound base is made by reinforcing recycled fabric with fiberglass mesh, creating a composite structure that delivers superior mechanical strength and stability. This innovative combination not only utilizes recycled materials for sustainability but also offers outstanding performance characteristics.
Key Features:
-
High Tensile Strength: The integration of fiberglass mesh significantly enhances the tensile strength in both machine direction (MD) and cross direction (CD), ensuring strong reinforcement for membrane applications.
-
Excellent Dimensional Stability: Maintains form and structure under heat and stress, reducing the risk of deformation.
-
Corrosion Resistance: Resistant to chemical corrosion, ensuring long-term durability in harsh environments.
-
Superior Water Resistance: Effectively repels moisture, a critical attribute for any waterproofing base layer.
-
High Porosity & Bitumen Saturation: Allows for easy penetration and bonding with bitumen, ensuring optimal performance in waterproof membranes.
-
Low Shrinkage (<1.0%): Maintains shape and performance even under extreme temperatures and humidity conditions.
