A full range of fiberglass functional felts—crafted with meticulous care, backed by uncompromising quality.
SBS/APP Modified Asphalt Waterproofing Membrane Base Felt
The base felt for SBS/APP‑modified bitumen waterproofing membranes is manufactured from high‑purity, alkali‑free glass fibers using a wet‑laid forming process. Specifically designed for SBS and APP‑modified bitumen waterproofing membranes, it exhibits excellent bitumen impregnation, superior tensile strength, and outstanding aging resistance. It bonds tightly with the modified bitumen, preventing delamination and adhesive failure, thereby effectively enhancing the membrane’s strength, toughness, and waterproofing performance. It is suitable for a wide range of building waterproofing applications, offering ease of installation and exceptional durability.

1. Product Description
The base felt for SBS/APP‑modified bitumen waterproofing membranes is manufactured from high‑purity, alkali‑free glass fibers using a wet‑laid forming process. Specifically designed for SBS and APP‑modified bitumen waterproofing membranes, it exhibits excellent bitumen impregnation, superior tensile strength, and outstanding aging resistance. It bonds tightly with the modified bitumen, preventing delamination and adhesive failure, thereby effectively enhancing the membrane’s strength, toughness, and waterproofing performance. It is suitable for a wide range of building waterproofing applications, offering easy installation and exceptional durability.
2. Core Explanation
• The asphalt exhibits excellent penetration, enabling rapid and complete impregnation of the modified bitumen; it bonds tightly with the substrate of the waterproofing membrane, with no delamination or adhesive failure.
• Excellent mechanical properties, with strong resistance to tensile stress, tearing, and fracture, effectively enhancing the overall load-bearing capacity of the waterproof membrane.
• Resistant to aging, UV radiation, and extreme temperatures, suitable for long-term outdoor use; it is less prone to degradation and embrittlement, thereby extending the service life of waterproof membranes.
• Compatible with both SBS and APP‑modified asphalt waterproofing membranes, offering excellent versatility; specifications can be customized to meet the specific requirements of various waterproofing projects.
