TPU base Film for lamination with fabric in Roofing and Building Structures
TPU base Film for lamination with fabric in Roofing and Building Structures
Overview
TPU (Thermoplastic Polyurethane) film, when laminated with various fabrics such as nylon, polyester, or nonwoven fabrics, creates a high-performance composite membrane ideal for roofing and building applications. This composite structure offers outstanding waterproofing, durability, flexibility, and optional breathability, making it suitable for lightweight roofs, green buildings, inflatable structures, mobile shelters, tents, awnings, and architectural membrane structures.
Structure Composition
-
Top Layer: TPU film (available in aliphatic or aromatic grades depending on UV resistance and durability requirements)
-
Middle Layer: Adhesive or direct melt lamination layer
-
Bottom Layer: Fabric (nylon, polyester, or nonwoven fabric)
Key Features
-
Excellent waterproof and airtight properties
-
Superior UV resistance and anti-aging performance
-
High tensile and tear strength for enhanced durability
-
Exceptional flexibility, easy to install and adaptable to various shapes
-
Optional high or medium breathability (MVTR customization available)
-
Eco-friendly, recyclable, and plasticizer-free
