Industrial PVC Membrane – High-Performance Coated Textile Solutions
DERFLEX is a professional manufacturer and global supplier of industrial PVC membrane, specializing in coated textile materials designed for demanding industrial, architectural and environmental applications.
With decades of experience in PVC coating technology, DERFLEX industrial PVC membranes combine mechanical strength, long-term durability and excellent resistance to weather, chemicals and UV exposure, making them a trusted solution worldwide.
What Is Industrial PVC Membrane?
Industrial PVC membrane is a composite coated textile material produced by applying polyvinyl chloride (PVC) coatings onto a high-tenacity polyester base fabric. Through advanced coating and lamination processes, the membrane achieves superior tensile strength, flexibility, waterproofness and surface performance.
Compared with conventional fabrics or films, industrial PVC membranes are specifically engineered for long-term outdoor and industrial use, where resistance to mechanical stress, harsh environments and continuous exposure is essential. 
DERFLEX Industrial PVC Membrane Structure
High-Tenacity Polyester Base Fabric
The foundation of every DERFLEX industrial PVC membrane is a high-tenacity polyester base fabric. This reinforcement layer provides excellent tensile strength, dimensional stability and tear resistance, ensuring structural reliability under load.
- Warp and weft yarns with high breaking strength
- Low elongation under tension
- Consistent fabric construction for uniform coating
PVC Coating System
The PVC coating layer determines the membrane’s functional performance. DERFLEX uses customized PVC formulations to meet different industrial requirements, including flexibility, chemical resistance and flame retardancy.
- Knife-coated or laminated PVC layers
- Excellent waterproof and airtight properties
- Strong adhesion between fabric and coating
Surface Treatments
Optional surface finishes further enhance performance and service life. These treatments improve resistance to UV radiation, dirt accumulation, microbial growth and chemical attack.
- PVDF top coating for self-cleaning surfaces
- Acrylic coating for cost-effective durability
- Anti-fungal and anti-bacterial treatments

Industrial PVC membranes from DERFLEX offer excellent tensile and tear strength, allowing them to withstand wind loads, internal pressure and mechanical stress in large-span and heavy-duty applications.
Weather & UV Resistance
Designed for long-term outdoor exposure, DERFLEX PVC membranes maintain flexibility and appearance even under intense UV radiation, rain, snow and temperature variations.
Chemical & Corrosion Resistance
PVC membranes exhibit strong resistance to acids, alkalis, salts and industrial pollutants, making them suitable for environmental engineering, wastewater treatment and chemical storage.
Excellent Processability
DERFLEX industrial PVC membranes are compatible with high-frequency welding, hot-air welding and other fabrication techniques, ensuring reliable seams and airtight connections.
Main Application Areas
Architectural Membrane Structures
Industrial PVC membranes are widely used in tensile architecture such as stadium roofs, exhibition halls, canopies and shade structures. Their lightweight nature and high strength allow innovative architectural designs with large spans.
Environmental Engineering
In environmental protection projects, PVC membranes are used for biogas digesters, wastewater tank covers, sludge storage and odor control systems.
Industrial Storage & Containment
PVC membranes provide reliable waterproof and chemical-resistant barriers for industrial storage tanks, reservoirs and secondary containment systems.
Transportation & Logistics
Used in truck tarpaulins, container covers and industrial curtains, PVC membranes protect goods from weather and mechanical damage during transport.
Agriculture & Livestock
In agricultural applications, industrial PVC membranes are used for silage covers, manure storage, greenhouse roofing and livestock shelters.
