Flame-retardant PVC duct fabric is an advanced technical textile designed for manufacturing flexible ventilation ducts used in industrial environments. These specialized fabrics are engineered to provide excellent fire resistance, durability, flexibility, and long-term performance in demanding ventilation systems.
DER Factory is a professional manufacturer of flame-retardant PVC coated fabrics used in ventilation duct production. Our duct fabrics are widely used in mining ventilation systems, tunnel construction ventilation, underground engineering projects, and industrial air distribution systems.
Through advanced coating technology and strict quality control, DER Factory produces high-performance PVC duct fabrics that meet international fire safety standards while delivering excellent mechanical strength and environmental durability.
Flame-retardant PVC duct fabric is a reinforced textile material coated with fire-resistant PVC compounds. The base fabric is typically made from high-strength polyester yarns that provide structural reinforcement, while the PVC coating ensures airtightness, waterproofing, and fire resistance.
These materials are used to manufacture flexible ventilation ducts that transport fresh air, remove hazardous gases, and maintain safe working conditions in industrial and underground environments.
The flame-retardant properties of the material help prevent fire spread in ventilation systems, making it an essential safety component in mining, tunneling, and construction projects.
Flame-retardant PVC duct fabric is widely used in industries where ventilation safety and fire protection are essential.
Underground mining operations require reliable ventilation to remove dust, methane, and harmful gases. Flame-retardant ventilation ducts made from PVC duct fabric ensure safe airflow in these environments.
During tunnel excavation and underground infrastructure construction, flexible ventilation ducts supply fresh air and remove exhaust gases from heavy machinery.
Factories and industrial plants often require flexible ducting systems to transport air and control environmental conditions.
Subway construction, underground pipelines, and civil engineering projects rely on safe ventilation systems to maintain worker safety.
Portable ventilation ducts are commonly used in construction sites where temporary airflow management is required.

The material is engineered to meet international fire safety standards such as B1, NFPA or DIN flame retardant requirements.
Reinforced polyester fabric provides excellent mechanical strength for long ventilation duct life.
The PVC coating ensures effective air containment and efficient airflow through ventilation ducts.
The material remains flexible even in low temperatures, making it easy to install and transport.
PVC coating protects the fabric from moisture and environmental exposure.
Durable materials provide extended service life even in demanding underground environments.
