Biogas PVC Membrane Manufacturer & Supplier – DERFLEX
DERFLEX is a globally recognized biogas PVC membrane manufacturer specializing in high-performance coated textile membranes for renewable energy and environmental engineering applications. With more than 15 years of experience in PVC coated fabric manufacturing, DERFLEX supplies reliable and long-lasting PVC membranes for biogas digesters, gas holders, double-membrane roofs, and anaerobic fermentation systems worldwide.
What Is Biogas PVC Membrane?
Biogas PVC membrane is a gas-tight, flexible composite material made of high-tenacity polyester base fabric coated with specially formulated PVC compounds. It is designed to safely store and seal biogas produced during anaerobic digestion processes, typically containing methane (CH₄), carbon dioxide (CO₂), hydrogen sulfide (H₂S), and moisture.
Compared with traditional steel or concrete gas holders, PVC biogas membranes offer superior flexibility, corrosion resistance, lower installation cost, and reduced maintenance requirements, making them the preferred solution for modern biogas plants.
