B6665 (Type III, 1150g/m²), is a professional-grade, direct weldable double-sided PVC-coated fabric. This high-tenacity woven fabric is specially formulated to deliver TRAS 120 compliance, particularly for biogas plants processing mainly vegetal feedstocks. With excellent permeability resistance to methane and protective additives to guard against bacterial digestion, chemical, thermal and UV degradation, the membrane is designed to ensure reliable and durable performance. What's more, its flame retardant properties and high solar reflection performance ensure excellent safety and durability, while its electrodissipative surface finish provides superior protection against wear and tear. Suitable for both inner membrane (gas barrier) and outer membrane (structural skin) applications, B6665 is the ideal choice for your industrial biogas projects.
