DOGUSANQ FB870 TYPE l

DOGUSANQ FB870 TYPE I Block out: Premium Opaque Tensile Architecture Textile

DOGUSANQ FB870 TYPE I Block out, manufactured by Doğusan, is an advanced, high-performance PVC-coated fabric engineered specifically for the highly demanding Tensile Architecture sector where light blockage is required. With a robust total weight of 870 g/m² and a high-tenacity 1100 dtex polyester base, it provides an exceptional balance of structural strength and long-term protective qualities. The defining characteristics of this “TYPE I” architectural membrane are its opaque Block out nature, premium 2PVDF-1PVDF (SANQ PVDF) lacquering, Low Wick technology, strict fire retardancy, and absolute resistance to microorganisms.

Key Technical Features

• Block Out Capability: Designed as an opaque membrane to completely block light transmission, making it ideal for climate-controlled or event environments.

• Premium PVDF Surface: Treated with an advanced 2PVDF-1PVDF lacquering system (noted as SANQ PVDF) and a Glossy finish, offering superior environmental resistance, self-cleaning properties, and longevity.

• Low Wick Technology: Features “low wick” yarns that prevent moisture and dirt from traveling through capillary action within the base fabric, ensuring long-term aesthetic and structural integrity.

• Microorganism Resistance: Achieves a perfect “Degree 0, excellent” rating under the ISO 846-A standard, guaranteeing it will not degrade from fungal or bacterial growth.

• Comprehensive Fire Safety: Meets stringent global fire safety standards, including B-s2,d0 (EN 13501-1, listed as B-52,d0), M2 (92-507), B1 (DIN 4102-1, listed as 81), and NFPA 701.

• High Mechanical Strength: Delivers a reliable breaking strength of 3000 N/5cm and a tear strength of 300 N in both warp and weft directions, providing secure structural stability for tensioned applications.

• Extreme Weather Resilience: Engineered to function flawlessly in temperatures ranging from -40°C to +70°C, while maintaining a robust adhesion force of 100 N/5cm.

Primary Applications

• Tensile Architecture: Specifically optimized for permanent and semi-permanent architectural membranes, tensioned roofs, exhibition pavilions, and structural canopies where blocking sunlight and controlling temperature are essential.
