Portwest MV71 Trousers: Multi-Norm Shield, Modaflame™ Thermal Protection, and Industrial Watertightness

The MV71 trousers are high-level protective garments designed for critical risk environments, such as the petrochemical industry, offshore platform operations, and process plants with exposure to electric arc or flames. Integrated into the Modaflame™ Rain line, these trousers combine the inherent flame-retardant property of their fibers with a waterproof and breathable barrier. This duality allows the operative to remain protected against thermal and climatic risks simultaneously, guaranteeing safety without sacrificing operability in stormy or severe rain conditions.

Why is this equipment vital for the operation?

• Multi-Norm Protection Technology (Inherently Flame Retardant): Unlike chemically treated fabrics, Modaflame series fibers possess permanent flame-retardant properties that do not degrade with washing. This feature ensures that the operative has constant protection against radiant, convective, and contact heat, as well as against the dangerous effects of an electric arc, throughout the garment's useful life.
• Hydrophobic and Hydrocarbon Barrier: In addition to its ability to block water entry (Class 3 watertightness), the fabric exhibits exceptional resistance against chemical and oil impregnation. This quality is vital in refinery environments, where contact with industrial fluids is common, preventing the garment from becoming a vehicle for fire propagation.
• Electrostatic Charge Management (Antistatic): The design includes conductive threads in its textile structure to dissipate static charge. This prevents energy accumulation in environments with a risk of explosive atmospheres (ATEX), complying with the strictest industrial electrical safety regulations.

Structure Analysis and Technical Details

The MV71's architecture is robust and functional, with high-frequency sealed seams that ensure total watertightness. The cut is generous to allow its use over additional thermal layers, and its ergonomic design reduces snagging points on rotating machinery.

• Base Material: Modaflame Rain fabric (98% Flame Retardant Polyester, 2% Antistatic Carbon Fiber) with breathable PU coating.
• International Certifications: EN ISO 14116, EN 1149-5, EN 13034 (Type 6), EN ISO 20471 Class 2, and EN 343 Class 3:3.
• Operational Configuration: Ergonomic elastic waistband for a firm fit, side openings protected with concealed zippers, adjustable hems with flame-resistant snap fasteners, and full-coverage design.
• Environmental Resistance: Fabric treated to resist UV fatigue, maintaining fluorescent properties and mechanical integrity in extreme field conditions.
