Polyurethane (PU) Coated Cloth - Fire & Smoke fabric
Vitcas Polyurethane (PU) Coated Cloth is a specialised high-performance Fire & Smoke fabric engineered for superior gas impermeability while maintaining light transmission. The cloth is coated with a specially formulated polyurethane, micronised aluminium-filled polymer, providing a heat-reflective surface and maintaining low air permeability at elevated temperatures. This advanced, halogen-free and fire-resistant material is designed to withstand extreme temperatures of up to 550°C (1020°F) in continuous operation and 600°C (1110°F) during short-term exposure, ensuring robust and reliable performance in critical applications.
Key Features:
Gas Impermeability: The polyurethane coating, integrated with the aluminium-filled polymer, ensures the fabric is completely impermeable to gases, making it indispensable in fire safety and emergency applications, while allowing light to penetrate for operational visibility.
Halogen-Free & Non-Toxic: Manufactured without halogens, the fabric is non-toxic and non-irritating, ensuring safe usage in various sensitive environments.
Fire Resistance: Classified according to BS EN 13501-1:2018 as B-s1, d0. The PU Cloth is manufactured from high-quality glass fibre with a durable polyurethane coating, provides excellent resistance to fire, heat and smoke, with very limited smoke production (s1) and no flaming droplets (d0).
Thermal Stability: The cloth exhibits continuous temperature resistance up to 550°C (1020°F) and can endure 600°C (1110°F) for short bursts, making it suitable for use in extreme thermal environments.
Enhanced Durability: The PU coating is resistant to 180°C (360°F) and significantly increases the fabric's resistance to abrasion, punctures, and mechanical wear, offering prolonged service life in demanding conditions.
Applications:
Firefighting: Utilised extensively in firefighting equipment for fire, heat, and smoke protection, safeguarding both personnel and critical equipment.
Automotive Industry: Applied in thermal insulation, soundproofing and fireproofing of vehicles, offering a durable solution that meets safety and performance standards.
Aerospace: Used as thermal insulation and structural reinforcement in aircraft components, where lightweight materials with high heat tolerance are essential.
Industrial Manufacturing: Ideal for heat-resistant curtains, welding blankets, and protective barriers against sparks, molten metal, and high temperatures in industrial settings.
Personal Protective Equipment (PPE): Integrated into fire-resistant garments such as gloves, aprons, and overalls to protect workers in hazardous environments.
Electrical Insulation: Provides insulation for electrical cables and wires, protecting them from fire risks and high heat in industrial and commercial applications.
Construction: Deployed in fireproof curtains, partitions, and protective coatings within construction projects to meet fire safety regulations.
Marine Industry: Utilised in shipbuilding and insulation systems, providing essential fire resistance and safeguarding against fire hazards and smoke infiltration in engine rooms, bulkheads, and control systems.
Medical Sector: Incorporated into the production of fire-resistant surgical drapes, gowns, and other medical textiles, ensuring compliance with safety standards in healthcare settings.
Motorsports: Utilised in fire-resistant gear for motorsports, offering critical protection and safety in extreme heat and high-risk racing conditions.
The fabric is manufactured from woven glass fibre and coated with a specially formulated polyurethane containing micronised aluminium. This produces a lightweight, heat-reflective surface while maintaining low air permeability at elevated temperatures.
Question
What is the continuous temperature limit of the PU-coated fiberglass cloth?
Answer
The continuous temperature resistance is up to 550°C. This is the figure to use when assessing prolonged exposure. The material can withstand a higher temperature for short periods, but that short-term rating should not be treated as its normal continuous operating limit.
Question
Can the PU-coated cloth withstand 600°C?
Answer
Yes, but only during short-term exposure. The short-duration temperature limit is 600°C, while the continuous operating limit is 550°C. Both the normal temperature and any temporary peaks should be considered before selecting the cloth for a particular specification.
Question
What fire classification does the PU-coated cloth have?
Answer
The material is classified as B-s1, d0 in accordance with BS EN 13501-1:2018. This classification confirms very limited smoke production under the stated test conditions and no flaming droplets. It should not be interpreted as a specific fire-resistance period for a complete installation or assembly.
Question
Is the polyurethane cloth impermeable to gases?
Answer
Yes. The polyurethane and aluminium-filled coating provides gas impermeability while still allowing light transmission through the fabric. This combination distinguishes it from an uncoated glass fibre cloth. The final performance of any completed assembly will also depend on its joins, edges, fixings and overall construction.
Question
Does the PU coating improve resistance to damage?
Answer
Yes. The polyurethane coating increases resistance to abrasion, punctures and mechanical wear, helping the fabric withstand handling and repeated use. The coating itself has a stated temperature resistance of 180°C, which is separate from the higher continuous and short-term temperature ratings confirmed for the complete coated cloth.
Question
Is the coated glass fibre cloth halogen-free?
Answer
Yes. The cloth is manufactured without halogens and is described as non-toxic and non-irritating. These material properties can help when comparing coated fabrics, but any project-specific handling, workplace or protective requirements should still be assessed separately.
Question
How is the PU-coated glass fibre cloth supplied?
Answer
The cloth is 1,000mm wide and 0.45mm thick and is sold by the metre. A complete roll contains 50 metres. Enter the required number of metres when ordering and include sufficient allowance for cutting, overlaps, seams or edge finishing where these form part of the intended design.
