Overview

          High temperature, flame resistance, fireproofing: what is the difference?

    High temperature adhesive tapes

    High-temperature adhesive tapes are used for their resistance in hot environments, generally from 150 °C. Thermal insulators (Kapton, glass cloth) can even withstand temperatures up to 316 °C.

    High-temperature tapes are used to mask and protect parts subjected to high temperatures during a cooking cycle, a passage in oven, for example.

     

    Flame resistant materials

    Flame resistance means that a material is non-flammable by nature: this is the case of concrete, steel, glass...

    • Combustibility: heat emitted by the complete combustion of a material
    • Flammability: quantity of flammable gas emitted by a material

    The French classification is applied for the furnishing materials, the others are classified according to the euroclasses and the standard EN 13-501-1.

    • M0 - non-combustible: stone, brick, cement, tiles, lead, steel, slate, ceramics, plaster, concrete, glass, rock wool, Staff
    • M1 - non-flammable combustible: composite materials, rigid PVC, mineral slabs of false ceilings, certain fireproof woods, certain fireproof polyesters, straw insulation
    • M2 - low flammability: wall-to-wall carpeting, particle board
    • M3 - moderately flammable: wood (including glued laminate, rubber flooring, polyamide carpet, wool
    • M4 - easily flammable: paper, polyester, polypropylene, mixed fiber carpet 

     

    Fire retardant tapes

    Fire retardant materials are chemically treated to become non-flammable or flame retardant (slow burning or self-extinguishing). Fireproofing is a process that delays or stops the spread of flames. Flame retardant products are key players in passive fire protection and play a crucial role in everyday life as well as in industry.

    A flame retardant tape has been coated with a flame retardant substance that protects it from burning or heating up. Many industries use flame retardant pre-products to increase the safety of manufactured products.

     

          What are the industry standards in terms of fire safety?

    Adezif offers a range of double-sided adhesive tapes for fire-resistant fastening applications with strict fire protection requirements.

    • UL94 : Flammability standard for plastics
    • FMVSS 302 : Automotive flammability standard
    • EN 81-58:2018-05 : Safety standards in construction
    • EN 13501-1 : Fire resistance of building materials
    • EN 13823 : French standard - reaction to fire tests of construction products
    • EN 45545 : Fire resistance standards for railways
    • FTP 2010 code - OMI : International Code For Application Of Fire Test Procedures (testing of parts and assemblies)

          Why a selection of halogen-free flame retardant products?

    Non-halogenated products are essential for passive fire protection:

    • Reduction of smoke emission and toxicity of fire gases
    • Smoke is the leading cause of fire-related deaths: 80% are caused by inhalation of toxic substances (cf. Inhalation injury as a prognostic factor for mortality in burn patients, El Helbawy et. Al, 2011.
    • The halogen-free products are designed in anticipation of future national and international regulations, which tend to reduce the use of certain halogenated products.

    The flame retardant products we offer comply with fire regulation standards and include halogen-free solutions that reduce smoke and gas toxicity.

          Fireproof liquid adhesives and sealants

    Fireproof glues and sealants play a crucial role in designing fire-resistant buildings and equipment.

    Fireproof glues are formulated to withstand extremely high temperatures and fire. They must be capable of enduring temperatures sometimes as high as 1000°C for extended periods without degrading or losing their adhesive strength. These adhesives are also resistant to chemicals, moisture, UV rays, and wear.

    Fireproof sealants, like the Sikaflex 821 FR special train PU fire sealant, are used to fill gaps between elements (doors, windows, etc.) to prevent or slow down the spread of fire. They are typically made from special materials such as silicone or elastomer. These sealants must be able to withstand fire for a prolonged period while maintaining their seal to prevent the spread of flames. They also need to be capable of accommodating structural movements, such as expansion and contraction, without losing elasticity.

    Fireproof adhesives and sealants are used in applications like fire doors, curtain walls, ventilation ducts, and smoke evacuation systems. Due to their ability to resist fire and protect structures from fire hazards, they are essential for fire safety in the industry.

    Like fireproof tapes, they must comply with fire safety standards and regulations, such as ASTM, UL, and EN standards.
