What is flame retardant double wall heat shrink tubing

    The flame-retardant double-wall heat shrinkable tube has passed the UL224 flame retardant certification and can self-extinguish within 30 seconds of leaving the fire source to reach the VW-1 flame retardant level, which is often also called the V1 flame retardant level. Conventional flame-retardant double-wall heat shrink tubing means that the outer protective layer is flame-retardant, and the inner wall hot-melt adhesive is non-flame-retardant. Non-flame-retardant hot melt adhesive is generally transparent or beige. If the industry has very high flame retardant requirements, you can use military standard high flame retardant double-wall heat shrink tubing. The inner wall hot melt adhesive and outer protective layer are both flame retardant. The inner wall hot melt adhesive is white and the inner layer uses special flame retardant. For hot melt adhesive, the flame retardant grade of both the inner and outer layers can reach VW-1.

    Flame-retardant double-wall heat shrink tubing is a common type of protective material, and its main purpose is to prevent combustion. Many people have misunderstandings about flame-retardant heat shrink tubing. It does not mean that the product itself is non-combustible, but that it can prevent the spread of flames to a certain extent.

    The flame retardant double-wall heat shrinkable tube has a flame retardant grade of VW-1, which means it can extinguish itself within 30 seconds of leaving the flame, thereby achieving the purpose of flame retardancy. Double-wall heat shrinkable tubes are divided into two types: flame retardant and non-flame retardant. Flame-retardant double-wall heat shrinkable tubes add flame retardants during the production and ingredients process to achieve flame retardant effects. After leaving the combustion source, the flame-retardant double-wall heat shrinkable tube can extinguish itself in 30 seconds through its own flame-retardant properties, achieving a certain flame-retardant effect, preventing the spread of fire, and reducing personal injuries and property losses.

What is the function of flame retardant double wall heat shrink tubing?

    Flame-retardant double-wall heat shrinkable tubes are often used in industries that require flame retardancy, such as sealing of automotive wiring harnesses or pipelines, cable docking of household appliances, protection of condenser pipeline solder joints, sealing of waterproof and moisture-proof cable connectors, etc. , terminals, automobile wires, marine cables, wiring harnesses, metal tubes and other insulation, sealing, waterproof and moisture-proof protection, especially suitable for sealed and moisture-proof places.
