Clothing that protects against fire-related risk factors must meet specific safety standards defined in norms. There are different levels of protection and various standards, but the goal is always the same: to protect the health and life of an employee exposed to a hazardous work environment.

The multitude of standards, depending on the industry and levels of protection, means that different products are recommended for specific applications. However, the quality requirements are very similar: the material must not continue to burn after the ignition source is removed (it must be self-extinguishing), there should be no afterglow, and no heat accumulation. For higher classes of protection, it also means maintaining the functionality of accessories like zippers, allowing them to be easily unzipped to remove the garment. We supply accessories for all types of fire hazards.

Fire Retardant Metal Zippers

The most popular and trusted variant in this category are zippers whose construction is based on two key elements: metal, brass teeth and a tape made of meta-aramid fibers. Brass, thanks to its high melting point (approx. 900-940°C) and high mechanical strength, ensures the structural integrity of the zipper even in extreme conditions.

The meta-aramid tape, in turn, is a specialized synthetic fiber that does not melt, drip, or sustain combustion upon contact with a flame, but instead chars, creating a protective barrier. It is the synergy of these two components that determines the reliability of the entire zipper.

Fire Retardant Plastic Zippers

This is an innovative equivalent to metal zippers; the plastic elements are molded from a specially modified material, which makes it possible to achieve flame-retardant parameters at a level similar to that of metal zippers.

As with metal zippers, the key element remains the tape made from aramid fibers, which guarantees that the base of the zipper will not melt and will not sustain combustion. The combination of this proven tape with innovative, flame-retardant plastic elements creates a modern alternative to heavier metal zippers.

+Advantages

  • ›Self-extinguishing
  • ›Lightweight
  • ›Easy to clean
  • ›Don't accumulate heat
  • ›Slider: metal or FR resin

−Disadvantages

  • ›Lower transverse strength

D8 Fire Retardant Open-End Molded Zipper

A size 8 molded zipper with teeth made of flame-retardant plastic on an aramid fiber tape. The zipper is equipped with a plastic flame-retardant slider and puller; the absence of metal parts reduces the risk associated with metal heating up and related burns. The zipper is suitable for use in clothing for electricians.

Frequently Asked Questions

Fire retardant zippers must meet specific safety standards to protect workers in hazardous environments. The quality requirements are clear: the material must not continue to burn after the ignition source is removed (self-extinguishing), there should be no afterglow, and no heat accumulation. For higher classes of protection, it's crucial that accessories like zippers maintain their functionality, allowing them to be easily unzipped to remove the garment quickly in emergency situations. We supply accessories for all types of fire hazards, ensuring both safety and user comfort in the harshest working conditions.
Fire retardant metal zippers are the most popular and trusted variant in this category, based on two key elements: metal brass teeth and meta-aramid fiber tape. Brass, with its high melting point (approximately 900-940°C) and high mechanical strength, ensures structural integrity even in extreme conditions. The meta-aramid tape is a specialized synthetic fiber that doesn't melt, drip, or sustain combustion upon flame contact; instead, it chars, creating a protective barrier. The synergy of these components determines the zipper's reliability. They're durable, strong, and self-extinguishing, making them ideal for the most demanding applications.
Fire retardant plastic zippers are an innovative equivalent to metal zippers, with elements molded from specially modified material that achieves flame-retardant parameters similar to metal zippers. Key advantages include being self-extinguishing, lightweight, easy to clean from contaminants, and not accumulating heat – a critical safety feature. The slider can be metal or made from high-performance reinforced resin that's also flame retardant. Combined with aramid fiber tape that won't melt or sustain combustion, these zippers offer a modern alternative to heavier metal zippers, particularly suitable for applications like electrician workwear where avoiding metal heat accumulation is important.
Both types use aramid fiber tape as the base, but differ in their teeth construction and performance characteristics. Metal zippers offer superior transverse strength and durability, making them ideal for heavy-duty applications, but they're heavier and metal elements can accumulate heat, posing burn risks. Plastic fire retardant zippers are lighter, don't accumulate heat, and are easier to clean, making them safer for electricians and applications where heat accumulation is a concern. However, they have lower transverse strength. The choice depends on your specific application requirements, working conditions, and the level of mechanical stress the zipper will face.
Our fire retardant zippers meet various international safety standards depending on the application. We supply zippers compliant with ISO-EN14116 and NFPA 2112/2113 for general workwear requiring flame resistance. For firefighter turnout gear, our M8 NOMEX zippers meet ISO-EN469 and NFPA1975 standards, trusted by fire departments worldwide. Our plastic accessories meet UL94 standard, class V-0 requirements. We offer flame-retardant treated options with wash resistance of approximately 20 washes, as well as permanent aramid-based solutions. Different protection levels and industry requirements mean we can recommend the most appropriate product for your specific application.
