Flame resistant polymer screws, nuts, bolts and washers, are fasteners that are made from polymers that have a low flammability and a high resistance to flames. They are used in a variety of applications where fire safety is a concern, such as in the construction, transportation, and defence industries, or in environments where the risk of fire is present. All fastener materials are graded on their flame resistance, this is outlined in the section below.
Flame resistant polymer screws, nuts, bolts, washers, and fasteners are an important component in many applications where fire safety is a concern. When components are paired with flame resistant fasteners, they may not only be meeting design specification but also meeting government legislation.
There are a variety of flame resistant polymers that can be used to make screws, nuts, bolts, washers, and fasteners, including polyphenylene sulphide (PPS), polycarbonate (PC), and polyetheretherketone (PEEK). These polymers are known for their low flammability and high resistance to flames.
Every polymer material is assigned a flammability rating. Our top flame resistant polymer material is PEEK, this is rated at ULV94 V-0. More information on PEEK can be found using the button below.
Flame resistant polymer screws, nuts, bolts, washers, and fasteners may be used in a variety of applications where fire safety is a concern, such as in the construction of buildings, vehicles, and other structures, as well as in the manufacture of safety equipment and in the operation of defence and transportation systems. They may also be used in the assembly of electrical and electronic components, such as batteries as well as in the manufacture of electrical insulation materials.
Flame-resistant polymer fasteners are made flame-resistant through the use of specialised chemical structures and additives that inhibit ignition and slow the spread of fire. The polymer's molecular composition is designed to resist breaking down under high heat, preventing combustion. Additionally, flame-retardant additives, such as halogens, phosphates, or metal hydroxides, are often incorporated to further enhance their resistance to fire by disrupting the combustion process. These materials may also promote the formation of a protective char layer when exposed to flames, which insulates the underlying material and reduces the release of flammable gases. This combination of inherent material properties and flame-retardant additives makes these fasteners effective in fire-prone environments.
Flame-resistant polymer fasteners offer crucial safety and performance benefits in environments exposed to heat and fire risks. These fasteners are designed to resist ignition and prevent the spread of flames, making them ideal for use in industries such as aerospace, automotive, electronics, and construction, where fire safety is paramount. In addition to their fire-retardant properties, these fasteners maintain excellent mechanical strength, thermal stability, and chemical resistance, ensuring long-term durability even in challenging conditions. They also reduce the risk of toxic fumes and smoke during a fire, enhancing overall safety in sensitive environments.
Yes - Flame resistant polymer fasteners are often chosen for their low flammability and high resistance to the spread of flames, as well as their other beneficial properties, such as corrosion resistance and good mechanical properties. They can help to improve the safety and reliability of equipment and structures in environments where the risk of fire is present, and they can help to prevent the spread of flames and reduce the risk of fire-related accidents.
