MelaminE Fibers
Properties
Melamine fibers are synthetic fibers in which the fiber-forming substance is a synthetic polymer composed of at least 50% by weight of a cross-linked melamine polymer.
Melamine fibers have low thermal conductivity, excellent flame resistance, are self-extinguishing and exhibit excelllent dimensional and heat stability with a continuous operating temperature of about 400°F (200°C). These properties make melamine fibers a good choice for flame resistant apparel.
They can be processed with standard textile equipment and are sometimes blended with commodity fibers and other heat resistant synthetic fibers such as aramid fibers.1
COMMERCIAL Melamin Fibers
Basofil was the only commercial melamin-based fiber. It was developed by BASF AG in the 1990’s.1 Due to limited demand and high cost relative to other fibers, it has been discontinued.
Applications
Melamine fibers can be used for fire blocking fabrics like aircraft seating and upholstery in high-risk occupancies, protective clothing and gear for firefighters, mattresses, and for home furnishings that are compliant with 16 CFR1633 in high-risk occupancies. Other potential applications include tire sealants, heat resistant gloves, insulating thermal liners, specialty flame resistant and electrical papers and filter medias of high capacity and efficiency.
