Melamine Fiber
Melamine fiber is a manufactured fiber in which the fiber-forming substance is a synthetic polymer composed of at least 50% by weight of a cross-linked melamine polymer. Melamine fiber is a cost effective heat resistant fiber based on melamine chemistry, with a 400°F (200°C) continuous operating temperature. Melamine fibers are flame resistant, have outstanding heat/dimensional stability, and are self-extinguishing. EFT’s WF series of melamine fibers have a fiber length distribution tailored for use in wet-laid nonwovens. Typical fiber lengths are in the 1-12mm range, and they show excellent dispersion and formation in wet-laid processes.

Production Process of Melamine Fiber
The production process is proprietary. It is based on a unique melamine chemistry that results in a cross-linked, non-thermoplastic polymer of melamine units joined by methylene and dimethylene ether linkages. In the polymerization reaction, methylol derivatives of melamine react with each other to form a three-dimensional structure. This structure is the basis for the fiber's heat stability, solvent resistance, and flame resistance.

Applications of Melamine Fiber
  1. Mattresses, Home Furnishings / Nonwovens
  2. (Compliant with 16CFR1633)
  3. Specialty flame resistant papers
  4. Firefighting apparel
  5. Electrical papers
  6. Transmission / friction papers
  7. Filtration media
  8. Engineered materials / Short-fiber composites
  9. Adhesives / Fillers
  10. Tire sealants
  11. Truck / Rail brakes
Besides Melamine fiber has Potential use which are given below :
  • Fire Blocking Fabrics: Aircraft seating, fire blockers for upholstered furniture in high-risk occupancies (e.g., to meet California TB 133 requirements)
  • Protective Clothing: Firefighters' turnout gear, insulating thermal liners, knit hoods, molten metal splash apparel, heat resistant gloves.
  • Filter Media: High capacity, high efficiency, high temperature baghouse air filters.
