Invention Reference Number
This innovation introduces a halogen-free, biobased, environmentally friendly flame retardant designed for building materials. It offers a sustainable alternative to traditional halogenated flame retardants, which are petroleum-based and often leach out toxins. Designed to meet stringent fire safety standards, this solution substantially reduces health and environmental risks supporting the construction industry’s shift towards safer, more sustainable materials.
Description
The flame retardant is synthesized from renewable, bio-based feedstocks and operates through a halogen-free dual-action mechanism. In the condensed phase, the material forms a protective char layer when exposed to fire, slowing heat penetration and flame propagation. In the gas phase, it releases non-toxic gases that reduce the efficiency of combustion, further preventing flame spread. This dual mechanism not only enhances fire retardancy but also minimizes toxic emissions during fires, helping to meet regulatory demands in construction.
Benefits
- Reduced toxicity: Free from halogens, reducing harmful chemical release during fire exposure.
- No leaching: Non-volatile composition prevents leaching or off-gassing, ensuring durability.
- Cost competitive: Uses bio-based and readily accessible resources, aiming for cost parity with traditional petroleum-based alternatives.
- Sustainable: Lower carbon footprint than traditional flame retardants by using renewable, bio-based resources.
- Safe: Engineered to meet stringent fire safety standards.
Applications and Industries
- Building materials: Suited for use in thermal insulation and exterior cladding.
- Textiles and plastics: Provides flame retardancy across diverse materials.
- Passive fire protection: Ideal as an additive in intumescent coatings, primers, fillers, and fire-stopping products.
