Sustainable Flame Retardant Compounds
For applications requiring flame retardancy, recycled materials are often unsuitable as a sustainable raw material source because impurities or fluctuations in the source material prevent reliable flame retardancy. Our AKROMID® NEXT FR product group is based on (partially) biobased, biomass-balanced, or chemically recycled content and contributes to the reduction of fossil raw materials and/or CO2 savings while maintaining consistent raw material quality and properties. Further information on our sustainable polyamide solutions can be found here: AKROMID® NEXT - for innovative and sustainable alternatives (akro-plastic.com)
Sustainable, flame-retardant polyamide compounds as drop-in
Almost all AKROMID® FR compounds can be replaced with a biomass-balanced solution. This consists of biomass-balanced polyamide and biomass-balanced flame retardant, which can significantly reduce the product's carbon footprint. Requalification by the user is not necessary. One example is our AKROMID® NEXT B28 GF 30 9 FR black (8342BMBCI), which is ISCC+ certified. It has an allocation factor of 94%, meaning 94% of the organic content is replaced by sustainable, biomass-balanced raw materials. It is a drop-in solution for existing PA6 GF 30 FR(40) compounds, with a V0 classification for component thicknesses of 1.6 mm and above. For the E&E market, we recommend our AKROMID® NEXT C3 GF 25 1 FR natural (7208BMBCI), which has a UL94 V0 rating from 0.8 mm thickness and excellent RTI values. The allocation factor for this product is 98%.
Polyamide 5.6 GF FR - bio-based alternative to PA6.6 GF FR
Polyamide 5.6 contains up to 35% bio-based carbon and is an HMD-free (hexamethylenediamine) alternative to PA 6.6 with comparable properties and shrinkage behavior. Our portfolio includes AKROMID® NEXT 5.6 3 GF 35 9 FR natural (8401), which achieves a UL94 V0 classification at 1.6 mm and is suitable for components with high strength requirements. AKROMID® NEXT 5.6 3 GF 30 FR natural (8403), which offers a V0 classification up to 0.8 mm component thickness and was therefore specifically developed for the E&E market.
Low Warpage PA6 with glass bead/glass fiber mixture
Our AKROMID® B28 GM 15/15 FR black (8750) is a blend of 15% glass fiber and 15% glass beads, thus offering a 15% recycled content (PIR). The product's good flowability, excellent surface properties, and low warpage make it suitable for housing applications in the E&E industry. It has a UL Yellow Card with a V0 classification for component thicknesses of 0.8 mm and above. The product is also available with a biomass balance as AKROMID® NEXT B28 GM 15/15 FR black (8750BMBCI).
AKROMID® B28 GM 5/25 FR black (7492) contains 25% glass beads and 5% glass fibers and has a 25% recycled content (PIR). It offers a V0 classification for component thicknesses of 1.6 mm and above, and nearly isotropic shrinkage behavior. Both products are conceivable alternatives to PA6 GF 20 FR(30) or PA6 GF 30 FR(30) compounds when melamine cyanurate-free properties are desired. Like all our FR compounds, the products are free of halogen-containing flame retardants, PFAS, and red phosphorus.
