Flame-retardant Compounds
Flame-retardant Compounds
A sustainable future needs safe innovations
Due to increasing safety requirements and new future-proof technologies in the fields of E & E, E-Mobility and Public Transportation, flame retardant materials gain more and more importance. AKRO-PLASTIC GmbH supports the markets with a customized portfolio of flame retardant products with the latest technologies.
Flame retardant grades are often used in electronic equipment. Therefore, it helps if special attention is paid to electro-chemical corrosion. All flame retardant materials of AKRO-PLASTIC GmbH are completely free of halogen containing heat stabilizers or flame retardants and red phosphorus. This results in high CTIs for each grade. It allows solutions that avoid corrosion on micro-processors due to unfavorable heat stabilizers.
Due to technical formulation and production measures, electrical neutrality with regard to halogen compounds <10 ppm for bromine + iodine can be guaranteed for special EN grades, e.g. AKROMID® B28 GF 35 FR EN black (7484). If a guaranteed EN quality is not explicitly required, please refer to AKROMID® B28 GF 35 9 FR black (8189).

Flowability
Unreinforced flame retardant grades are the best solution for components where thin parts take on an important task of the application, for example film hinges. AKROMID® C3 1 FR orange (7470) is optimized for excellent flow, ensuring good material flow through these thin areas during production. When cost optimization is an essential part of the project, AKROMID® B3 1 FR orange (7698) is a good solution.
Numerous reinforced and flame-retardant products in the AKROMID® range based on PA6, PA 6.6 or PA blends are characterized by easy processability and good surface properties. Combined with good long-term heat stability and outstanding mechanical properties, AKROMID® B28 GF 25 9 FR natural (8066) and its UL-listed V0 classification at 1.6 mm is suitable for applications in e-mobility.

Impact strength
For applications with high demands on mechanical properties glass fiber reinforced flame retardant polyamides are favorised, mostly with 25 or 30 % of glass fibers. Unfortunately flame retardants lower the mechanical properties of the compound.
With our long experience in highly reinforced materials and our gentle treatment of the glass fibers during processing we are able to produce flame retardant materials with higher mechanical properties than our competition.

Specialities
For high-end parts which need very high mechanical properties and outstanding dimensional stability AKRO-PLASTIC offers different flame-retardant grades based on special polyamide raw materials.
High mechanical properties over a wide temperature range, low moisture uptake and excellent surface – these requirements are perfectly matched by AKROLOY® PARA GF 35 FR (7496). With a tensile modulus of 14500 MPa and a tensile strength of 200 MPa this material offers more freedom to design mechanically stressed, flame retardant parts.
AKROMID® T9 GF 15 FR LA black (8197) is suitable for high-temperature applications in the automotive sector or in mechanical engineering, which also require high rigidity and strength at temperatures above 120°C. AKROMID® T9 is based on a PA9T homopolymer and has low moisture absorption and good media resistance. The above-mentioned grade achieves fire classification UL94 V0 from 0.8 mm, CTI 600V and is laser-markable.

Applications in the high-voltage sector
The flame-retardant and heat-stabilized compound AKROMID® C3 GF 25 1 FR, specially developed for components in the high-voltage sector (HV connectors, busbars or housings), is listed to UL94 in all colours, including RTI listing. AKROMID® C3 GF 25 1 FR orange (7854) similar to RAL 2003 has good color stability when exposed to heat.

Polyketone with 30% glass fibres and halogen free flame retardant similar to RAL 2003
AKROTEK® PK-VM GF 30 FR orange (8537) is a Polyketone with 30% glass-fibers and flame retardant free of halogens similar to RAL 2003. This grade meets the highest requirements for flammability such as UL94 V0 at 0,8 and electrical properties such as CTI of 600 V. This grade is optimized to the requirements of larger processing windows. Engineered for injection moulding this material can also be 3D-printed using pellet extrusion in large scale additive manufacturing.
