Flame-retardant without PFAS
:format(avif))
AKRO-PLASTIC GmbH supports the E&E, household appliance, e-mobility, and public transportation markets with a customized portfolio of flame-retardant products, all free of red phosphorus, halogen-containing flame retardants, antimony trioxide, zinc borate, and PFAS-containing anti-drip agents. We continually monitor the latest technologies and regulatory changes to offer you innovative and future-proof solutions.
We will find the right product for you from our flame-retardant portfolio:
AKROMID® FR: PA6, PA66, PA66/PA6-Blend
AKROMID® T91 FR: PA9T
AKROTEK® FR: PK - Polyketone
AKROLOY® FR: PARA - Polyarylamide
PRECITE® FR: PBT
Flame-retardant materials are often used in electronic devices. It is therefore necessary to pay particular attention to electro-chemical corrosion. All flame-retardant materials from AKRO-PLASTIC GmbH are halogen-free. This applies not only to the flame retardants, but also to the heat stabilizers used, thus allowing solutions that prevent corrosion on micro-processors as a result of unfavourable stabilization systems. In addition, better electrical properties can be achieved compared to halogenated flame retardant systems, which is reflected in higher CTI values and makes it possible to use them in the field of high-voltage components.
Electro-neutral materials with a specified halogen content are particularly in demand in the field of battery management. AKRO-PLASTIC GmbH offers special EN compounds (EN = electro-neutral) for this purpose, which guarantee halogen contents <10 ppm (for bromine + iodine) thanks to technical formulation and production measures. AKROMID® B28 GF 35 FR EN black (7484) is therefore the perfect solution for battery housings with a component thickness >1.6 mm. If a guaranteed EN quality is not explicitly required, we refer to the AKROMID® B28 GF 35 9 FR black (8189).

Highest mechanical properties
For applications with high demands on mechanical properties, FR compounds containing 25-35% glass fibers are preferred. The presence of a high proportion of flame retardant, which is necessary for a V0 classification at low component thicknesses, negatively impacts the mechanical properties of the compound. Thanks to our many years of experience with highly reinforced materials and our gentle handling of the glass fibers during processing, we are able to produce flame-retardant materials with high mechanical properties.

ICX®-Technology
The ICX® Technology (Innovative Compounding and Extrusion Technology), developed jointly with our mechanical engineering and sister company FEDDEM GmbH & Co. KG, contributes to ensuring consistently high quality, regardless of location. This technology includes identical machine and peripheral technology, as well as standardized processes at all production sites.

A sustainable solution for your application?
AKROLOY® NEXT PARA GF 35 1 FR black (9023BMBCI) is based on biomass-balanced flame retardants and fillers. The product’s properties remain unchanged, and no costly re-qualifications are necessary. This means the CO₂ value can be reduced as needed without the need for testing. This sentence will be revised. I will submit it as soon as it has been reviewed.
Why is AKROLOY PARA GF 35 1 FR orange (8039) the perfect material for thermal runaway applications in e-mobility?

AKROMID® T9 - flame retardant, low corrosion PPA
AKROMID® T91 GF 30 FR black (8184) is ideal for thin-walled electrical and electronic components because it offers exceptionally high flowability, low moisture absorption, and excellent heat resistance. This compound is UL-certified V0 starting at 0.25 mm, prevents blistering during the reflow soldering process, and shows very low corrosivity, which significantly reduces wear on injection molding machines. This is a clear advantage over many flame-retardant high-temperature polyamides.

Are you looking for a safe, color-stable solution for high-voltage connectors in e-mobility?
AKROMID® T91 GF 30 FR orange (8104) - PA9T - A Newcomer for High-Voltage Applications
For high-voltage connectors in e-mobility, AKROMID® T91 GF 30 FR orange (8104) offers a particularly safe and reliable solution. The material stands out for its high stiffness and strength, even when conditioned and is available in orange similar to RAL 2003. It remains color-stable even under thermal stress and can be precisely marked with a UV laser thanks to its excellent laser-markability. Its high flowability allows for thin-walled, visually high-quality components, while its low water absorption ensures excellent electrical properties up to 150°C, both in the conditioned state and after heat aging.
Compared to other halogen-free, flame-retardant PPAs, the material exhibits a barely measurable corrosive effect, which significantly reduces wear on injection molding machines and increases process reliability.
The combination of stability, durability, and reliable performance makes it the preferred material for demanding high-voltage applications.
