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.

AKROLOY® PARA GF 35 FR orange (8039)
Thermal runaway is an uncontrolled chain reaction within batteries, which leads to self-destruction of the cells caused by internal heat generation. This leads to a rapid rise in temperature (possibly exceeding 1000 °C).
AKROLOY® PARA GF 35 FR orange (8039) withstands exposure to a 500 W flame for over 10 minutes at a component thickness of just 2 mm. This leads to temperatures of up to 1200 °C. The temperature rise the back is moderate, at a maximum of 115 °C.
It also passes 6 cycles in the Torch and Grit Test (TaG) with a plate thickness of just 3 mm. In this test, the sample is alternately exposed to a 500 W flame for 15 seconds, followed by 5 seconds of high-velocity particle impact. This reflects one cycle. The material performs significantly better in this test than other established materials on the market, which is why there is no need to incorporate additional materials such as organosheets or thermal barrier sheets. This leads to a reduction of process complexity and costs.

What advantages does PARA FR offer for thermal runaway requirements compared to other flame-retardant compounds?
:format(avif))
PARA FR exhibits the lowest peak heat release rate combined with the lowest smoke generation - excellent properties for a thermal insulation material inside the battery.

AKROMID® B28 GF 30 9 FR orange (8645)
AKROMID® B28 GF 30 9 FR orange (8645), a flame-retardant PA6 compound with 30% glass fibers, colored orange, similar to RAL 2003, was specially developed for high-voltage components (HV connectors, busbars, or housings). The flame-retardant system is based on the latest technology and is free of red phosphorus, halogens, antimony trioxide, zinc borate, and PFAS. It therefore complies with the latest regulatory requirements and offers significant processing advantages such as reduced corrosion susceptibility and reduced deposit formation.
This grade is UL listed with a UL94 V0 classification at 1.6 mm. Due to its excellent flowability, it is characterized by easy processing and good surface properties. The material possesses excellent long-term thermal stability and outstanding mechanical properties. The product is available with a glass fiber content of 25% to 35%, in natural and colored in RAL 2003 or black.
The products are also available based on biomass-balanced raw materials: AKROMID® NEXT B28 GF 30 9 FR black (8342BMBCI).

AKROTEK® PK-VM GF 30 FR orange (8537)
Our flame-retardant AKROTEK® PK-VM GF 30 FR orange (8537) offers high ductility despite its flame-retardant treatment, providing advantages such as high chemical and hydrolytic resistance, robust electrical properties, and dimensional stability. It is a process-optimized grade, giving injection molders a wider processing window and therefore greater processing flexibility. AKROTEK® PK-VM GF 30 FR meets the highest flammability requirements and is UL Listed V0 in all colors starting at 0.8 mm, including RTI listing.
The product was developed for injection molding but can also be processed using 3D printing and pellet extrusion for large-scale additive manufacturing (see video).

FLAME RETARDANT POLYESTER WITH SUPERIOR DUCTILITY
PRECITE® P3 GF 25 9 FR natural (8212)
Our PRECTITE® P3 GF 25 9 FR natural (8212) was specially developed to meet the highest demands for dimensional stability and ductility. Like all our materials, the product is free of halogens, antimony trioxide, and PFAS and complies with the latest regulatory requirements. With an elongation at break of >2.5%, it provides the high ductility often required for components while still achieving a UL94 V0 classification at 1.6 mm component thickness. The product is also available in black and as a GF 30 version.
