Colour-stable, tailor-made polyamide for electric cars 

11.05.2022/XNUMX/XNUMX | With the Ultramid A3U44G6 DC OR (PA66 - GF30 FR) BASF expands the portfolio of flame-retardant technical Plastics in the manufacture of electric vehicles. The high technical requirements in electromobility require innovative solutions based on PA66. With the tried and tested Ultradur (PBT), the color stability can be largely guaranteed, especially in orange (RAL 2003), which is in high demand throughout the industry. Conventional polyamides, on the other hand, tend to have strong color variations. These polyamides also show yellowing on heat aging.

“High-voltage components are usually exposed to significant temperature fluctuations. With conventional polyamide, this leads to severe discoloration. Our newly developed Ultramid A3U44G6 DC OR polyamide closes the gap in terms of color stability and mechanical strength," explains Tina Weller, Product Development BASF. For the first time, the new polyamide meets all the criteria of the color stability and resistance to heat aging. It allows long-lasting color coding, which is safety-relevant in the sensitive area of ​​high voltages. The color stability was confirmed in tests after 1000 hours at temperatures of up to 130 °C.

In addition to color consistency, the Ultramid A3U44G6 DC OR with a CTI 600 offers a high electrical insulation. The use of tailor-made pigments while at the same time avoiding flame retardants containing halides counteracts electrocorrosion. Until now, it was difficult to contain it, especially when it was damp. "During development, we attached particular importance to avoiding halides such as iodide and bromide, thus paving the way for a long-lasting product without contact corrosion," explains Michael Roth, Product Development BASF.

At a very low level total halide content of less than 50 ppm, the PA66 achieves fire protection class UL94 V0 at 0,4 mm. In addition, the polyamide is equipped with a special organic heat stabilization package.

Low-corrosion polyamides with very long tool life

Flow improver now for the full range of polyamides

25.09.2019/1810/XNUMX | "Brüggolen TP-PXNUMX" from Brüggemann allows for the first time a significant improvement of the often critical Flow properties of polyphthalamides (PPA, such as PA6T, PA6T/6I, PA6T/6.6 etc.) while maintaining the mechanical property profile. Compounders and injection molders can thus significantly expand the processing window and combine high cost efficiency with application-specific optimization.

For example, with Bruggolen TP-P1810 the possibility of safely producing compounds with a very high fiber content (e.g. 60%) and processing them well. Together with Brüggolen TP-P1507 for aliphatic polyamides (such as PA6, PA6.6, PA12 etc.), the plastics specialist now offers flow improvers for the entire polyamide spectrum.

Manufacturers and processors accordingly Compounds benefit in particular from significantly shorter cycle times. In addition, both flow improvers facilitate the manufacture of large or complex parts with long flow paths and/or thin walls. With the thermal stabilizers for polyamides presented for the first time and the extensive range of existing types, solutions are available for all stabilization tasks.

Polyamide sets standards for the fuel cell

12.03.2019/XNUMX/XNUMX | In close cooperation with Joma Polytec and the Daimler AG subsidiary Mercedes Benz Fuel Cell has succeeded in making some components of the fuel cell system from the technical plastic "Ultramid" from BASF to manufacture. It is used as standard in the new "Mercedes GLC F-Cell", which is equipped with a combination of fuel cell and rechargeable Lithium Ion Battery Is provided.

The polyamide Ultramid offers good thermal and chemical resistance, dynamic strength, toughness and good long-term use properties in the Mercedes GLC F-Cell.

Together with Joma-Polytec and the Daimler AG subsidiary Mercedes-Benz Fuel Cell, a development project brought to life in order to optimally meet the extensive requirements: temperature resistance, media resistance, longevity. Due to the unique material basis and intensive material analyzes with regard to chemical and mechanical resistance, the companies involved selected the tailor-made Ultramid grades A3WG10 CR and A3EG7 EQ.

With Ultramid A3EG7 EQ, a material is available that is ideally suited for sensitive applications in the electronics industry due to the special purity requirements. In the case of the media distribution plate and the water separator unit, which are exposed to a wide variety of media with the cooling water, air and hydrogen channels, this Ultramid proves its very good resistance and at the same time meets all the requirements for the purity of the material.

Polyamide for the charge-air duct in the combustion engine

12.10.2016 | BASF reacts to this Further development of engine concepts with a coordinated portfolio of polyamide PA6 and PA66 types that meet the increased demands on the materials used, their mechanical properties and temperature resistance. Depending on the base polymer and stabilization system, the materials are resistant to heat aging up to 220°C and have excellent bursting pressure and weld seam strength.

In this way, the developer can choose the right material for different components of the charge air path to provide. Selected types are based on global specifications: they are supplied worldwide from local production, with uniform material properties and consistently high quality.

The portfolio of polyamides includes PA6, PA66 and PA66/6 types with a glass fiber content between 30 and 50%. "Ultramid B3WG6 GPX", a PA6 with 30% glass fibers, was newly added to the portfolio. It is temperature-resistant up to 180 °C and briefly up to 200 °C and is suitable for multi-part charge air distributors due to its bursting pressure and weld seam strength. The upper end of the temperature spectrum is covered by "Ultramid Endure", a specialty polyamide that enables continuous service temperatures of 220 °C and peaks of up to 240 °C.

The ones for that suitable for injection mouldingThe types Endure D3G7 with 35% and D3G10 with 50% glass fiber reinforcement have proven themselves in charge air distributors of highly charged diesel engines as well as in resonators and sensors. Well-known OEMs use the Endure D5G3 BM with 15% glass fibers, which is suitable for suction blow molding, in charge air tubes. For the range between 180 °C and 210 °C there are PA66 products with improved heat stabilization. These include Ultramid A3W2G6 to G10 (from 30 to 50% glass fiber reinforcement) for temperatures up to 190 °C, e.g. B. in intercooler end caps and the new Ultramid A3W3G7 for temperatures up to 210 °C.

Cast nylon Lauramid receives new DIN designation

24.05.2012/XNUMX/XNUMX | The high-tech art stuff Lauramide from Handtmann Elteka receives a new material abbreviation. The cast polyamide previously designated “PA 12 G” according to DIN is now called “PA 15860 C” according to the current EU DIN EN 12. “C” stands for the English term for Icing, namely “cast”.

The high-performance plastic polyamide Lauramid shows its advantages over simpler ones, such as those of injection-moulded plastics, among other things through its special manufacturing method out of. Lauramid is poured into molds without pressure and polymerizes there. This results in low-stress and therefore extremely dimensionally stable semi-finished and finished parts. Other advantages of casting: Metal parts such as hubs can be permanently cast into Lauramid components during manufacture and components can be manufactured with near-net shapes. Both save further processing costs.
