Grinova H combines high mechanical performance with cost-effective component production. This high-performance polyamide opens up new opportunities to replace metal, standard PPA, and high-performance polymers such as PPS and PEEK. Thinner wall sections and lower weight reduce material consumption, while shorter cycle times and less post-processing lower total costs. Grinova H therefore gives designers and processors new opportunities to manufacture high-performance components more economically.

Exceptional stiffness at high temperatures and best-in-class creep resistance among PPAs (polyphthalamides) make Grinova H particularly attractive for demanding applications. In key properties, this high-performance polyamide outperforms established high-performance polymers such as PPS (polyphenylene sulfide) and PEEK (polyether ether ketone), creating additional potential for metal replacement and functional integration. Specific applications demonstrate just how significant these benefits can be.
For components exposed to high temperatures and continuous loads, creep resistance determines how much a component deforms over time. Grinova H delivers exceptionally high performance in this respect.
One example is a transmission cover currently made from standard PPA. At 140 °C, the component is exposed to an internal pressure of 20 bar from the transmission oil and may deform by no more than 0.3 mm. The high stiffness of Grinova H makes it possible to reduce wall thicknesses, thereby saving material and weight. At the same time, shorter production cycles can further reduce total costs.
The potential of Grinova H is also evident in the sliding shoe of a shift fork for automatic transmissions. Grinova H successfully replaced PEEK-CF40 with 40% carbon fiber reinforcement. The required temperature and wear resistance at 110 °C over 400,000 cycles were successfully demonstrated. At the same time, Grinova H is easier to process and enables cost savings of more than 60% compared with PEEK.
Grinova H also offers an impressive property profile for demanding busbar applications in electric vehicles. Busbars are electrical conductors that transfer electrical energy from the battery to components such as the inverter or motor controller. Their insulation must remain safe even at high temperatures and under significant temperature fluctuations.
Grinova H provides excellent electrical insulation, high thermal resistance, and mechanical robustness. Its comparative tracking index (CTI), which indicates resistance to the formation of unwanted conductive paths along the material surface, as well as its resistance to temperature cycling, were successfully demonstrated in thermal shock tests from –40 to +125 °C. In direct comparison, PPS did not meet the electrical and thermal shock requirements.
