Evonik has developed a highly transparent polyamide based on new monomers, which combines a relatively high heat deflection temperature with good mechanical properties and low water uptake. TROGAMID® HT is thus ideally suited for high-end ATEX applications in the higher temperature range.
In the past it has been difficult to develop certain industrial applications for transparent polyamides due to their inadequate high-temperature resistance. But with TROGAMID® HT Evonik is now launching a novel polymer with a glass transition temperature of 172°C, which is 30°C above that for comparable TROGAMID® products and therefore ensures high heat resistance.
Transparent polyamide with a host of advantages
A water uptake of lower than two percent confers outstanding dimensional stability; the very low density of 0.98 g/cm³ helps save weight. Excellent chemical resistance, high static and dynamic load capacity and wear resistance, high impact resistance, good weathering resistance, and scratch resistance open up many new applications in electrical and mechanical engineering and the automotive and sanitation industries.
TROGAMID® HT has already proven its worth as a high-performance material in advanced heating installations offering high quality and operational reliability. Components made from the high-transparency polymer from Evonik ensure optimal visual control by staff and have good dimensional stability even at high temperatures.
Material for composite applications
Due to its high softening temperature and excellent ductility, TROGAMID® HT has proven useful as an impact-resistance modifier for epoxy resins in composite applications in the aviation industry. The use of TROGAMID® HT powders in conventional matrices significantly improves fatigue behavior and crash resistance and reliably prevents typical defects such as microcracks.
TROGAMID® is a permanently transparent polyamide from Evonik that has proven its worth over many years in the sports, leisure, and automotive industries as well as in mechanical engineering, medical technology, and optics. Due to rising global demand for high-performance polymers, the specialty chemicals group is expanding TROGAMID® production in Marl Chemical Park. The expansion is expected to be complete in the first quarter of 2020, enabling Evonik to double its capacities for the transparent high-performance polymer.
