Murylon® HT
- Chemical Family
- Polyamides
Murylon® HT, use of this highly temperature resistant polyamide enables reliable operation up to a constant service temperature of +155ºC. The material retains its rigidity and creep strength over the entire temperature range far better than other Murylon® types. Thanks to its increased resistance against oxidative degradation, it is usually used in applications at above +80ºC. Production based on PA46.
