About Zotek N High temperature foams
It is a closed-cell crosslinked polyamide (nylon) foam for use in higher temperatures environments (200°C+) and is available in a range of densities. Compared to other foams ZOTEK® N has a significantly higher upper operating temperature limit. Thermal shrinkage at 205 deg °C can be less than 5% after 24 hours. This allows ZOTEK® N to be used in systems requiring high temperature processing such as composite cores or in-line paint systems.
ZOTEK® N is excellent thermal insulator and will act as heat shield - which can be further enhanced by the addition of an aluminium layer. ZOTEK® N is fully compliant with R.O.H.S & REACH requirements. It is lightweight (from 30kg/m density) and thus ZOTEK® N materials offer many weight saving and energy saving advantages.
Based on polyamide (nylon), ZOTEK® N has excellent general chemical resistance and is exceptionally resistant to hydrocarbons including fuels, oils, brake and power steering fluids, and antifreeze. Being a closed cell material, acoustic insulation is very good, with good noise, isolation and damping characteristics. It can be used in combination with other materials to optimise acoustic performance.
