The main objective was to protect a high-temperature area within the car body from radiant heat. In the process, an existing product had to be adapted to changing requirements in order, among other things, to protect components with a lower temperature resistance from heat while simultaneously keeping temperature loss low.
In addition to a surface with strong media resistance that can withstand high temperatures, it was also necessary to prevent possible delamination of the aluminium foil in the temperature range up to 350°C. Furthermore, it should be possible to easily dismantle the textile protective cover by means of snap fasteners, and airborne fibre during fabrication and assembly should be kept to a minimum in the process.

Products do not always have to be completely redeveloped to meet the ever-increasing demands of the automotive industry. This is demonstrated by the example of the fabric for the textile heat shield from REX. This easily dismantled high-performance product was explicitly adapted to the new requirements and needs and, thanks to a complex and certified test procedure, meets all the necessary standards to be used not only in the automotive sector but also for series production and assembly. This includes high media resistance to substances such as oil and petrol and extreme resilience to heat up to 350 °C, with radiation sources of up to 1000 °C – customised and mass-produced by REX.
