The k fluẍ® product in the Lydall fluẍ thermal and acoustical shields product family is designed for high temperature applications where superior and more thermally efficient materials are required. Through the combination of low emissivity metals and a high temperature low thermal conductivity insulating media, k fluẍ provides marked thermal isolation for sensitive components even when exhaust temperatures exceed 900 °C.
