ISOLITE GMBH (Germany) has developed XP Filling, a light and flexible material that makes a comprehensive solution for insulations of cold-end exhaust systems such as middle silencer and rear silencer. First insulation fibre product from the company, XP Filling drwas from the company's experience in the commercial vehicle, automotive and aviation fields in hot-end technologies. ISOLITE XP Filling provides its customers with an easy-to-mount, cost-effective insulation solution. Said Matthias Kroll, Managing Director, ISOLITE Group, "ISOLITE XP Filling uses the expanding characteristics of our innovative XP technology in a whole new field of application." Silencers normally feature a layer-like structure. Insulation mats or small plastic bags were often used up to now. However, these do not meet the demands of complex constructions. In particular interspaces or hollows as well as narrow angles or edges create a high degree of difficulty. Also, assembly operations often cause a number of challenges such as protruding fibre filaments during the welding process. With the newly developed insulating fibre ISOLITE XP Filling, ISOLITE is providing a solution for the requirements in the field of cold-end insulation.
