CTK Practic is a basic sound-dampening material with a low resonant frequency, good adhesion to the surface and very high flexibility. It is based on butyl composite and polymers. The material is produced in the form of sheets with an adhesive layer on one side. Outside there is a layer of embossed aluminum foil with a thickness of 60 microns (0.06 mm), which provides less effort and a great degree of flexibility during the application process working with irregular shapes, reinforcement of the damping material, mechanical protection and further improvement of material acoustic properties. CTK Practic has an universal thickness of 2 mm and it is designed for basic absorption of the vibration, sound and resonance of all essential car body components such as roof, hood, dashboard, doors, door panels, floor, trunk lid, etc. The materials of the CTK Practic series are a good combination of quality, good damping characteristics and an attractive price. For this reason, these materials are widely used in different areas.
