SikaBaffle® are 3D, heat-reactive thermoplastic (molded or extruded) or elastomeric (extruded) parts designed to seal a body cavity. SikaBaffle® products have been developed with a variety of volumetric expansion properties to ensure even complex body cavities can be sealed to meet OEM design parameters. By altering the design and thickness of the parts, acoustic properties can be tailored to meet even the most demanding requirements. Once cured, SikaBaffle® products offer excellent adhesion to oily and e-coated body panels, including all of the main substrates used in the automotive industry — cold rolled, galvanized (hot dipped and electroplated) and galvanneal steel, as well as automotive grades of aluminum. They also maintain their adhesion properties through a range of aging and weathering test conditions.
