Adhesives & Sealants For Sound Damping

Sika India Pvt Ltd offers Adhesives and Sealants for Sound Damping. The interior noise in a car is of significant importance in today's highly competitive world market. The company has innovative, high-performance products to reduce interior noise. SikaAcoustic System (SikaBaffle, and SikaDamp) is a heat reactive, pre-shape moulded, extruded and designed die cut part. The full acoustic system package (thermoplastic and elastomeric products) is optimised to reduce noise propagation through primary body structure from entering into the passenger compartment. The acoustic system is designed to seal the vehicle body cavities (SikaBaffle) and to damp (SikaDamp) the vibration of the body panels resulting in a driving and riding comfort. The SikaBaffle is a 3D thermoplastic (moulded) or elastomeric (extruded) part designed to seal a body cavity to provide significant increase in vehicle acoustic performance. SikaBaffle products are developed with various volumetric expansions to seal body cavities to meet OEMs design parameters. It is inserted in the assembly of body structure and expands during electro deposited (E-coat) oven to seal the body cavity. The high degree of expansion and the three-dimensional design of SikaBaffle products allow sealing of complex design cavities. SlkaDamp is a non-curing, lightweight, elastomeric constrained layer damper, SikaDamp, it is co-extruded with either aluminium foil or a glass cloth carrier for ease of application and production processes. Moulded parts: Sealing the body cavities contributes to the blocking of the exterior noise from entering into the vehicle compartment resulting in a much quieter ride. The moulded SikaBaffle parts can be robotically or manually inserted into vehicle cavities such as A, B, C, and D pillars.
