Sound Absorbing Acrylic PE Foam Double Sided Tape 2mm 3mm for Battery Pack Sealing

This Sound Absorbing Acrylic PE Foam Double Sided Tape is built for the acoustic and sealing side of battery pack assembly. A compressible acoustic grade PE foam core is combined with a high tack acrylic adhesive on both faces, so the tape simultaneously decouples vibration, reduces structure borne noise and forms a continuous moisture barrier between the protection board, module frame and enclosure.

Available in 2mm and 3mm thickness in 5 metre rolls with custom slit width, it is aimed at PACK lines where the same component must solve bonding, noise reduction and sealing in one step, shortening the bill of materials and the number of assembly stations.

• Acoustic performance: the impedance matched closed cell foam layer interrupts vibration transfer between modules and enclosure, lowering structure borne noise in ESS cabinets and power stations.
• Shock and vibration damping: 2-3mm compressible core buffers road shock, drop impact and resonance during transport and field use.
• Sealing and moisture proof: closed cell structure does not absorb water, providing a gasket effect against dust and humidity ingress at board edges and cable outlets.
• High tack, high tensile: 20-28 N/25mm peel adhesion and more than 48 hours holding power at 1kg/25mm, resisting pull off under continuous vibration.
• Wide temperature and weather resistance: -30 C to 110 C long term, 140 C short term, with UV and ageing resistance for outdoor installations.
• Easy to process: available as roll, slit roll or die cut gasket, with a release liner that allows fast manual or automated placement.

• Noise and vibration control inside energy storage cabinets, container ESS and telecom backup power systems.
• Sealing of protection board compartments against dust and humidity in outdoor battery packs.
• Damping of module to shell contact points in e-bike, e-scooter and power tool packs.
• Acoustic gasket for portable power stations, home storage units and charging cabinets.
• Anti vibration mounting of fans, relays, contactors and busbar covers in the PACK.

• One tape, three jobs: bonding, damping and sealing come from a single SKU, reducing part count and assembly stations on your line.
• Real application testing: we benchmark adhesion and compression recovery on your actual substrate, not only on laboratory steel plates.
• Consistent foam structure: closed cell control during coating keeps acoustic and sealing performance stable from roll to roll.
• Custom conversion: slit rolls, kiss cut and full die cut gaskets produced in house, shortening your lead time for new pack designs.
