Adopting imported high-purity butyl rubber + Daelim polymer materials of the new formula, is a stable damping molecular substrate, the surface covered with a unique corrosion-resistant water-repellent coated aluminum foil, to ensure that the surface of the product is highly stable and not easy to oxidize. Its environmental standards meet the requirements of the European Union REACH directive, and it is environmentally friendly and odorless. Its remarkable damping characteristics can immediately change the resonance effect of the original substrate, and enhance the excellent wide-band damping and sound insulation properties! The temperature range of the product is -40ºC~160ºC.
Widely used in acoustic engineering sound insulation and vibration damping, railroad trains, automobiles, pipelines and other surface damping vibration damping.
High-density butylrubbercomposite soft aluminum foilcan effectively blocks the shock and propagation ofsound waves
Odorless and highly adhesive, with ultra-high tensileproperties. Strong anti-aging properties and it will not harden or melt in extremely cold or high temperatures
