DONACOOL LIGHT (DCL) <Lightweight acoustic insulation>

DCL (DONA COOL LIGHT) is the nonflammable and ultra light insulation, having excellent restitution property against compression.
It is favorably used as acoustic insulation and thermal insulation of train cars, due to its excellent performance such as nonflammability and durability for vibration.

Applications

DONACOOL LIGHT is mainly used as a sound absorbing, heat insulating material for railroad vehicle, a material for inflammable cushions, and an acoustic isolation and heat insulating material with aluminum. In addition, DONACOOL LIGHT could used in various ways on ship, aircrafts, construction, roadside soundproof walls, flue gas ducts, plants, air-conditioning air filters, home electric appliances, and gas appliances.
