This material may also be needed in the construction of any cut, mainly used for building interior, muffler system, transport, refrigeration equipment, household appliances damping, sound absorption, noise reduction, the effect is very good. Glass wool felt with aluminum foil on the surface, but also has a strong thermal radiation, high temperature workshops, control room wall, and flat top compartment lining material. Bulk density: 10-72kg / m3 Thickness: 25-100mm Length: 3m-20m width: 1200mm Product Description density: 100-200kg / m3; Length: 1000-1200mm; width: 50mm, 80mm, 100mm; thickness: 28mm, 36mm, 40mm, 50mm, 75mm, 80mm, 100mm, (fiber vertical direction); special size, density and thickness can be customized according to customer requirements. Performance attributes: thermal conductivity (metal plate) 0.040W / mk acoustic / insulation: rock wool strips open architecture provides excellent absorption / noise performance. Fire: The product detected as non-flammable product with ASTM E-136 standard. Compressive strength: wool of the processing by the pressure plate made fibers belonging to erect in the pipeline process, so they can bear high loads. 5%: resistance to pressure> 25Kpa; 10%: resistance to pressure> 40Kpa. Moistureproofness: Yanmian waterproof, have a good ability to release water vapor pressure on the roof structure. Chemical and biological characteristics: rock wool strips PH value of 7 or was slightly alkaline, and in accordance with ASTM-C-795, JIS-A-9504 standard, which can not meet the normal mold, fungi, bacterial growth.
