Environmentally friendly white high flame weather soundproofing membrane, measured retardant grade level to the German standard S4 grade polymer material properties even under outdoor weathering conditions highlights its strengths, other insulation materials can not match, it is recommended primarily for applications Special areas of rail transportation, machinery and equipment, in the field of high-end architectural applications will get perfect results. Perfect sound insulation properties, high flame resistance, especially in the outdoor reflect other EPDM rubber and other materials can not match advantage, to provide you with the perfect noise treatment program. Structural characteristics of a product, the country's first patented technology: production using multi-layer co-extrusion technology 2, the average 1mm thick materials have different densities of material 16 layer superposition of three products for the qualities of the composite polymer materials - White, our unique product color, because ordinary rubber materials and other products can not be achieved easily and white tones to distinguish between ordinary materials more soundproofing product performance characteristics: multi-layer composite structure design, giving the product a perfect sound insulation, 2 mm thick product average noise amount Rw ≥28dB, noise performance equivalent to 2.0 mm thick insulation materials imported TECSOUND damping performance, 100-630Hz low frequency region, the amount of noise up to 18-20 dB, is 1.5 times more than traditional products. More environmentally friendly: The product is a white, odorless, does not contain any toxic volatile compounds and hazardous waste recycling materials, dry fixed construction, avoiding construction adhesives formaldehyde contamination. (See environmental test report) more flame: environmentally friendly flame retardant, low smoke and toxic. High flame retardant test weathering products reach DIN5510-2: 2009-05 German rail vehicle fire test standard S4-level requirements. Compared with the market EPDM rubber insulation materials, fire-retardant effect was significantly more weather: Due to the use of polymer materials for the substrate, with a stable physical and chemical properties at room temperature can be acid, with a certain chemical resistance; of salt fairly stable, strong antioxidant capacity, its use is particularly prominent in the outdoor weather resistance, is common EPDM rubber insulation materials market can not be compared. More robust: tensile strength, elongation at break is much better than other traditional products. Can be arbitrarily cutting, bending, to facilitate construction. Also has excellent resistance to aging and waterproof. Compared with EPDM rubber insulation materials market, higher toughness, non-woven backing can not guarantee strength
