Environmentally friendly soundproofing membrane, measured retardant grade level to the national standard B1 level; perfect sound insulation, wall insulation transform your old, the perfect choice for new light green walls and ceiling products, flame retardancy in full compliance! Claim. Structural characteristics of a product, the first domestic 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 composite polymer material qualities - White my company's unique product color, because ordinary rubber materials and other products can not be achieved easily and white tones differentiate product performance characteristics common materials more noise: multi-layer composite structure design, giving the product a perfect sound insulation, 2 mm thick product average amount of noise 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. Oxygen index up to 42%, vertical burning FV-0 level smoke density rating (SDR) = 26.25, general-purpose products, which amounts to building materials and products of combustion performance GB 8624-2006 standard B1 level requirements. (See the smoke density, oxygen index test report) 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 resistant acid, with a certain chemical resistance; for salts fairly stable, strong antioxidant capacity, particularly highlighting its use in outdoor weather resistance, is a common market EPDM rubber insulation materials can not match. 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, so our products can not guarantee non-woven backing strength
