Three-layer co-extruded super silent PP pipe production line
The nm. super silent PP drainpipe series with fire retardancy and high temperature resistance are new drainpipes for construction which are developed by absorbing the international advanced technology and adopting the nm. technology to satisfy the need of market. It adopts the technology of three-layer co-extrusion, which reduces greatly the noise from building drainpipes. The main material is environment-friendly which is the recyclable modified polypropylene resin with good impact resistance and protects the middle layer. The middle layer is made of special viscoelasticity inorganic material that absorbs sound. Through modification it has excellent functions of sound insulation, sound absorption and buffer vibration, and has significant performance of reducing the noise of frequency 2000-4000HZ. The inner layer has excellent heat resistance and chemical resistance, reaching the internationally advanced level in the field. The product is widely applied especially in draining water, discharging pollution and waste from high-rise communities, high-grade office buildings and apartments, hotels, restaurants, hospitals, schools, high-grade residential communities and industrial enterprises.
