Product Description

Polypropylene (PP) ultra-quiet drainage pipe is a new type of building drainage pipe fittings developed by advanced silencing technology, this ultra-quiet drainage pipe is produced by three-layer co-extrusion process, the inner and outer layer is made of polypropylene material, the middle layer is made of specially modified polypropylene material with lake viscoelastic, the special intermediate layer material has excellent absorption and vibration mitigation function, therefore, This drainage pipe has the chemical corrosion resistance, heat resistance and impact resistance of general plastic pipes, and the biggest characteristic is that the silence effect is good, which is 20dB lower than ordinary plastic pipes and 10B lower than cast iron pipes. Due to the use of polypropylene material, the material has excellent heat resistance, can work at a high temperature of 90℃ for a long time, and the service life is up to 50 years
