Raw Material: Made primarily from PVC resin, with the addition of high-quality processing modifiers and impact-resistant toughening agents, processed through kneading and extrusion.

Product Features:

It has excellent insulation, flame retardant and impact resistance properties, as well as corrosion resistance. The inner wall of the double-walled corrugated pipe is smooth, while the outer wall is corrugated with a hollow structure, making the product lightweight with high ring stiffness. One end of the double-walled corrugated pipe features a flared mouth and socket connection, sealed with a rubber ring for easy installation and maintenance.

Specifications:

Chemical Resistance:

Stable against solvents such as gasoline, mineral oils, and most inorganic acids (except concentrated nitric acid), as well as many organic and inorganic salts.

　　4U-PVC Drainage Pipe Features:

　　U-PVC drainage pipes are primarily made from PVC resin, with the addition of appropriate stabilizers, lubricants, processing modifiers, and impact-modifying agents, processed through kneading and extrusion. Compared to ordinary PVC pipes, these have lower drainage noise, comparable to cast iron pipes. Furthermore, this product also possesses excellent physical and mechanical properties as well as chemical properties. It is lightweight, easy to install, significantly reducing construction time and cost. The internal helical pipe and hydrophilic inner wall PVC-U swirl silencer can be used in combination to reduce drainage noise, creating a quiet environment for users.

　　　Raw Material: This pipe is made from PVC resin, with appropriate stabilizers, lubricants, UV absorbers, processing modifiers, and impact-modifying agents added, processed through kneading and extrusion.

　　Physical Properties:

　　Drop Hammer Impact: No rupture

　　Vicat Softening Temperature: ≥79℃

　　Flat Test: No rupture

　　Break Elongation Rate: ≥10%

　　Longitudinal Recovery Rate: ≤9.0%

　　Application Areas: This product is widely used in building internal drainage pipes and rainwater downspouts, such as in mid- to high-rise residential buildings, upscale residential communities, hospitals, schools, hotels, etc.
