PP duct, also known as polypropylene duct, is a kind of semi crystalline material. It is harder than PE and has a higher melting point. Because homopolymer PP is very brittle at temperatures above 0 ° C, many commercial PP materials are random copolymers with 1-4% ethylene or clamp block copolymers with higher ethylene content.

PP air pipe is widely used in plastic engineering of PP waste gas treatment tower. Acid mist waste gas in the pipe of waste gas tower has certain corrosivity, so the pipe of waste gas treatment tower requires acid and alkali resistant PP air pipe.

Conventional size: Φ 90, Φ 110, Φ 160, Φ 200, Φ 250, Φ 315, Φ 355, Φ 400, Φ 450 (diameter), with a uniform length of 4m.
