Polypropylene Tubes,made from homopolymer, block copolymer, and random copolymer polypropylene materials through extrusion and injection molding processes are crystalline polyolefin thermoplastic resin pipes, which can be abbreviated as PP tube.
The Core Features of Polypropylene tube
In polypropylene, each repeating unit carries a side group, which increases the rigidity of the molecular chain. As a result, the processed pipes exhibit excellent chemical resistance, high rigidity, good heat resistance, and outstanding weldability.
In addition, polypropylene can also be used as a type of transmission tubing. However, due to its large thermal expansion coefficient, poor flexibility, and tendency to become brittle at low temperatures, its applications are not as extensive as those of PE pipes.
Specifically, PP pipes have only moderate flexibility and low-temperature impact resistance, but their resistance to hot water and weldability make them more advantageous in applications such as hot and cold water supply, heating systems, and chemical pipelines.
The advantages of Polypropylene Tube
Polypropylene tubing has the advantages of chemical resistance, high temperature resistance, lightweight and non-toxic, Let's explore other structural advantages of this tube.
Strong chemical resistance:PP tube is a non-polar material with a relatively stable molecular chain structure and a high degree of crystallinity.
High temperature resistance:Polypropylene has a relatively high melting point and good thermal stability. Polypropylene tube can maintain their mechanical strength and shape within a certain temperature range.
Lightweight and High Strength:PP itself has a low density of about 0.9 g/cm³, and when it has a high degree of crystallinity, it gives polypropylene tube materials good rigidity and impact resistance.
Non toxic and odorless:PP tube can be used in industries such as food, drinking water, and pharmaceuticals, and meets safety standards because of its good Chemical inertness.
Smooth inner wall:Due to its smooth inner wall and low fluid resistance, pp tube can be used as a transmission conduit to reduce fluid friction and increase flow rate.
Affordable price:Compared with high-end plastics such as PTFE and PVDF, pp tube has a high cost performance ratio.
Structural Features Of Polypropylene Tube
At the microscopic structural level, PP tubes have high rigidity and a relatively high degree of molecular crystallinity; In terms of processing structure, they can be manufactured into various types such as solid-wall pipes, reinforced pipes, and multilayer composite pipes. Before use, it is necessary to understand the relevant parameters of PP materials in order to produce pipe structures that meet the intended application requirements.
