Polypropylene Tubing, It is one of the three major types of Polyolefin Tubing.Commonly known as PP tubing, is a type of thermoplastic tubing mainly made from polypropylene resin.
We all know that thermoplastic pipe has the advantages of being heat-fusible for processing, easy to install, lightweight and high strength, aging-resistant, long service life, recyclable, and environmentally friendly.
For pneumatic systems with low pressure and temperature, polypropylene tubing can be used as the transmission medium.
Moreover,polypropylene transport Tubes also have excellent chemical resistance, high rigidity, good heat resistance, and outstanding weldability. Polypropylene pipe features a lightweight yet strong wall structure, capable of withstanding medium to low pressure, with an operating temperature typically between 0-95°C. Propylene transport tube is usually connected using hot-melt welding, hot-air welding, socket welding, or butt welding techniques, providing strong sealing and transmission performance.
Polypropylene tube is cost-effectiveness and corrosion resistance, widely used in chemical transportation, wastewater treatment, food processing, domestic hot and cold water systems, environmental protection equipment, industrial ventilation, and agricultural irrigation.
The Advantages of Polypropylene Tube
Polypropylene tubing has the advantages of chemical resistance, high temperature resistance, lightweight and non-toxic, Let's explore other advantages of pp tubing.
Strong chemical resistance:PP 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 pipes can maintain their mechanical strength and shape within a certain temperature range.
Lightweight and High Strength:Polypropylene (PP) itself has a low density of about 0.9 g/cm³, and when it has a high degree of crystallinity, it gives polypropylene hose materials good rigidity and impact resistance.
Non toxic and odorless:Polypropylene hose 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, polypropylene pipe 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 tubing has a high cost performance ratio.
