Polypropylene (PP) is a material with high impact resistance and a high operating temperature range. In addition, the material is lightweight and has a high chemical resistance. Add to that the excellent mechanical properties and Polypropylene PP is one of the most versatile plastics around.
Polypropylene is not only extremely suitable for technical applications and construction, but also for advertising applications and packaging of different sizes. Polypropylene is also widely used in the chemical industry.
Polypropylene is widely abbreviated as just PP.

Welding Polypropylene
Polypropylene can be easily welded including infrared welding. In addition, PP-H and PP-C are easy to wire weld. The air volume (L/min) is 45-55, the welding air Temp. 300-340ºC (measured approx. 5mm in the welding nozzle) the welding speed cm/min is 25-35. PP (PP-H, PP-C) is also good for extrusion welding. The welding parameters here are: air volume (L/min) 300, welding air Temp. 210-240ºC and the welding mass Temp. 250-300ºC.
PP-R is easy to electroweld and PP-R, PP-H are also very suitable for socket welding/mirror welding.
How to identify Polypropylene (PP)
Colour is not always an indicator, but PP can often be identified by the grey/beige colour, RAL7032. When you ignight PP, you can identify it by the blue flame, yellow top and light gray smoke.
The specific gravity is less than 1, which makes PP float.
The technical properties of Polypropylene (PP)
Polypropylene PP is very similar to PE, but has a higher temperature resistance (up to 100 degrees) and is also much tougher. For example, Polypropylene-PP sheet can hinge endlessly, without breaking.
Polypropylene PP is easy to machine and weld and is suitable for galvanising baths, storage tanks and piping.
