AKU®-LEN hollow bars made of PP-R up to 2,800 mm

Polypropylene possesses good rigidity, hardness, and strength, but low notched impact strength.
PP is not prone to stress cracking and is easy to weld.
However, embrittlement occurs at sub-zero temperatures.
The chemical and electrical properties are very good.
The continuous service temperature ranges from +5°C to approximately +100°C.

Polypropylene Random Copolymer (PP-R) is used where PE 100 is not suitable: at elevated operating temperatures, in aggressive chemical media, or when the component is to be hot-welded subsequently.

PP-R is lighter than PE 100, has higher stiffness at room temperature, and better resistance to a wide range of acids, alkalis, and organic compounds.

As a semi-finished product for machining, PP-R behaves somewhat more brittle than PE.

Outer diameter up to 2,800 mm, inner diameter up to 2,000 mm, pipe quality according to DIN EN ISO 15494. Tolerance ±2% on OD and ID. Standard delivery length 2,000 mm, custom cuts available.

Typical finished parts made from PP-R hollow bars: fittings, nozzles, fasteners, rollers, bobbins, vacuum containers, flanges, and components for the chemical industry.
