AKU®-LEN PP-R SOLID RODS or RODS in PP-R with diameters up to 1600 mm

Polypropylene has good rigidity, hardness and strength, but low notched impact strength.

PP-R is not prone to stress cracking and offers good weldability. However, embrittlement occurs at sub-zero temperatures. The chemical and electrical properties are excellent.
The continuous service temperature ranges from approx. -5°C to approx. +70°C.

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

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.

Solid rods are used for milling or turning – for example, for discs, bushings, turned parts, or as special custom geometries without suitable standard dimensions.
