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 does not tend to form stress cracks and is easy to weld. However, embrittlement occurs at sub-zero temperatures. The chemical and electrical properties are very good.

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.

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