Based on the newly developed Polystone® G CubX®, Röchling is consistently pursuing its strategy of simplifying the design of its rectangular tanks in as many applications as possible. In 2018, Röchling developed Polystone® CubX®, a completely new tank construction sheet specifically for the design of rectangular tanks. Its special feature is its design: Polystone® CubX® is cross ribbed twin-wall sheet with an internal cubiform cell structure. Its interior consists of a homogeneous, orthogonal grid pattern welded on the outside to two sheets, which form the surface of the sheet.
This results in a construction sheet having a very high longitudinal and transverse rigidity. In contrast to conventional solid plastic sheets, rectangular tanks made of Polystone® CubX® require no or significantly less steel reinforcement, depending on their size. This makes for a faster construction and simpler design.
Because of the high demand, Röchling has developed Polystone® G CubX®, the first version having cover sheets made of Polystone® G (PE100 RC). In 2019, the company already developed the flame-retardant Polystone® PPs CubX® variant and the UV-resistant variant Polystone® CubX® PG-UV stabilized white – each having cover sheets made of a polypropylene homopolymer (PP-H).
Polystone® G CubX® with the PE100 RC cover sheets is specifically designed for applications in which connecting pipes, equipment or entire system components are made of PE and PE is the required tank material. The material is also suitable for storage and process tanks, in which chemical media are stored or used for which the resistance of PE to chemicals makes it the only suitable construction material.
Röchling works closely with tank manufacturers to develop Polystone® CubX® further. Matthias Klein, Product Management CubX®, explains: "We had detailed discussions with many interested parties about the properties and were often asked for a polyethylene variant. We directly chose a cover made of PE100 RC. In addition to its high UV resistance, it offers higher strength and better resistance to stress cracking than a standard PE-HD. We are pleased that based on this new development we are able to offer our customers another option for further simplifying the design of their tanks".

Based on this development, Röchling is expanding its competence in chemical tank and plant construction even further. Röchling plastics have been used for decades in chemical tank and plant construction all over the world. Röchling offers a complete system consisting of sheets, U-profiles and tubes in addition to different welding rods and the tried and tested tank calculation program RITA®. Furthermore, Röchling has a comprehensive database and many years of experience in chemical resistance and the successful use of plastics.
