Response to market feedback: Polystone® PPs CubX® – a flame-retardant version of the innovative tank construction sheet
Haren/Germany – Röchling Engineering Plastics SE & Co. KG, Haren/Germany, now offers Polystone® PPs CubX®, a flame-retardant version of Polystone® P CubX®, a tank construction sheet developed in 2018. Röchling is thus responding to the wishes of many customers for a version designed for sensitive areas of application. Polystone® PPs CubX® is especially suited for areas with strict fire safety requirements.
In 2018 Röchling developed Polystone® P CubX®, a completely new tank construction sheet specially designed for the construction of rectangular tanks. The design is what makes it unique: Polystone® P CubX® is a 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 finished sheet. The result is an innovative construction sheet with very high longitudinal and transverse rigidity. Compared to solid plastic sheets, rectangular tanks made from Polystone® P CubX® require very little or no steel reinforcement and are therefore faster and easier to design and build.
The sheet is also suitable for permanent contact with a large number of different chemicals, thanks to the proven chemical resistance of Polystone® P CubX® cover sheets.
Flame retardancy
In response to high demand for a flame-retardant version, Röchling has now developed Polystone® PPs CubX®. With a flame retardancy rating of B1, Polystone® PPs CubX® is suitable for applications with strict fire safety requirements, such as fans, exhaust systems and demisters, as well as for applications such as covers and pumps and in the electronics industry.
Matthias Klein, Product Manager for CubX®, explains: “Polystone® PPs CubX® combines high efficiency with increased safety. Designers can cut down on the use of steel reinforcement, thus saving time and resources. With the new, flame-retardant version, these advantages can now also be used in sensitive areas of application.”
Positive feedback from a conservative market
Röchling collaborated closely with tank builders for the development of Polystone® P CubX® and made full use of their experience. The launch was very positively received by the market.
In 2018 Röchling presented Polystone® P CubX® to an international audience of specialists at three trade fairs: Surface Technology in Stuttgart, ACHEMA in Frankfurt and Intergalva in Berlin. The visitors were very interested in the innovation and scrutinised it critically. Klein reports: “We had detailed discussions with many interested parties about the characteristics of the product. Experience has shown that tank and plant builders heavily emphasise safety for good reasons and don’t utilise new products unreservedly. Many project examples and application cases show that we are headed in the right direction. Polystone® P CubX® is already a popular material for tank and plant building. However, there were frequent requests for a flame-retardant version that would enable designers to exploit the advantages of CubX® in sensitive areas of application as well. We are pleased to meet this requirement with Polystone® PPs CubX®.”
