This application demonstrates how the use of polymers goes beyond the simple availability of a technical alternative, but makes it possible a complete redefinition of the product, introducing solutions previously difficult to achieve using traditional materials. |

OTHER CHALLENGES Despite these advancements, the path to a wider implementation of metal replacement solutions still faces some challenges. A major one is the conservatism of some industrial sectors, which are reluctant to abandon conventional materials and technologies. Added to this are certification requirements, which are particularly stringent in areas such as plumbing and heating, where components must guarantee reliable performance even after decades of use. F urthermore, some more advanced technological solutions, such as those based on filament fibres, are still penalised by high costs compared to metals. Overcoming these barriers requires joint efforts between material manufacturers, designers and end users, based on expertise, testing and in-depth validation.
WATER MANAGEMENT – A STRATEGIC TARGET A particularly interesting sector is water management, traditionally relying on metals such as brass. Recent regulatory developments— in particular the reduction of lead content— are changing the economic balance and opening up new opportunities for engineering polymers.

In this area, metal replacement offers clear advantages, but also requires high-performance materials capable of ensuring durability, safety and regulatory compliance. „ You can‘ t use just any plastic,“ Spini observes, „ we actually need high-performance solutions lasting 20 or 50 years.“
TOWARD A NEW INDUSTRY OF MATERIALS Metal replacement is part of a broader context of industrial transition, driven by megatrends
|
such as electrification, sustainability and the circular economy. In this scenario, RadiciGroup is focusing on innovative solutions, including recycled and bio-based materials as well as on a collaborative approach with customers. The path is clear: the future of material engineering will increasingly be linked to the ability to combine high performance, reduced environmental impact and design flexibility. In this context, metal replacement represents one of the most effective tools to drive this evolution. |
