Reaction injection moulding Covestro and Arcesso Dynamics announce breakthrough in solid-surface manufacturing
A new manufacturing technology developed by Covestro and Arcesso Dynamics is the first-ever to use reaction injection moulding (RIM) on aliphatic polyurethanes. This was previously considered impossible.
Materials company Covestro and Arcesso Dynamics, a manufacturer of custom polyurethane parts, have launched Arfinio at K 2022 plastics trade fair in Düsseldorf, Germany. The solution is based on reaction injection moulding (RIM) on aliphatic polyurethanes. Previously considered impossible, this technology enables manufacturers to benefit from new combinations of design freedom, functional performance, and sustainability in multiple solid-surface and injection-moulded applications.
Arfinio material is made by injection-moulding of a combination of high-performance liquid polymers and unique minerals. This produces seamless shapes without requiring sheets. In this way, the technology combines the key benefits of aliphatic chemistry, injection molding, and solid surfaces: mechanical resistance, light-stability, and repairability, as well as low product weight, quick production, and improved design freedom.
These properties are now opening new possibilities in applications including an Estoli shower plate, and a luxury design chair. Its formulation can also be supplemented with antibacterial additives, enhancing hygiene on high-touch surfaces. The thermal coefficient of Arfinio makes it warm to the touch, and its texture and colour can be customised. This also allows for backlighting in electronic applications.
Arfinio also contributes toward a more circular, sustainable world. Its high impact, abrasion, and chemical resistance properties give it a long service lifetime. Additionally, as a monomaterial, it can be easily repaired by sanding or milled and recycled into new products.
