Developing melamine-free polyurethane foams

A common foam mattress ingredient is being phased out as a carcinogen, and a UK company is racing to replace it with a safer alternative. Melamine has been a standard flame retardant in polyurethane foam for decades, but the European Chemicals Agency now classifies it as a Substance of Very High Concern, and EU regulations labelled it carcinogenic in 2023. This creates an urgent gap: mattress and furniture manufacturers need a flame-retardant foam that meets UK fire safety standards (BS5852 CRIB-5) without using melamine. Alfrecell, working with supplier Repsol, has already shown in lab-scale chemical analysis that a melamine-free polyurethane foam can work. The challenge now is to optimise the formulation and scale it up to full manufacturing production. If successful, this could change what goes into millions of mattresses, sofas, and upholstered furniture items sold in the UK each year. The new foam would also be recyclable, improving the circularity of furniture waste that currently often ends up in landfill or incineration. For most people, the change would be invisible—a mattress that feels the same, passes the same fire test, but no longer contains a known carcinogen.
