skumläckor

Skumläckor, literally translating to "foam leaks" in Swedish, refers to a phenomenon observed in certain types of polyurethane foam. These leaks typically manifest as a sticky, liquid-like substance seeping out from the foam, often after a period of time. The cause is usually attributed to the degradation of the foam's chemical structure, particularly the plasticizers and other additives used during manufacturing. Over time, these components can break down, especially when exposed to heat, moisture, or UV radiation, leading to the formation and expulsion of the viscous fluid.

This issue is commonly encountered in older furniture, mattresses, and insulation materials made with polyurethane foam. While the substance itself is generally not considered toxic, it can be unsightly and difficult to clean, leaving residue on surrounding surfaces. The smell associated with skumläckor can also be unpleasant. Mitigation and prevention strategies focus on controlling environmental factors that accelerate foam degradation, such as maintaining a stable temperature and avoiding prolonged exposure to direct sunlight. In cases where the leakage is severe, replacement of the affected foam product is often the most practical solution.
