pehmittimet
Pehmittimet are substances added to polymers and fibers to increase their flexibility and softness. In practice they are commonly referred to as plasticizers or softeners and work by inserting between polymer chains, reducing intermolecular forces and lowering the glass transition temperature. This enhances workability, flexibility, and impact resistance of the material.
Common types include phthalates (such as di(2-ethylhexyl) phthalate, often abbreviated DEHP or DOP), adipates, and citrate-based
Applications span a wide range of products. The largest use is in PVC-containing materials such as flooring,
Safety and regulation are important considerations. Some phthalates have been associated with health and environmental concerns,
Environmental and lifecycle aspects, including production, use, and end-of-life disposal, influence the choice of pehmittimet in
