Plastic composites

Abstract

Plastic composites are combinations of a polymer matrix and a solid reinforcement material. Thermosetting and thermoplastic resins are used as matrices of plastic composites. Epoxy resins are the most common thermosetting resins in modern plastic composites. Dermatitis is a common occupational complaint in this industrial area. Skin hazards include irritant and allergic contact dermatoses and contact urticaria, as well as thermal or chemical burns. Epoxy resin compounds are the most common cause of allergic contact dermatitis from plastic composites. Man-made mineral fibers (MMMF) used for reinforcement are the main cause of irritant contact dermatitis in the manufacture of composite products. The development of occupational dermatitis depends on the materials (resins, reinforcements, and auxiliary substances), specific work tasks, working methods, workplace environment, and personal protection.
