plastikai
Plastikai is a term used in some languages to refer to plastics, a broad family of polymer-based materials, most of which are synthetic or semi-synthetic. Plastics are characterized by their moldability, durability, and versatility, enabling applications from packaging and textiles to electronics and automotive components.
Chemically, plastics are polymers—long chains of repeating monomer units—produced by polymerization or polycondensation. They often include
Common thermoplastics include polyethylene, polypropylene, polystyrene, polyvinyl chloride, and the polyesters such as polyethylene terephthalate. Thermosets
History: The emergence of synthetic plastics began in the late 19th and early 20th centuries, with Bakelite
Environmental and policy context: Plastics pose environmental challenges due to persistence, fragmentation into microplastics, and waste
