Full Form of POP
What is POP?
Plaster of Paris (POP) is a quick-setting calcium sulfate hemihydrate powder derived from gypsum through calcination. When mixed with water, it forms a hard, solid mass through a hydration reaction. In India, POP is extensively used in orthopedics for immobilizing fractured bones, in dentistry for making molds and impressions, and in construction for decorative work such as false ceilings, cornices, and ornamental detailing. Its low cost, ease of application, and rapid setting make it a staple in government hospitals and rural healthcare centers across the country. It is also a common material in school science laboratories for model-making and in art classes for sculpting. POP holds significant exam relevance: it is a standard topic in Indian Class 10 and 11 chemistry curricula and regularly appears in competitive exams like NEET, JEE, and state board examinations. Students are expected to know its chemical formula (CaSO₄·½H₂O), preparation method, setting reaction, and key applications. Understanding POP is essential for those pursuing careers in medicine, dentistry, engineering, or architecture. Its versatility across medical, dental, and building fields makes it a fundamental material in both educational and professional Indian contexts.
