Plaster of Paris Powder ‘POP’ 40KG

Description:

Plaster of Paris commonly known as POP is made up from gypsum. Plaster of Paris contains the calcium sulfate hemihydrates (CaSO4·0.5 H2O). This is prepared by heating the gypsum which contains calcium sulfate dihydrate (CaSO4·2H2O) to a temperature about 150oC (120-180oC). Certain additives are added when heating. Plaster of Paris is a fine, white powder. When it is hydrated it can be used to mould things, and when allowed to dry, it hardens and retains the shape it is set to before drying.
