History of Saint-Gobain Gyproc India Ltd
The company was started as India Gypsum in 1986 as a part of the C. K. Birla Group (Hyderabad Industries). The set up was under technical collaboration with British Plaster Boards (BPB) Worldwide
The first plaster board manufacturing was started in 1986 at a plant based at Jind (Haryana). The plant introduced a value added plaster board category in 1996 with fire resistant boards- better known as GRG. The company started another plant in Chennai in 2000 followed by a plant in Wada (near Mumbai) in 2005. The Wada plant along with plaster boards also manufactures gypsum plasters.
The company was taken over by the Saint-Gobain Group by virtue of a global acquisition of BPB in 2006. The name has been recently changed to Saint-Gobain Gyproc India Ltd. (SGGIL). The company also has a plant for plaster boards based out of Bengaluru set up in 2008.
The Chennai plant is currently not operational due to technology upgrade no longer possible on the earlier installed machinery. The technology is not capable of meeting new consumer demands and product standards.
Gypsum Plasterboards
Gypsum Plasterboards comprise of a natural gypsum slurry core encased between paper liners on the top and bottom. The paper used is of 160 to 200 gsm thickness. The specifications for gypsum plasterboards is defined by the IS 2095- Part 1, 1996.
The usual shape of a plasterboard is rectangular. The most common sizes of gypsum plasterboards are 4 ft x 6 ft or 4 ft x 8 ft. If the shape of the board is in the form of a square, it is called a gypsum tile. Gypsum tiles are most commonly seen in 2 ft x 2 ft size.
Manufacturing process of Gypsum Plaster Boards A plaster board is made of a paper liner wrapped around an inner core made primarily from gypsum plaster. The raw natural gypsum, CaSO4·2 H2O, is heated in a process called calcined to produce the hemihydrate of calcium sulfate (CaSO4·½ H2O). This is done in kettle or flash calciners. The plaster is mixed with fiberglass), plasticizer, foaming agent, finely ground gypsum crystal as an accelerator, EDTA, starch or other chelate as a retarder, various additives that may increase mildew and/or fire resistance (fiberglass or vermiculite), wax emulsion or silanes for lower water absorption and water.
The board is then formed by sandwiching a core of wet gypsum between two sheets of heavy paper. When the core sets and is dried in a large drying chamber, the sandwich becomes rigid and strong enough for use as a building material.
