The fire rating of 5/8 type X gypsum board is typically around 1 hour.
Type C gypsum board meets and exeeds the fire resistance requirements of a type x board. It has mineral additives in the gypsum core that expands when exposed to heat. This expansion holds the board together longer during fire exposure. It is referred to by the Gypsum Association as "Improved Type X" board.
There are different types of gypsum boards depending on the purpose. The main ones include: • Regular gypsum board – for basic wall and ceiling use • Moisture-resistant board – for kitchens and bathrooms • Fire-resistant board – used in areas needing extra safety • Soundproof or acoustic boards – good for offices or commercial spaces Brands like Buildwell offer high-quality boards specially made for Indian interiors.

The most commonly used tool for cutting in gypsum board is a basic utility knife, the type that has a lock on the side and pop off blades.
Type of fire it will extinguish, and the capacity of the exinguisher
Yes. They are rated for the type of fire they can be used against, and the capacity of the extinguisher.
This boardis similar in composition to Type X drywall, except that it has more glass fibers, and, it has another ingredient in the gypsum core. This ingredient is a shrinkage-compensating additive, a form of vermiculite. When exposed to high heat, the gypsum core shrinks but the shrinkage-compensating element expands at about the same rate as shrinkage occurs in the waterdepleted gypsum. The gypsum core then is more stable in a fire and remains in place even after the combined water in the gypsum has been driven off.

A 1/2 panel will last 30 minutes or so in a house fire. Fire rated Type X 5/8 will last about 90 minutes.
Gypsum is actually a major rock forming mineral. Rock gypsum is a chemical sedimentary rock.
