Etymology:
Meaning:
Intumescent refers to materials that swell or expand significantly upon exposure to heat or fire.
Origin:
The term intumescent was first used in the context of fire protection in the early 1900s. It was initially applied to paints and coatings that expanded and formed a protective, insulating layer when exposed to heat. This layer helped to reduce heat transfer and slow down the spread of fire.
Over time, the term intumescent has been expanded to include a wide range of materials, including:
These materials are typically made from polymers or other organic materials that undergo a chemical reaction when heated. This reaction causes the material to expand and form a protective barrier that insulates and protects against fire.
