Definition
Vermiculite is a natural mineral that expands when heated, forming a lightweight, fire-resistant, and insulating material.
Properties
Vermiculite undergoes significant expansion at high temperatures, creating a barrier that insulates against heat and fire.
The lightweight nature of vermiculite makes it easy to incorporate into various construction materials without compromising structural integrity.
Vermiculite is inherently non-combustible, providing an added layer of protection against flames and heat.
Applications
Used in lightweight concrete, plaster, and other building materials to enhance fire resistance.
Applied as loose-fill insulation or as part of fireproof coatings for structural elements.

Definition
Intumescent materials are substances that expand when exposed to high temperatures, forming a protective layer that insulates against heat and flames.
Properties
Intumescent coatings expand dramatically, creating a thick, insulating layer that slows down the spread of fire.
These coatings adhere well to various surfaces, providing comprehensive protection.
Intumescent materials can be applied to a wide range of substrates, including steel, wood, and concrete.
Applications
Applied as coatings on steel structures to delay the onset of structural failure during a fire.
Used to protect wooden surfaces, preventing rapid ignition and slowing down the combustion process.
Integral in creating fire-resistant barriers within buildings to contain and control fire spread.
