Fire Protection

Question 1

What is intumescence?

Answer 1

The ability to expand on the application of heat. Intumescent materials expand when they get hot, creating a thermal barrier to the material underneath, providing fire and heat resistance.

Question 2

in what ways to intumescent materials provide fire resistance?

Answer 2

1. by forming a thermal barrier to the underlying materials due to expansion.
2. the expansion is endothermic, so it absorbs heat.
3. the expanded layer can form a carbon layer providing thermal insulation.

Question 3

what is the name of the LyondellBasell intumescent resin based on expanding graphite?

Answer 3
