2.  Introduction
 History
 Production
 Properties
 Application

3. Nomex is the brand name of a heat and flame
resistant textile made by the DuPont Chemical
Company.
The structure of one molecule is given bellow

4. Nomex was officially introduced in 1967
The credit for this excellent invention goes to
Dr Wilfred Sweeny (1926-2011), a Scottush-
born scientist working at the world-famous
DuPont laboratory in Wilmington,Delaware
that also spawned nylon and Kevlar. While
researching polymers,he developed one
particularly good thermal properties that
could be woven into a very tough fiber

5. Nomex is produced by a condensation
reaction from m-phenylenediamine and
isophthaloyl chloride. It is generally made in
the USA and Spain.

6. Process of creation:
1) Adding binding particles
2) Removing CaCl2
3) Turning into paper
4) Drawing
5) Clothing
