What type of clothing materials are worn by astronauts and firemen and why

Dear Student,

The clothing material of fireman and astronauts contains kevlar and nomax.

Properties of Kevlar :
1)They are very strong and very light,therefore easy to wear.

2)It does not melt like usual plastic.

3)They are unaffected by water.

4)They can be ignited but they can be put out very easily.

5)They can resist attacks from acid,base and harmful chemicals.

Properties of Nomax :
1)They also have strong and light structure like kevlar but comparitively less than kevlar.

2)They are highly heat resistant but very poor conductor of electricity.

3)They do not melt at high temperature.

4)They have better resistance against UV light.

5)They also do not react with water.

Regards
