First markets: tyres and later vests.
Meta-aramid (1960s) had the fire-fighter story; para took strength.
Akzo (now Teijin) European para-aramid.
NIJ ballistic standards met para-aramid packs.
アラミド pulp in friction materials.
Dyneema/Spectra took some ballistic mass.
Geopolitical fibre lists.
Yarn as strength member.
Hard to remelt; chemical routes immature.
