• Applications

Kevlar has many applications, ranging from bicycle tires and racing sails to bulletproof vests, because of its high tensile strength-to-weight ratio; by this measure it is five times stronger than steel. It also is used to make modern marching drumheads that withstand high impact. When used as a woven material, it is suitable for mooring lines and other underwater applications.

• Production

Kevlar is synthesized in solution from the monomers 1,4-phenylene-diamine (para-phenylenediamine) and terephthaloyl chloride in a condensation reaction yielding hydrochloric acid as a byproduct. The result has liquid-crystalline behavior, and mechanical drawing orients the polymer chains in the fiber's direction. Hexamethylphosphoramide (HMPA) was the solvent initially used for the polymerization, but for safety reasons, DuPont replaced it by a solution of N-methyl-pyrrolidone and calcium chloride. As this process had been patented by Akzo (see above) in the production of Twaron, a patent war ensued.

• Kevlar Grades

Kevlar K-29 – in industrial applications, such as cables, asbestos replacement, brake linings, and body/vehicle armor.

Kevlar K49 – high modulus used in cable and rope products.

Kevlar K100 – colored version of Kevlar

Kevlar K119 – higher-elongation, flexible and more fatigue resistant

Kevlar K129 – higher tenacity for ballistic applications

Kevlar AP – 15% higher tensile strength than K-29

Kevlar XP – lighter weight resin and KM2 plus fiber combination

Kevlar KM2 – enhanced ballistic resistance for armor applications
