Two common types of cloth are constantly competing in today's market. Cordura, produced by a company named Invista, and Kevlar, produced by chemical giant DuPont. While extremely durable and resistant to damage, a debate has raged over which product is better, or at least more appropriate for certain applications.
Kevlar is a trademarked, aramid fabric that is currently owned by DuPont. Aramid fabrics are those that have no melting point, have extraordinary weight-to-strength ratios and a very low flammability. It's for reasons like these that Kevlar is used to make safety equipment such as tie straps, bullet-proof vests and flame retardant clothing.
Cordura fabric, for those who haven't heard of it, was also developed by DuPont. However, today Cordura fabric is primarily made by a company called Invista. Cordura is a variety of nylon which is extremely tear and scuff resistant, and whose strength-to-weight ratio is quite high. Cordura fabric is used when fabric durability is paramount, and it's often found in products like tie straps, parachutes, blade sheaths and other gear that must undergo rough treatment.
Times to Use Kevlar
Kevlar, as an aramid fiber, is best used when heat will be an issue. For flame-retardant clothing, tie straps and even packaging, Kevlar is a far better option. Because the fabric has no melting point and is extremely inflammable, its greatest strengths are that it can stand the heat and keep people and products safe from said heat.
Times to Use Cordura
Cordura fabric is not as heat resistant or safe as Kevlar. However, Cordura fabric is specially made to be long lasting and to endure. Products such as heavy-duty luggage, overalls and even parachutes and tie-down straps that will need to hold up under a great deal of pressure are all products that might be better served made out of Cordura fabric.
Price will always be a concern when it comes to which product to use. Both of these products are brand name, and in many cases the price will be roughly equivalent. Additionally, both of these products are better than unbranded versions of the same fabrics. When trying to decide between Kevlar and Cordura fabric, however, the only guide you can use your needs for your equipment.
