Key features

  1. Type: There are several types of Kevlar available, depending on the application. The type should be chosen according to the specific purpose of the product, such as ballistic protection, heat protection, or corrosion resistance.
  2. Thickness: The thickness of the Kevlar fabric should be chosen based on the level of protection or strength desired. Thicker layers provide more protection but may be heavier and more expensive.
  3. Durability: Check the product specifications in order to determine the Kevlar's durability. Generally, Kevlar is very durable, but certain types may not be as strong as others.
  4. Weight: The weight of the Kevlar fabric should be taken into consideration, especially for items that need to be worn or carried. Consider the intended function when selecting the weight.
  5. Price: Kevlar comes in a variety of price ranges depending on the type and thickness desired. Shop around to find the best deal.

Important considerations

Pros

  • Strength: Kevlar is an incredibly strong material that is five times stronger than steel but much lighter in weight.
  • Heat Resistant: Kevlar can withstand temperatures up to 500°F without suffering any damage.
  • Cut and Abrasion Resistant: Kevlar is highly resistant to cuts and abrasions, making it ideal for use in protective clothing and gear.
  • Chemical Resistance: Kevlar is resistant to most acids, alkalis, and other chemicals which makes it an ideal material for protective clothing and gear.
  • Flexibility: Kevlar is very flexible and can be bent and twisted into a variety of shapes without losing any of its strength.

Cons

  • Cost - Kevlar is a very expensive material, and as a result, it can be difficult to source for large-scale projects or to make large purchases.
  • Durability - Kevlar is very strong and durable, but it is not indestructible. It can be damaged by UV light, extreme temperatures, and chemicals.
  • Weight - Kevlar is a very strong material, but it is also quite heavy and can be difficult to work with in some applications.
  • Flammability - Kevlar is not highly flammable, but it is not flame-resistant. It can melt and be damaged if exposed to an open flame.
  • Chemical Resistance - Kevlar is not very resistant to many chemicals, and therefore may not be suitable for some applications.

Best alternatives

  1. Aramid Fibers (Twaron, Technora, etc.) - Synthetic fibers made from polyamides, considered to be a good alternative to Kevlar.
  2. Carbon Fiber - A strong, lightweight material made of carbon atoms in a sheet-like structure.
  3. Spectra/Dyneema - A synthetic fiber made of ultra-high molecular weight polyethylene.
  4. Vectran - A high-strength liquid crystal polymer.
  5. Nomex - A heat-resistant, synthetic material.

Common questions

  1. What is Kevlar?
    Kevlar is a synthetic fiber that was developed by DuPont in 1965. It is well-known for its strength and light weight, and is commonly used in ballistic-resistant body armor, car tires, and cut-resistant gloves.
  2. What is Kevlar used for?
    Kevlar is most commonly used in applications requiring extreme strength and durability, such as body armor and bulletproof vests, as well as cut-resistant gloves, car tires, and reinforced steel cables.
  3. What are the benefits of Kevlar?
    Kevlar is known for its strength, light weight, and durability. It has a high tensile strength, meaning it can be used in applications requiring high levels of force. It is also able to resist high temperatures, making it an ideal choice for applications that involve extreme temperatures.
  4. What is the difference between Kevlar and other materials?
    Kevlar is more resistant to impact and temperature than other materials, such as steel. Kevlar is also much lighter than steel, making it ideal for applications where weight is a factor, such as body armor.
  5. How can I buy Kevlar?
    Kevlar can be purchased from online retailers or from specialty stores. It is also available in bulk from suppliers and manufacturers.
  6. What safety precautions should I take when working with Kevlar?
    Kevlar can irritate the skin, so it is important to wear protective gloves and clothing when working with it. It is also important to avoid breathing in the fibers, so it is recommended to wear a dust mask and protective eyewear when cutting or grinding Kevlar.

Trivia

In the early days of Kevlar's development, it was mistakenly referred to as 'K-Lar'. The name was coined in 1971 when an employee of the DuPont company accidentally mispronounced "kevlar" when talking to a customer, and the name stuck. The mistake has since become an amusing part of the Kevlar story and is still referenced today. Source: DuPont
