  Kevlar Wick and Kevlar Cord (Fire Wick). What is Kevlar?
Because Kevlar fabric is self extinguishing your fire toys will extinguish as soon as the fuel saturating your kevlar wick has been burnt.
Kevlar cloth can also be used in kevlar sleeves, to protect your arms when performing wraps and other poi tricks.
We use a variety of weights, measured by diameter/width: kevlar string (1/8"), kevlar cord (1/4"), kevlar rope (3/4"), kevlar tape (2"), kevlar tape (4") and sheets of kevlar cloth.

  Kevlar - Wikipedia, the free encyclopedia
Kevlar 29 is used in industrial applications such as cables, asbestos replacement, brake lines, body armour (knife or bullet resistant).
Kevlar 49 is considered to have the greatest tensile strength of all the aramids, and is used in applications such as plastic reinforcement for boat hulls, aeroplanes, and bikes.
Kevlar derives a portion of its improved strength from inter-molecular hydrogen bonds formed between the carbonyl groups and protons on neighboring polymer chains and the partial pi stacking of the benzenoid aromatic stacking interactions between stacked strands.

 Kevlar - WOI Encyclopedia Italia
Kevlar (poly-paraphenylene terephthalamide) is the DuPont Company’s brand name for a synthetic material constructed of para-aramid fibers that the company claims is five times stronger than the same weight of steel, while being lightweight, flexible and comfortable.
Kevlar is a type of aramid that consists of long polymeric chains with a parallel orientation.
Kevlar's main weaknesses are that it decomposes under alkaline conditions or when exposed to chlorine.

 AMA INSIDER | March 2006 | Composite Materials: Kevlar
Kevlar fiber, originally developed to replace steel in radial tires, has found increasing use in the belts of radial car and truck tires, where it saves weight and increases strength and durability compared to steel belts.
Kevlar 49 aramid fiber is characterized by low-density and high-tensile strength and modulus.
Kevlar 49 aramid is used in high-performance composite applications where lightweight, high strength and stiffness, vibration damping and resistance to damage, fatigue, and stress rupture are key properties.

 Kevlar   (Site not responding. Last check: )
Kevlar was invented in 1964 by Stephanie Kwolek at the Dupont laboratories in Wilmington, Delaware in the United States.
Kevlar is an aramid, a term invented as an abbreviation for aromatic polyamide.
Kevlar is also used in brake and transmission friction parts, gaskets, ropes and cables, composites, fibre optic cables, circuit board reinforcement, tires, automotive belts and hoses.

 USATODAY.com - DuPont chemist had critical role in developing Kevlar   (Site not responding. Last check: )
The chemistry behind the bullet-resistant Kevlar and other man-made fibers has consumed decades of work for Gabara, who was born in Poland during World War II and left for the United States in 1968.
Kevlar's safety aspects were known before its commercial introduction in the 1970s, Gabara said, but the company's plans for the product were different when he came to the Richmond area in 1976 to improve the manufacturing process and increase production at DuPont's Spruance plant.
Kevlar, for example, is twice as light as it was 20 years ago, making it more effective for personal protection.
