Kevlar is a high-strength material that can withstand significant forces and impacts, making it ideal for use in protective applications such as bulletproof vests. In contrast, Teflon is a polymer known for its non-stick properties and resistance to heat and chemicals. The two materials are different, but they serve distinct purposes and can be used together in the right applications.

Both Teflon and Kevlar are synthetic materials developed by DuPont. Kevlar is made from a type of aramid fiber called poly-para-phenylene terephthalamide, while Teflon is a fluoropolymer that was discovered by accident in 1938. Both materials have a variety of useful industrial applications.

Woven Kevlar fabric coated with PTFE is a good choice for highly demanding mechanical applications that require both excellent tensile strength and low friction. These include heavy conveyor belting, drying belts for wood pressing and laminating, and release sheets in carbon fiber gasket applications.

The tribological behavior of woven PTFE/Kevlar fabric was investigated by reciprocating friction tests and surface analysis using a stereo microscope, a field emission scanning electron microscope (FESEM), and an energy dispersive spectrometer (EDS). The results show that the contact wear scar of the PTFE/Kevlar material decreased with increasing load and reached its lowest value at a load of 2 N.

Several sports equipment and clothing items are made from Kevlar, including bicycle tires, racing sails, and tennis racquet strings. In addition, Kevlar is an important component in the wicks that fire dancers use to create their flame dancing props. While these wicks are not considered harmful by themselves, the manufacturing process can expose workers to chemicals that can pose health risks. However, the risk is low when the material is used for its intended purpose and following manufacturers’ guidelines.
