This is the first in a series on DuPont innovations in materials science that are helping the world's best athletes compete in Beijing, China, and how they play a critical role in delivering maximum performance.
The "S-WORKS" helmet
The quest for lighter, stronger and safer sports equipment has provided added benefits to world-class and recreational athletes - as well as a market opportunity for a number of key DuPont products.
Specialized -- a leading bicycle company based in Califorinia -- is manufacturing the lightest weight bike helmet in the world, made with an innermatrix reinforced with DuPont™ Kevlar®. Athletes competing in Beijing are using the new Specialized "S-WORKS" helmet because it enables larger, deeper channeled vents for extremely minimal weight, increased ventilation, comfort and effortless security. Look for the "S-WORKS" helmet in upcoming triathlon and mountain biking events.
Among other key products used in cycling, DuPont™ Krytox® performance lubricants are used for bicycle components for a smooth, fast ride. Severe performance requirements for bicycle workings such as derailleurs, brake handles, levers and wheels use durable engineering polymers DuPont™ Delrin®, Zytel®, Crastin® PBT or Rynite® PET.
Cycling accessories use Delrin® in sprockets, Hytrel® for inner tubes, Crastin®, Delrin® and Zytel® for switch handles, speedometer components, lamp components and brake handles and Delrin® for bell components. The bike saddles use inserts of Delrin®, Hytrel®, Zytel® and seat supports with Delrin® and Zytel®. Wheels use Kevlar® and Zytel® and the hub uses Rynite®. The buckles and soles of cycling shoes are made with Delrin® and Zytel® and sunglass frames are made with Delrin®, Hytrel® and Zytel®. Bicycles use DuPont™ Imron® coatings for durability and gloss. Kevlar® also is used in tires.
The numbers worn by athletes in Beijing are made of DuPont™ Tyvek®, which is used because it is durable and lightweight.
