7. Use of Chloroprene The best known are propably wetsuits for
diving or water sports generaly,
which are made of neoprene
(polymerized chloroprene).
wetsuit- neoprén, oblek na vodní sporty

8. Use of neoprene Becouse of its high mechanical and chemical endurance
lot of common things are made of neoprene. Such as gaskets,
corrosion-resistant coatings, electrical insulation, hoses and very
important are also
various medical utilities
Gasket –těsnění; coatings – nátěry, povrchy;
electrical insulation – izolace elektrických vodičů; hose - hadice

9. Use of chloroprene
But chloroprene is also used as a component of various types
of rubbers and modern materials. From mousepads to hi-tech
surfaces of military stealth airplanes, witch „hides“ planes by
reflecting radar waves
Surface – povrch;Stealth – tajný,skrytý
