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

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 tesnení coatings nátery, povrchy
• electrical insulation izolace elektrických
  vodicu hose - hadice

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 povrchStealth tajný,skrytý
