Polymers

1. uses of polymers

   • Packaging materials must be strong, light and flexible
   • waterproofing for tent fabrics must repel water.
   • Dental polymers for crowns and dentures are designed to harden when exposed to ultraviolet light
   • Wound dressings must breathe and hydrogels must remain moisgture for rapid healing.

2. Reasons for recycling

   • Most polymers are produced from non-renewable crude oil. They are not biodegradable. They take up space in waste dumps and landfill sites.
