Forensic polymer engineering — The study of failure in polymeric products is called forensic polymer engineering. The topic includes the fracture of plastic products, or any other reason why such a product fails in service, or fails to meet its specification. The subject… … Wikipedia
UV degradation — Many natural and synthetic polymers are attacked by ultra violet radiation and products made using these materials may crack or disintegrate. The problem is known as UV degradation , and is a common problem in products exposed to sunlight.… … Wikipedia
Thermal degradation of polymers — is molecular deterioration as a result of overheating. At high temperatures the components of the long chain backbone of the polymer can begin to separate (molecular scission) and react with one another to change the properties of the polymer.… … Wikipedia
