Polymers toughened with novel elastomeric structures.(TECHNOLOGY UPDATE)
High Performance Plastics, November, 2005
Researchers at Pennsylvania State University are embedding microspheres of polyolefin ethylene-based elastomers into polymer matrices in order to create plastics with improved flexural strength and impact resistance.
Potential applications for plastics that incorporate the elastomers include automobile bumpers that deform and recover rather than crack and splinter, tough computer cases, and ultra violet (UV)-resistant coatings.
Lead researcher Professor T.C. Chung says "Plastics such as PP, PA, PC, epoxy and other compounds are brittle and fracture easily. To overcome this problem, manufacturers usually mix rubber or elastomeric compounds with the plastic, but there are many issues with this approach."
