In the blizzard of news reports about Earth Day, you likely will hear quite a bit about how individuals, businesses and governments are focusing on "sustainability." But it's less likely that you will hear much about how plastics help us in our collective pursuit of sustainability.

That's unfortunate.

Even a cursory look reveals the many ways that plastics...]]>Mon, 1 Apr 2013 00:00:00 Plastics Engineering, "Next generation UV stabilized, impact modified Polyacetal copolymer (POM) for automotive interior applications."http://www.thefreelibrary.com/Next+generation+UV+stabilized%2c+impact+modified+Polyacetal+copolymer...-a0327108910
Polyoxymethylene (POM) is a semi-crystalline polymer that exhibits good stiffness and tensile strength, but has inherently less notch impact strength compared to more amorphous polymers. Traditionally, several different types of impact modifiers have been used to improve the impact strength of POM. The goal has been to obtain a polymer that has improved impact strength, but still retains...]]>Mon, 1 Apr 2013 00:00:00 Plastics Engineering, "SPE recognizes industry leaders' achievements at ANTEC."http://www.thefreelibrary.com/SPE+recognizes+industry+leaders'+achievements+at+ANTEC.-a0327108911
