February 6, 2015

Harvard Study Confirms Genuine Rulon Materials Superior to CounterfeitWe’ve just read a new study from Harvard University* that confirms what we’ve often mentioned here on Tech Talk – genuine Rulon® materials are far superior to their look-alike counterfeit components.   Yet counterfeit Rulon continues to be a big challenge in the plastics industry, with literally dozens of compounders selling (what they claim to be) “genuine” Rulon, when in fact these materials are often a blend of inferior resins. 

How can you Recognize Genuine Rulon and Avoid Counterfeit?  We’ve got a guide for that!
