Although nylon 6/6 is much more commonly used than polyester (PBT) for injection molding applications, you might be surprised that these materials are relatively similar in properties.
There are, however, a few differences that might make one or the other better for a particular application.
I was walking through a local store the other day when I came across a new line of Rubbermaid food storage containers that intrigued me. What caught my eye was the fact that these containers are crystal clear. They can’t be made of polycarbonate, which is a big no-no for food storage containers because of BPA. The recycling code on the container is #7 which is “other”. Polycarbonate would fall under the 7 recycling code also but so would many other materials. What is this material?

A new geological survey performed in Texas has revealed the largest oil discovery in US history. An area that encompasses Lubbock and Midland Texas is now estimated to have 20 billion barrels of oil and 1.6 billion barrels of natural gas according to CNN. This discovery of shale oil is 3 times larger than the discovery in North Dakota that lead to the oil boom there that started in 2006 and ended in 2015.
You might think that this discovery is really good news for the United States. But there is one problem.
