Top 7 Blog Posts of 2018

It has been a very exciting year for us here at SGS Polymer Solutions! From geeking out over polymers to testing some interesting things, we feel that there is no better way to wrap up the year than by sharing the top SGS PSI blog posts written in 2018.

#7 Top 7 Things We’ve Tested

At the beginning of 2018, we rounded up the most interesting items we’ve ever tested at SGS PSI. From NASCAR Stadium seats to artificial tear drops, we’ve done it all! And these are a few of our favorites.  

#6 The Wonderful World of Hydrogels

You’re probably a frequent user of hydrogels, but do you know the science behind them? Hydrogels are hydrophillic, or water-loving, polymers that are capable of some pretty amazing things. Because they’re biocompatible and bioabsorbent, hydrogels hold great promise for continued drug delivery and implantable medical devices.

#5 Why is the Sky Blue?

How many times have you been asked by a child, or an adult for that matter, why the sky is blue? What do you say?

We explored the science behind this question and found that there are actually multiple reasons why the sky is blue. One reason being that the molecules in the sky are scatterers, which means we discount the illuminant (sunlight) and see only the scattered blue wavelengths. The second reason is that we’ve been cognitively trained to see the sky as blue.

What seems like such a basic question can lead to an interdisciplinary discussion. Read this post, and the next time you’re asked this question, you can answer with confidence!

#4 Petroleum Jelly: Is It Safe?

While a jar of petroleum jelly can be found in virtually every household in the United States, some consumers have concerns about whether or not petroleum jelly is safe to use.

A common myth is that this jelly is a dangerous chemical byproduct of petroleum. However, with all of the purification and testing that petroleum jelly is required to go through, this consumer product is safe to use.

#3 Silicon vs Silicone

Two substances that sound very similar in prefix and ending can be widely different and useful in very different applications. A great example of this is the distinction between silicon and silicone. While they sound similar and are even used in conjunction with each other in certain applications, these two substances perform incredibly different tasks.

#2 Why is Rubbing Alcohol Cold?

We enjoy writing about everyday science so much that it has its own category on our blog! From dry erase markers to dishwasher pods, we enjoy exploring the science behind everyday objects like this one.

Have you ever noticed that rubbing alcohol feels cold to the touch, even at room temperature? This is caused by a concept known as evaporative cooling.

#1 Polyhydroxybutyrate: An Exciting Biodegradable Polymer

If you’ve followed our blog for a while, then it will come as no surprise that we geek out over polymers on a regular basis. This polymer was no exception.

When people think of plastics, environmentally-friendly usually doesn’t come to mind. However, a polymer known as Polyhydroxybutyrate (PHB) could change the common perceptions about plastic. At SGS PSI, we get the opportunity to experiment with some materials that are not only useful in industry but good for the environment as well. That’s why we’re excited about PHB!

There you have it! Those are our top seven blog posts written in 2018. We hope you enjoyed reflecting over the past year with us.

If you have an everyday science question, we encourage you to reach out in the comments below. We may write a blog post about it in the new year!
