Polymer Journal #4


Each of our prototypes were very similar in material and characteristics. Prototype 1 was made using Gloop and liquid starch, our second prototype was made using liquid starch and solid cornstarch. We combined the two by having prototype 1 as the inner layer and prototype 2 as the outer layer. Since our first two prototypes melted while being in a closed system, we remade three more polymers. The first one (#3) was Stretchtastic, then adding guar gum and corn starch. The second one (#4) was Gloop mixed with liquid starch and solid cornstarch. The last one (#5) was Gloop mixed with liquid starch. All of these prototypes were tested in an open system, to figure out which polymer is best used as the inner layer of our product. After all prototypes were tested, we thought prototype #5 worked the best. For the outer layer, we used prototype #3, but kept it in a closed system to keep the moisture and softness. The limitation of this product is that every time, we needed to detach the two polymers or else they will either both melt in a closed system or harden in an opened system. Prototype #5 worked the best for the inner layer because when it hardens, it holds its shape and is durable. It is also easy to attach and detach without staining or damaging the table or the polymer itself. Prototype #3 was the best outer layer because it is sticky and moldable enough to be able to cover the hard shell, while being thick enough to round up the sharp edges. Our product also included hangers that were attached to the bottom. We decided to use pipe cleaners because we weren’t able to make a polymer that was best used as hangers. Also, if the hardened polymer were to be attached to a polymer that was kept in a closed system, it will melt and soften overtime. Using the pipe cleaners, we found that it was easy to attach and shape. By twisting two pipe cleaners together, it became more durable and stiff. Throughout the Polymer Project I learned the different ways each polymer is made and what material causes the polymer’s physical properties to change. I also learnt the different characteristics each polymer has in both closed system and opened system and how it can benefit our goal of creating a table corner protector with an attached hanger.

Polymer Project – Suazé

Polymer Journal #3

For our polymer project, June, Evelyn and I made a polymer that was able to protect sharp table corners. We wanted a polymer that was sticky for it to hold onto the corners, thick enough to prevent injuries while being soft enough to be molded to the shapes desired. Our first prototype was made with the Gloop recipe then adding 2mL of liquid starch. This prototype was molded to a table corner for testing. Few days later, the polymer hardened and was similar to plastic. The polymer also became a lot thinner, but it was durable and could be reused without damaging furniture or the polymer itself. Since our first prototype became rough on the edges and no long had the protecting characteristics, we decided to cover it with another polymer made with the same materials but adding a scoop of solid cornstarch. We covered the previous polymer with the new one we created and tested it. We tested our second prototype by attaching it to the table corners. Since the inner layer of the polymer was hard, it was easy to attach and detach it while having a soft outer layer to prevent injuries. However, when we stored the polymer in a closed system, it melted, so we had to start over using the same base materials. In class, we made three different polymers. Two of the polymers were the same as prototype 1 and 2. For the third polymer, we decided to make a Stretchtasitic.  All three of them were moldable and were securely attached to the table corners for testing. As a ending result, our third prototypes will include the same characteristics as our first two prototypes; a hard shell that we will use as the inner layer and the soft and thick outer layer.
