This is a model to explain the occurrence and structures of crystalline regions of polymers such as polyethylene. These regions contain parallel strands lying alongside one another. The mutual attraction of like-for-like holds the strands together in this highly ordered array. Many of the strands ...

The term polymer is often used to describe plastics, which are synthetic polymers. However, natural polymers also exist; rubber and wood, for example, are natural polymers that consist of a simple hydrocarbon, isoprene, according toEncyclopedia Britannica. Proteins are natural polymers made up of a...
say, common salt. To contrast the difference, the molecular weight of common salt is only 58.5, while that of a polymer can be as high as several hundred thousand thousands. These big molecules or 'macro-molecules' are made up of much smaller molecules. The small ...

Polymer banknotes are made using a layered printing process. Starting with a polymer sheet, each element is added to the banknote until it is complete, cut and tested for imperfections. The Bank of England produces over a billion notes every year and every note is made the same. How is ban...
Notably, the insulator between electrodes in LiPos is made of a micro-porous polymer. In contrast, a traditional porous film separator is used for Li-ions. Another difference is in the battery packaging. Li-ion batteries usually come in a stainless steel or aluminum case, often cylindrical in...
What are They Made of? You must be curious how these records survive through the passage of time and are still able to deliver rich sound. Primarily, polyvinyl chloride (PVC), a synthetic plastic polymer, is used to make these records. However, here’s a breakdown of all the materials an...
PMMA is an important material for many other medical procedures. For instance, it is used to make dentures and fillings because it is easy to dye and quick to form. As a result, doctors can use PMMA material to make dentures and fillings that closely match the size and color of the orig...
