Plastic is everywhere in our day to day lives – but, of course, ‘plastic’ is just a catch-all term for a range of different chemical substances. This graphic takes a look at some of the more common plastics we encounter on a regular basis, and examines their chemical structures. Below, we’ll also talk a little about how these plastics are created.
With the new season of the Premier League kicking off this weekend, it seemed a good time to take a look at the chemicals that make up your average football shirt. Even if the start of a new football season isn’t the kind of event to fill you with excitement, it’s still intriguing from a chemistry perspective to examine the different chemical materials used and the properties that they lend the finished shirt.
You’ve probably read of the recent death of Stephanie Kwolek, the American chemist who discovered Kevlar. Most people have almost certainly heard of Kevlar, in the context of bullet-proof vests, but fewer are probably aware of the vast range of applications it has, or the chemical reasons behind its strength.
A number of chemical materials are used in the manufacture of the Brazuca, the World Cup football. The majority of these materials are polymers; these are very long molecules built up from many smaller component molecules. A simple, everyday example is polyethene, used to make some plastic bags. Different classes of polymers are used to achieve particular properties for the ball.
