How are rubber bands made?

Rubber bands come from a huge block of natural rubber. The blocks are  made from the sap of a tree or the resin. Pretty cool right? Who knew it was so natural. Natural rubber has more stretch to it than synthetic rubber bands, hence why we use it to make rubber bands.

The ingredients to make rubber: The sap or resin, processing oil and dye. A few rubber blocks are then put together in a large mixing/kneading machine. This all gets mixed into a big rubber dough.Once a dough like consistency is made, the dough is moved over to another machine, where they make this dough into sheets. It is at this stage that sulphur and a few other things are added to the mix, to make it into the rubbery texture it needs to be.

The rubber will then be sectioned off into small logs, to put in the extruder which then mixes it with talcum powder. This makes it into a tube, by pumping air into the middle. Pretty cool eh? Who knew how to make rubber badness before reading this blog post?

Last bit of the rubber band process

Voila and that’s how rubber is made and formed into bands.
