I love a gas iron I have and use to help many friends with it, fixing their plastic things. Portable soldering irons are also good to use at work, caring on your bag or far from plugs. High temperatures applied on polymers also produces toxic smoke. If the plastic reaches too high temperatures it can loose its original properties and get weaker, breaking easier. Besides ordinary ones, which you just plug on electricity, you can choose one in which you can set the temperature. There are many types of soldering irons and stations. If you already have a soldering iron, just use it. In these cases the welding process won't work at all. Decomposition is more common to see in plastic exposed to sun and rain, but can happen to indoor plastic as well. Note: some plastic are already in a decomposition state, they break quite easily, almost crumbling by itself. Sometimes, when the plastic is too thin or you might have lost some piece or need to seal it for liquids or if the piece suffers big tensions you might need those items. Instant glue, soldering arms or other way to keep parts in place that you are welding.If your plastic is thin, missing a piece, needs to be sealed for liquid, or under tension, you may also need: The optional flat tip will improve the results, but it's possible to do without it.


I will show you one of various techniques I've seen to fix plastic. It's impressive the number of things that are just discarded and that could still be useful: I often take a soldering iron in my back pack and offer to fix people's plastic everywhere. I've turned myself into an addict of soldering plastic. A huge number of day to day things that we use are made of different polymers that most people just throw away as they get broken.

After learning how to fix broken plastic I realized how plastic is everywhere. Plastic is the material of the 21st century. Para meus colegas de língua portuguesa tem um vídeo tutorial no youtube. If you're in a rush jump to the Soldering step, which will be enough for many cases.
