Every morning when you wake up and you back your lunch for work in some kind of container you use this kind of material. Every day that you make coffee or something cold to drink, you make use of hot and cold temperatures to change the form of something. Thermo plastics is most probably be used more than once in your household.

Most of the time when you take a container out of the cupboard you probably does not even think about how it has been made of how they managed to get it in the form or shape that you are holding in your hand. This kind of material can change its shape and form in almost anything. It can change from a very hard and breakable substance to a liquid in very little time.

It will even have the fragile properties as well as the see through properties of glass. This kind of material is also the easiest to recycle. The material can be exposed to the extreme heat until it turns into a liquid form and then it can be poured into a mold and then it will be cooled down.

As the material cools, down it will start taking the form of the mold and when the mold is being removed from the material you will have a new form, shape or even container. Whatever happens to this kind of material, no matter what shape or form it has taken on, after being exposed to any kind of temperature change, it will always be reversible. You will always be able to put the material back to its original shape or form.

When this is heated up, it becomes what is known as homogenized liquid. When the material is frozen and turned to the glasslike, it is really just as breakable as glass itself. Whatever shape or form this material will take, it will always be reversible.

This is why it makes this material such a good quality of recycle material. As mentioned before, there are many kinds of this type of material. The two things that separate the types of materials is the variance in density and crystalline organization that they each have.

The most popular products that is being manufactured and used in everyday life these days is acrylic, polycarbonate, polypropylene as well as polyurethane. The very first material of this kind called celluloid was first used in the mid nineteen eighties and was considered the best materials for most of the next hundred years. Today they have found much better quality materials and them actually only use this Celluloid to manufacture guitar picks. You will find that most of the things that you use in your everyday life are made of one of these kinds of materials.
