As an Introduction to Technical Plastics we usually tend to think that all of them are the same, but this is far from reality. There is a very wide variety, manufactured through different methods and techniques, they originate, in their clear majority, in raw materials obtained from chemical plants from fuel derivatives.
For our activity, we use as reference what are known as “technical plastics or engineering plastics”.
They are a limited group of materials used for the manufacture of piece of mechanisms, which are used in the most diverse productive installations, in any industry.
Technical plastics are materials that are capable of resisting loads and speed that other plastics cannot which are used to manufacture bins or other commonplace components.
Technical plastics offer advantages and disadvantages in relation to metals. Further on we will provide more details, but as a highlight technical plastics are of the lightest materials available.
It is important to select the appropriate technical plastic, based on each application and its parameters: resistance, clearances and tolerances.
Technical Plastics Acronyms
The following are a few acronyms and their general denominations, according to ISO 10438/ ASTM 16008 / DIN 7728. Of the 56 generic denominations, not considering the different combinations of these products, we highlight 17 that correspond to our specialties.
|HDPE||Polietileno de alta densidad|
|PAI||Poliamida – imida|
|PET||Polietileno teraftalato, poliéster|
|PPS||Sulfuro de polifenileno|
|PVDF||Sulfuro de polivinideno|
|UHMWPE||Polietileno de ultra alto peso molecular|
In the next post we will explain how we obtain the technical plastics used for our activity, which is focused on mechanization by chip start, in machine – tools.
See you next time!
