At the duration of last century plastics have become an essential component of our culture. In 1984 the production of plastic exceeded for this first time of steel. In 1934A 10.000 tons of  plastic materials were produced worldwide, in 1949 the number reached them e 1.000.000 tons and in 2006 there manufactured 205.000.000 tons. The rhythms of growth of use of material are so much rapid what today we cannot imagine that would have developed the twentieth century without this.

 In the inquiring subject an effort of presenting the analytic stages of production of plastic object thaw the commercial use of material is not consistent with our knowledge regarding itself.

 Through the historical retrospection we sought the reasons for which plastic became so popular in a small period. The historical retrospection has led us to the conclusion that the plurality of plastic materials and the possibility of transformation of its properties kept us a constant interest. The development of industrially produced plastic in combination with more, led us to the search of their chemistry as well as their properties. The designing of either materials of or architectural work with the material purposes, the knowledge of ways with which we can fabricate the material. Being designers our final objective was their discovery. The next step was to mention the ways anyone can form the object.

 Finally the knowledge we received was developed via the architectural examples to elect the relation of the properties of the material, concerning choices that become through theduration of planning.
