1. where can plastics be used?
2. what are the advantages of plastics?
3. do plastics resist to corrosion?

7. переведите письменно на язык, используя текст.
1. одно из преимуществ пластмасс то, что они имеют легкий вес и устойчивы к коррозии.
2. пластмассы многими ценными свойствами.
3. пластмассы могут быть использованы в строительстве.

the word "plastic" is a general name given to a group of materials because it means "capable of being molded". the word however, is used to describe not only the material which can be molded but also the material obtained, after it has been fabricated into an object and may no longer be moldable. plastics are the wonderful engineering materials of the modern age, provided that they are properly employed. they posses a great variety of valuable properties and can be used in a wide range of things.
it is necessary to know the nature and behaviour of plastics, their general advantages and disadvantages.
the advantages of the plastics materials include:
a) the ease of fabrication and adaptability to mass production methods at low unit cost.
b) resistance to corrosion.
c) plastics are good thermal and electric insulators, all having dielectric strength.
d) plastics can be easily combined with other materials like wood, fibers, paper and combine light weight with good strength аз wall. the highest strength is obtained with glass fibre and this reinforcement is now used to a considerable extent.
having made a rather modest appearance in the turn of the century as substitutes for some costly materials, plastics have now invaded all branches of industry, agriculture, household needs, medicine and even art. plastics are used in building industry, some of them are extensively used for finishing the interior of buildings.
