Multiple cycles of heating and cooling can be repeated, allowing reprocessing and recycling. These polymers too are amorphous and have infinite molecular weight. Depending upon their chemistry they can be very much like rubber, or as strong as aluminum. Engineering thermoplastics comprise a special performance segment of synthetic plastics materials that offer enhanced properties. In addition, they are resistant to chemicals and have a higher heat resistance. Swell in the presence of certain solvents. Different types of thermoplastics have additional properties that make them especially well-suited to different jobs, but all thermoplastics share the same characteristic of flexibility when exposed to heat and force. Under different heating conditions and by varying the composition of the plastic it is possible to make many different products with differing properties. A thermoplastic, or thermosoftening plastic, is a plastic polymer material that becomes pliable or moldable at a certain elevated temperature and solidifies upon cooling. By heating the polymer, it turns as soft material. Thermoplastics are meltable. resistant to a variety of bases and acids, some solvents and chlorinated hydrocarbons may damage the material, common as DEV - Drainage, Waste and Vent - pipes, only compression and banded type joints used. Thermoplastics represent appx 90% by weight of all plastics consumed world-wide. Polyester resins are known for their excellent combination of properties such as mechanical, thermal, chemical resistance as well as dimensional stability. These behavior and properties depend on their material constituents, their structure, temperature, frequency and time scale at which the material or the engineering component is analyzed.
