what are the different properties of polymers?
243472
Some of the useful properties of various engineering polymers are high strength or modulus to weight ratios (light weight but comparatively stiff and strong), toughness, resilience, resistance to corrosion, lack of conductivity (heat and electrical), color, transparency, processing, and low cost.

Properties of Plastic. Plastics are generally low cost, easy to manufacture, durable, strong for their weight, electrically and thermally insulative, and resistant to shock, corrosion, chemicals, and water.

There are two main types of plastics and these are named Thermoplastics and Thermosetting Plastics. Thermoplastics are made up of lines of molecules with few cross linkages. This allows them to soften when heated and to be bent into a variety of shapes and forms.

The key difference between polymers and plastics is that plastic is a specific type of polymer. Plastics are comprised of a long chain of polymers, where polymers are composed of smaller, uniform molecules.

The advantages of plastics: It is durable, low cost, water resistant, lesser energy and heavy chemicals requirements in manufacture and are light weight.

Properties of bulk matter include key concepts such as stress, strain, elasticity, Hook's law, and other concepts related to fluids such as Pascal's law, viscosity, surface energy, etc.

The chemical properties of polymer discussed here include chemical resistance, chemical permeation, and weather resistance. The major component of the polymer is hydrocarbon which results in hydrophobic property in general. They are usually resistant to polar solvent but will be attacked by nonpolar solvent.
