What are “Plastics”?<\/p>\n
Plastics are materials consisting of a wide range of synthetic compounds including carbon, hydrogen, oxygen, nitrogen, chlorine etc. derived from petroleum, petroleum gas, coal, plant, air, water, salt etc. mixed with additives and fillers as needed.
\nThese are classified or grouped as ;
\n\u30fbThermosets and Thermoplastics based on thermal characteristics,
\n\u30fbCrystalline and Amorphous based on arrangement of molecules and
\n\u30fbCommodity plastics and Engineering plastics based on heat resistance.
\nRubbers, fibers, paints and adhesives are usually not dealt with in plastics.<\/p>\n
What is “Polymer”?<\/p>\n
A polymer is a large molecule composed of many repeated subunits.\u00a0 Polymers are created by polymerization of many small molecules known as monomers.
\nPolymers include:
\n\u30fbPlastics such as synthetic polymers, Polyethylene, Polystyrene…,
\n\u30fbRubbers such as natural\/biological polymer, Polyisoprene…,
\n\u30fbBiological macromolecules such as Protein, DNA etc.<\/p>","protected":false},"excerpt":{"rendered":"
