POLYMERS CLASSIFICATION

POLYMERS CLASSIFICATION

1. POLYMERS ARE DEFINED AS MACROMOLECULES THAT ARE OBTAINED BY THE UNION OF ONE OR MORE REPEATING SMALL MOLECULES ALONG A CHAIN.

   • they are classificated by
     • NATURAL
       • THEY ARE THOSE COMING DIRECTLY FROM THE VEGETABLE OR ANIMAL KINGDOM.
         • such as
           • SILK
           • WOOL
           • COTTON
           • NATURAL RUBBER
           • THE DNA
     • SYNTHETIC
       • SYNTHETIC POLYMERS ARE MACROMOLECULES FORMED BY THE UNION OF MONOMERS, OBTAINED ARTIFICIALLY.
         • such as
           • POLYETHYLENE
             • Excellent thermal and chemical resistance. Very good impact resistance. It is solid, colorless, translucent, almost opaque.
           • POLYPROPYLENE
             • This has good rigidity, hardness and resistance, but minimal resistance. It has great resistance against various chemical solvents, as well as against alkalis and acids.
           • PVC
             • It is by far the plastic with the least dependence on oil. Its main property: a non-conductive electrical and thermal material, that is, a natural insulator.
           • POLYSTYRENE
             • It is used to make containers and various objects, whether in the form of foam or solid.
           • POLYACRYLONITRILE
             • It is a polymer used in the manufacture of synthetic fibers is used, for example, to make sweaters and fabric for tents.
           • PMM
             • It is one of the most transparent thermoplastics on the market, it perfectly resists blows and other strong impacts. It has great hardness, scratches easily.
           • NYLON
             • Mechanical resistance, hardness, rigidity and good toughness. Used in fishing lines and nets, zippers for textiles, synthetic strings for guitar, piano and other instruments.
           • CHLOROPRENE
             • Resists weather degradation; acceptable resistance to solvents and chemical agents; It is resistant to damage caused by bending and twisting.
