Apr 25, 2019· Long chains of monomers are polymersEthylene becomes polyethylene, propylene becomes polypropylene, styrene becomes polystyrene, etcA polymer comprised of only one monomer is known as a homopolymerA polymer with two monomers ,
Polymerization: How Plastic Materials are Made - Craftech ,
Bailey – We don’t make plastic at Craftech, we machine it and use it in injection molding I’m sure the waste products vary greatly, depending on the specific material There are many dozens of materials, each with a different formulation and process You might get a better answer from a plastic resin manufacturer Good luck!
A plastic is a polymer, which is made of a long chain of monomers The monomers that constitute plastics can be natural or synthetic Find out some interesting facts about plastics and how they are made, through this Buzzle article
monomers is used to manufacture each different type or family of polymers There are many polymers , Plastic recycling is an important process for reducing waste and recovering potentially valuable raw materials, for example, it has been possible to buy fleece clothing
