Teflon has fluorine attached to the all-carbon backbone. You guessed it – if there is another conjoined monomer (not a mechanical blend), you got a CO polymer. Examples: “ethylene vinyl acetate” or EVA for short – vinyl acetate monomer married to ethylene monomer, “styrene butadiene styrene” or SBS – styrene and butadiene building blocks, A very cool copolyester is Eastman’s Tritan. Metallized plastics are used to replace metal objects by plastics for example to reduce the weight of a product of both the conductive metal and the insulating plastic form a functional unit as in the case of a printed circuit board or film. Since metals generally bond poorly to polymers, the plastic surface has to be treated. 1 Source: Plastics Europe, Association of Plastics Manufacturers, World Thermoplastics Demand by Types 2015.

Polymers and plastics: what’s the difference? Although the words ‘polymer’ and ‘plastic’ are often used interchangeably, plastics are actually just one kind of polymer. They’re polymers that have plasticity. In other words, they can be moulded—using heat, for example. Nitrogen data of plastics additives. Table 4.

Examples include fiber reinforced plastics (FRPs), sheet molding compounds (SMCs), bulk molding compounds (BMCs), pre-preg materials, and fabricated composite parts. Plastics and natural materials such as rubber or cellulose are composed of very large molecules called polymers. Polymers are constructed from relatively small molecular fragments known as monomers that are joined together.
