This table lists the monomers for several major plastics, as well as the properties and uses of each type of plastic. CHEMICAL NAME FORMULA PROPERTIES USES High weathering resistance. Weather-resistant with good chemical properties. Depending on their. Shore hardness, thermoplastic elasto This type of plastic material does not have a sharp melting point, but softens to a melt over a broad range of temperature. It, therefore, can be molded or The three-part classification of polymers that we have just looked at gives us an insight into the history of their use. Naturally occurring plastic materials. Their most common structure are linear A–B–A block type: styrene-butadiene-styrene (SBS), styrene-isoprene- styrene (SIS), styrene-ethylene/butylenes-styrene ( The seven types of plastics are Polyethylene Terephthalate (PET or PETE or Polyester), High-Density Polyethylene (HDPE), Polyvinyl Chloride (PVC), Low-Density This guide provides a basic outline of the different plastic types associated with each code number. Polyethylene Terephthalate sometimes absorbs odours and. These plastics do not undergo any changes in their chemical structures and chemical compositions when subjected to heat and can be changed into a soft state and
