What are all the types of plastic?

Question

Please, if you can, tell how each type of plastic looks like.

Answer 1

There are two basic types of plastic:

thermoplastic – can be repeatedly softened and remolded by heat and pressure (e.g. celluloid, lucite)

thermosetting – cannot be resoftened after being subjected to heat and pressure (e.g. bakelite)


They are broken down into 7 catagories for being recycled:

* Type 1 - PETE Polyethylene Terephthalate (PET)
Soda & water containers, some waterproof packaging.
* Type 2 - HDPE High-Density Polyethylene
Milk, detergent & oil bottles. Toys and plastic bags.
* Type 3 - V Vinyl/Polyvinyl Chloride (PVC)
Food wrap, vegetable oil bottles, blister packages.
* Type 4 - LDPE Low-Density Polyethylene
Many plastic bags. Shrink wrap, garment bags.
* Type 5 - PP Polypropylene
Refrigerated containers, some bags, most bottle tops,
some carpets, some food wrap.
* Type 6 - PS Polystyrene
Throwaway utensils, meat packing, protective packing.
* Type 7 - OTHER Usually layered or mixed plastic.
No recycling potential - must be landfilled.
Types 1 and 2 are commonly recycled. Type 4 is less commonly recycled. The other types are generally not recycled, except perhaps in small test programs. Common plastics polycarbonate (PC) and acrylonitrile-butadiene-styrene (ABS) do not have recycling numbers.
