2. Plastic - Wikipedia

   en.wikipedia.org/wiki/Plastic

   The rest was pre-consumer waste from resin production and manufacturing of plastic products (e.g. materials rejected due to unsuitable color, hardness, or processing characteristics). [ 2 ] The Ocean Conservancy reported that China, Indonesia, Philippines, Thailand, and Vietnam dump more plastic into the sea than all other countries combined ...

3. Polyethylene - Wikipedia

   en.wikipedia.org/wiki/Polyethylene

   Since 2008, Japan has increased plastic recycling, but still has a large amount of plastic wrapping which goes to waste. Plastic recycling in Japan is a potential US$90 billion market. [26] It is possible to rapidly convert polyethylene to hydrogen and graphene by heating. The energy needed is much less than for producing hydrogen by electrolysis.

4. Polycarbonate - Wikipedia

   en.wikipedia.org/wiki/Polycarbonate

   The characteristics of polycarbonate compare to those of polymethyl methacrylate (PMMA, acrylic), but polycarbonate is stronger and will hold up longer to extreme temperature. Thermally processed material is usually totally amorphous, [7] and as a result is highly transparent to visible light, with better light transmission than many kinds of ...

5. High-density polyethylene - Wikipedia

   en.wikipedia.org/wiki/High-density_polyethylene

   HDPE is known for its high strength-to-density ratio. [4] The density of HDPE ranges from 930 to 970 kg/m 3. [5] Although the density of HDPE is only marginally higher than that of low-density polyethylene, HDPE has little branching, giving it stronger intermolecular forces and tensile strength (38 MPa versus 21 MPa) than LDPE. [6]

6. Polypropylene - Wikipedia

   en.wikipedia.org/wiki/Polypropylene

   Its properties are similar to polyethylene, but it is slightly harder and more heat-resistant. It is a white, mechanically rugged material and has a high chemical resistance. [1] Polypropylene is the second-most widely produced commodity plastic (after polyethylene).

7. Ultra-high-molecular-weight polyethylene - Wikipedia

   en.wikipedia.org/wiki/Ultra-high-molecular...

   This results in a very tough material, with the highest impact strength of any thermoplastic presently made. [2] UHMWPE is odorless, tasteless, and nontoxic. [3] It embodies all the characteristics of high-density polyethylene (HDPE) with the added traits of being resistant to concentrated acids and alkalis, as well as numerous organic solvents ...
