List of known existing polymers
Bioplastics (not necessarily well biodegradable)
- PLA … polylactic acid – made from biomatter
- PHA … polyhudroxyalkanoates – [1]
- CA … cellulose acetate
Elastic plastics
- TPU … thermoplastic polyurethane
Ultra low melting plastics
- PCL … low melting plastic used in medicine and early 3D printer prototypes
Water dissolvable plastics
- PVA … water soluble plastic related to non-toxic wood glue - petrol made but biodegradable
Acetone dissolvable plastic that stink when heated
- HIPS … cheap and brittle
- ABS … LEGO
- ASA … more UV resillient
Highly transparent plastics
- PMMA (aka plexiglass)
- PETG … (common bottleplastic)
Self lubricating / tough plastics
Cheap:
- HDPE … high density polyerhylene – detergent bottles
- LDPE … low density polyethylene – plastic bags
Less cheap:
- UHMWPE (dyneema) … [2] – ropes
- POM (delrin) … polyoxymethylene – plastic gears, lubricating spacess
- PA (nylon) … polyamides same backbone as natural proteins – lawnmower strings
- PC … polycarbonates [3]
- PTFE (teflon) … [4] – pan coatings, tubes
High performance polymers (typically include carbon rings)
- PEEK … e.g. used as heat-break in 3D printer hot ends
- PEKK
- PEI … polyetherimide – [5] e.g. used as 3D printer printbed coating
- used as 3D priner heatbed coating
- Aramid (kevlar) – https://en.wikipedia.org/wiki/Aramid
- Polyimide (kapton) – seen on spacecraft, UHV systems, 3D printer heatbeds
https://en.wikipedia.org/wiki/Kapton
Misc
- PVC … polyvinylchloride – troublesome when burnt thus faded out except for e.g. orange ground pipes
Polymers: Polycarbonates with small linkers like:
- PPC … polypropylene carbonate [6]
- PEC … polyethylene carbonate – rare but available commercially empowermaterials
- polymethylene carbonate??
Compositon wise this is almost polymerized carbon dioxide.
Could this be used as CO2 sink?
