No, it is thermoplastic as it can be re-heated and re-shaped.
If it has the recycled number on the bottom (probably code 2 HDPE) it is definately thermoplastic. One characterisitics of thermoplastics is that they can melt and be remoulded whereas thermosetting plastics can not (they will char). Therefore, it logically follows that if it can be recycled it will be a thermoplastic polymer.
HDPE= High-density polyethylene
thermosetting plastic
Thermosetting
Sometimes
the opposite to thermosetting plastic is thermoplastic
High Density Polyethylene (HDPE)
LDPE is softest, HDPE is harder, PMMA is much harder than HDPE
HDpe not soluble in any solvent at room temprture
Thermosetting plastics can not be recycled because they can not be reformed or re moulded
Thermosetting materials fuse under heat. The change is usually permanent.
