General Data |
|
Rexon Plastic Scintillators |
|
| |
|
|
| |
Base:
Polyvinyl toluene |
|
Plastic
Scintillators offer high performance, ease of handling, mechanical
stability at a relatively low cost. The versatility of plastic
Scintillators makes them the ideal choice for large area and specially
shaped detectors.

The
plastic scintillators are soluble in aromatic solvents,
acetone, chlorinated solvents etc. They are unaffected by water,
dilute acids, alkalis, lower alcohols, pure methyl, silicone
grease or
fluid. |
