BC-440
Premium Plastic Scintillator
General Description
General Technical Data
The premium plastic scintillators BC-440, BC-440M, BC-448, and BC-448M are designed to withstand temperatures up to 99°C (150°C for those designated with "M").
| Base |
Polyvinyltoluene |
| Density |
1.03 g/cc |
| Refractive Index |
1.58 |
| Coefficient of Linear Expansion |
7.8 x 10-5, below 70°C |
| Solubility |
Soluble in aromatic solvents, chlorine, acetone, etc. Insoluble in water, dilute acids & alkalis, lower alcohols, silicone fluid, & grease. Scintillators with the "M" designation are more resistant to aromatic solvents, but some swelling of the base and leeching of the scintillation solutes are likely. |
