Burning
Test
|
|||
| 1 | NITRILE (NBR) |
:
|
It burns with sooty flame leaving untolerable smell. |
| 2 | EPDM |
:
|
Burns readily with sooty flame leaving dry and waxy odour. |
| 3 | BUTYL (IIR) |
:
|
Burns readily with phenolic odour and if colour tested with pyrolysate, it will give positive test. |
| 4 | NEOPRENE (CR) |
:
|
It burns with sparkling flame with HCL odour and if tested with copper (Heat the copper and touch to the sample) the flame will grow green. |
| 5 | FLUOROCARBON (FPM) |
:
|
It burns and leaves acrid HF odour and it can be easily found out of his high density than other rubber |
| 6 | NATURAL RUBBER (NR) |
:
|
It burns continuously and become sticky and give Black Path to the holding portion. |
| 7 | POLYURETHENE (AU.EU) |
:
|
It burns and melts leaving drops continuously. |
| 8 | SILICONE (Q.MO.MVQ) |
:
|
It burns with white flame and giving white smoke. (No other rubber give white smoke) & smelling Bitter Almond. |
