What
is IRMRA? |
| Ans. |
IRMRA,
popularly known as Indian Rubber Manufacturers
Research Association, is an autonomous body
affiliated to Ministry of Commerce & Industry,
Govt. of India. |
| |
|
| 2. |
What
is its main activities? |
| Ans. |
Its
main activity can be divided into four areas
:-
1. Testing
2. Research & Consultancy
3. Training
4. Product Development.
|

|
| 3. |
Do
IRMRA have accreditation of ISO/BIS? |
| Ans. |
Yes,
IRMRA is accredited by ISO, BIS, DGMS and
defence organisation. |
| |
|
| 4. |
Is
the test certificate acceptable by Govt. Organisation? |
| Ans. |
Test
certificates are accepted by all Govt. agencies
and renowned Industry. |
| |
|
| 5. |
Who
can avail the facility of IRMRA? |
| Ans. |
Any
Industry dealing with rubber parts can avail
the facility on nominal charge basis. |
| |
|
| 6. |
We
are interested to know the type of rubber
in an unknown product :- can IRMRA test it? |
| Ans. |
Yes,
IRMRA can identify the type of rubber, both
by chemical and FTIR techniques. |
| |
|
| 7. |
What
is the limitation of Polymer identification
by Chemical testing over FTIR? |
| Ans. |
Chemical
testing cannot identify the blend of two rubbers
and also it is applicable mostly for VIRGIN
Polymer. |
| |
|
| 8. |
How
can we find out the carbon content in rubber
product? |
| Ans. |
We
can find out the carbon black filler content
in rubber product by Thermogravimetric Analyser
(TGA). Slow healing by programmed system degrade
the organic ingredients under Inert conditions.
But carbon degrade only undue oxygen/air atmosphere. |
| |
|
| 9. |
Can
it be possible to find the proportion of different
rubbers used in a product, if Yes, then how? |
| Ans. |
Different
rubber blend ration can also be determined
by TGA. But this need controlled heating and
special programme. |
| |
|
| 10. |
What
is oil resistance Rubber and why it is oil
resistance? |
| Ans. |
Nitrile,
VITON, Neoprene etc are oil resistance rubber.
Pressure of polar group in the monomer makes
these rubber oil resistances. |
