RGC 749 consists of a foamed mixture of chloroprene rubber and cork.
Due to its structure, this material – which is resistant to oils and
fatigue – features high compressibility combined with dimensional
stability and extremely high recovery.
For gaskets and pads with very low sealing pressure, e.g. to seal
switchgear and air conditioning units.
for sealing against spray water
resistance to ozone and humidity
0.5 - 0.6
Compressibility and recovery acc. to ASTM F 36, procedure B
30 - 45
Minimum surface pressure
Short-term peak temperature
Maximum continuous temperature
Maximum internal pressure
Max. continuous temperature and max. pressure must not occur simultaneously.
RGC 749 complies with ASTM F 104, Identification F 229 000 M9
The data quoted above are valid for the material "as delivered" without
any additional treatment. In view of the countless possible
installation and operating conditions, definitive conclusions cannot be
drawn for all applications regarding the behaviour in a sealed joint.
Therefore, we do not give any warranty for technical data, as they do
not represent assured characteristics. If you have any doubt, please
