RGC 749 consists of a foamed mixture of chloroprene rubber and cork.
Properties
Due to its structure, this material – which is resistant to oils and
fatigue – features high compressibility combined with dimensional
stability and extremely high recovery.
Application
For gaskets and pads with very low sealing pressure, e.g. to seal
switchgear and air conditioning units.
for sealing against spray water
excellent
resistance to ozone and humidity
