C200 Encapsulation Polyurethane

The C200 Encapsulating Rubber which we use for moulding cable splices and overmoulding connector housings etc. is a polyetherurethane rubber. This particular material is heat cured with a diamine based compound to form a polyetherurethane rubber with outstanding physical properties.

C200 should not be confused with cold setting and hot setting polyester based urethanes, since these materials have vastly inferior water resistant properties.

The C200 rubber has excellent water and oil resistant properties. The long term water resistance has been tested over a 10 year period, and the results show the material does not appreciably degrade (See  table below). We have practical knowledge of the successful use of C200 in subsea applications over the past 25 years. The Hydro Group specialize in chemically bonding the C200 rubber to metals and other elastomers. We can bond to most conventional cable sheath materials e.g. Neoprene, Hydrel, Nitrile, Polyurethane, Hypalon, EPR etc.

Working temperature range: +100 deg. C. to -70 deg. C. Specific gravity: 1.1
