Neoprene rubber is a thermoset elastomer used for window seals, hoses, cable insulation and for gaskets.
There are various forms of neoprene available but they will all bond well with cyanoacrylates and a primer is not usually required (Table 4.9).
Polyisoprene is a thermoset elastomer and has high tensile properties and its main advantage over natural rubber is that it is generally easier to process. It is used for the manufacture of rubber bands, baby milk bottle teats, sporting goods and engine mounts.
Cyanoacrylates show good adhesion to polyisoprene and primers are not usually required (Table 4.10).
