what are thermosetting polymers used for
Recycling of thermosetting polymers: Their blends and composites 125 Phenol-formaldehyde mouldings are widely used for domestic plugs and switches. Used in electrical industry where high electrical insulation properties are not needed. It is used for making cases, knobs, handles and telephones.lso, used in data processing equipment such as pressure discs, sleeves, bearings, and as friction elements. They are also used as valve shafts in shut-off values. Due to the heat resistance capacity and deformation resistance of the polymers, they are used in soldering and welding equipment.
