Revise: Thermosetting PolymersUrea formaldehyde (UF) is another thermosetting polymer. It is hard, rigid and heat resistant, with a smooth finish that is commonly white. It can be moulded into product shapes during manufacture, but cannot be remoulded after curing.
A hard, rigid thermosetting polymer with good electrical and thermal insulating properties.
Link a property to the product's needs: urea formaldehyde is an electrical insulator, so it helps prevent current passing through a socket casing to the user.
Link each property to the product’s needs: electrical insulation helps make urea formaldehyde suitable for a light-switch casing.
