because when electricity pass through the plug ,it produces heat and this type of plastic doesn't melt
Nylon is very popular for this application.
Plastic
Answer for UK Electrical SystemThe terminals of British electrical socket outlets are protected by shutters that are opened by the earth pin of the inserted plug. Many British electrical engineers believe that so-called 'child proof' socket protectors are unnecessary and, in fact, may actually be dangerous. These protectors are held in place by a plastic 'earth terminal' which, if inserted upside down, will actually open the shutters, making the terminals accessible to children's prying fingers. So, the general consensus is that these socket protectors should NOT be used.
