Socket,also known as power socket,switch socket,English translation:Power socket refers to a seat that can be inserted by one or more circuit wiring,through which various wiring can be inserted to facilitate connection with other circuits.The power socket is an electrical device that provides a power interface for household appliances,and is also an electrical accessory that is used in residential electrical design.It has a close relationship with people's lives.

　　Material selection of the socket:During the use of the socket,due to the action of current or abnormal operation or malfunctioning lamp,it may cause higher temperature and even cause red heat of the charged metal,which requires the insulation material of the socket to be in a certain temperature condition.The lower part should not be deformed or softened,and the flame will not spread when the live parts are leaked or exposed to an open flame.Today's socket housings are typically made of thermoplastic factory plastic-polycarbonate plastic(PC).

　　PC is a kind of thermoplastic engineering plastic with excellent performance,with sudden air impact capability,good creep resistance and dimensional stability,low heat resistance,low water absorption,non-toxicity and good dielectric properties.It is among the five engineering plastics.The only product with good transparency is the fastest growing general engineering plastic in recent years.Therefore,the PC is an excellent choice for the material of the socket housing.Secondly,plastic power sockets have high requirements for additives and coloring materials.

　　Masterbatch,a simple understanding is a kind of pigment specially designed for plastics.The masterbatch is much higher than the pigment,that is,it can be colored and has certain effects,such as antistatic,anti-ultraviolet,flame retardant,etc.Because the masterbatch has a variety of color for PC plastic,the carrier of the masterbatch is also PC plastic.Therefore,it is the best choice for the power socket to use the masterbatch as the coloring.
