The outer sheath of the power cord plays an important role for the power cord. A good outer sheath can reduce the influence of the external environment on the current and make the power cord work normally. At present, the outer sheath of the power cord in our country is generally made of plastic, but the plastic does not have very good functions, and various chemical agents need to be added to the plastic. So what chemical agents are added to common plastic outer sheaths?

　　1 antioxidant

　　 Antioxidants can effectively prevent the oxygen atoms from eroding the unsaturated double bonds in the plastic, thus affecting the function of the outer sheath of the power cord. The use of antioxidants is the most common. It can prevent the oxidation of the outer sheath, thereby reducing its quality and shortening its life.

　　2. Antistatic agent

　　The harm of static electricity to plastics is very serious. Fires in many places are largely related to the static electricity attached to the product. Accumulation of static electricity will cause various accidents, such as electric shock accidents, fire accidents, etc. The treatment of static electricity in the plastic outer sheath is to add an antistatic agent to the plastic. It can effectively prevent static electricity from damaging the power cord, thereby increasing the ability to resist static electricity and reducing the probability of various accidents.

　　 3. Fire retardant

　　The addition of protective agent is the most chemical additive, which prevents the power cord from catching fire. Adding fire retardants to power cords has been a common practice in recent years. Because the power cord is always directly related to the occurrence of fire, the addition of fire retardant reduces the formation of fire and provides a certain guarantee for people's lives.

　　 The above three chemical additives are products that are often added to the outer sheath of the power cord, which can greatly improve the various functions of the power cord.
