Plug covers provide protection against hazards such as electrical shock that result from uncovered electrical outlets. In addition, plug covers protect the electrical outlets from environmental hazards such as water, heat, and cold weather.
As a result, plug covers are extremely useful in industries such as chemical and food processing, industrial, telecommunications, marine, military, commercial, and residential, where they are widely used for infant safety.
Plug covers are electrical outlet coverings. Many industries require plug covers, especially industrial manufacturers, due to the concern for employee safety as well as the frequent use of chemicals and other corrosive agents.
In response to harsh environments, plug covers are typically made from materials that are highly corrosion-resistant. Additional features such as thermal stability and temperature resistance may also be provided depending on the material used, and at this point, the plug covers become much more application-specific.
Not only functional and necessary equipment, plug covers may also be aesthetically pleasing, as they are available in a wide range of colors and designs ranging from plain and basic to the highly complex.
Since plug covers are typically designed based on a specific application’s requirements, there is a wide range of materials that are used based on their various characteristics. Some common materials that are used to make plug covers include stainless steel, aluminum, ethyl vinyl acetate (EVA), polyethylene (PE), and polypropylene (PP).
As a popular industrial metal, aluminum is used for plug covers because it has both good electrical and thermal conductivity as well as being highly oxidation-resistant.
A thermoplastic elastomer, EVA is used for plug covers because it is extremely resistant to cracking and able to retain flexibility at low temperatures.
Another popular industrial metal, stainless steel is used to make plug covers because it has high corrosion and chemical resistance.
As a common industrial thermoplastic, PE offers excellent electrical properties but has poor temperature resistance.
Lastly, PP has the unique characteristics of outstanding bi-axial strength as well as cold flow and yield elongation properties.
Much less common materials such as natural rubber and styrene butadiene (SBR) may be used for applications requiring unique attributes such as an increased resistance to certain chemicals like oils or hydrocarbons.
