Case material - Plastic
As an important part of the uninterruptible power supply (UPS) equipment, the housing material not only needs to have good mechanical strength and durability, but also needs to have corrosion resistance, insulation and a certain degree of beauty. Among many materials, plastics are widely used because of their excellent performance and economy. This article will focus on several commonly used plastic materials: ABS, polypropylene and polyvinyl chloride.
Acrylonitrile-butadiene-styrene（ABS）
ABS plastic is a kind of engineering plastic widely used in the shell of electronic products. Its main components include acrylonitrile, butadiene and styrene, so it has a good comprehensive performance. Advantages of ABS include:
Excellent mechanical properties
ABS material has good impact resistance and toughness, can withstand a certain amount of external impact and pressure, and protect the internal circuit from damage.
Good processing performance
ABS can be processed by injection molding, extrusion molding and other ways, suitable for large-scale production.
Heat resistance
Although the heat resistance of ABS is relatively low, it can still maintain good performance within a certain range and adapt to the working environment of UPS equipment.
Easy surface treatment
ABS smooth surface, easy to spray, print and label, can provide a rich appearance choice, make the product more attractive to users.
Polypropylene (PP)
Polypropylene is a thermoplastic, because of its excellent chemical stability and corrosion resistance is widely used in a variety of equipment shell, especially in the field of UPS. The main features of polypropylene include:
Lightweight
The density of polypropylene is low, so that the overall weight of UPS equipment can be effectively reduced, easy to handle and install.
Excellent chemical resistance
polypropylene has good resistance to most chemicals and is not easy to be corroded, so it can still play a role in harsh environments.
High melting point
The melting point of polypropylene is high, so that it can maintain relatively stable performance in high temperature environment, suitable for long working occasions.
Good insulation performance
polypropylene is an excellent electrical insulation material, which can effectively protect the internal circuit and ensure the safety and reliability of the equipment.
Polyvinyl chloride (PVC)
Polyvinyl chloride is an economical and practical plastic material with good wear resistance and impact resistance. The application of PVC in the UPS housing is mainly based on the following aspects:
Corrosion resistance
PVC has excellent corrosion resistance to most acid and alkali salts, which can protect the normal operation of equipment in humid environment.
Better mechanical properties
PVC is also more prominent in impact and tensile performance, suitable for a variety of external environments.
Good fire resistance
PVC is a material with certain flame retardant properties, which helps to improve the safety of equipment and reduce the risk of fire.
Cost effectiveness
The production cost of polyvinyl chloride is relatively low, which can effectively reduce the overall production cost of UPS equipment, thereby enhancing the market competitiveness.
CONCLUSION
As the main choice of UPS housing material, plastic has a variety of excellent characteristics to meet the needs of different applications. ABS, polypropylene and polyvinyl chloride each have their own unique advantages that enable them to improve the service life and safety of products while protecting electronic devices. With the continuous progress of technology, the application of these plastic materials in electrical equipment such as UPS will be more and more extensive, becoming an important basis for achieving product lightweight, high performance and environmental friendliness.
