Advantages of PP plastic balls in electrical insulation

1. Low dielectric constant ensures good electrical insulation
One of the major advantages of PP plastic balls in the field of electrical insulation is its low dielectric constant. Dielectric constant is an indicator of the ability of a material to conduct current in an electric field. A low dielectric constant indicates that the material can effectively isolate the conduction of current and play a good electrical insulation role. For electrical equipment, good electrical insulation is essential to prevent the occurrence of safety hazards such as current leakage and short circuit.

The dielectric constant of PP is usually between 2.2 and 2.3, which is relatively low, which enables it to provide good insulation performance in high-frequency electric fields. Therefore, PP plastic balls are widely used in electrical equipment that requires insulation, especially in liquid level monitoring equipment that requires floating indication or control, which can ensure the safe and stable operation of the electrical system.

2. Excellent temperature resistance ensures long-term use
PP plastic balls have a high melting point, usually around 160°C, which is much higher than common thermoplastics. Due to the high melting point, PP plastic balls can maintain stable electrical insulation in high temperature environments, which enables them to still function in high temperature working environments. In the application of electrical equipment, especially in liquid level sensors or switches used in high temperature environments, PP plastic balls can ensure long-term stable operation without losing insulation due to temperature increase.

3. Chemical resistance enhances the stability of electrical systems
Plastic materials used in electrical equipment must have good chemical resistance to ensure that their electrical performance is not affected when exposed to various chemicals. PP plastic balls have chemical resistance and can resist corrosion from a variety of chemicals such as acids, alkalis, alcohols, greases, solvents, etc. Many electrical equipment may be exposed to chemical corrosion environments during operation, especially in liquid level monitoring systems, which often need to contact liquids containing various chemical components.

PP plastic balls can resist the influence of these corrosive substances, maintain stable electrical insulation, and will not cause material performance to deteriorate due to changes in the external environment. For example, in liquid level sensors in the chemical industry, PP plastic balls not only need to float, but also need to maintain electrical isolation functions. When facing chemicals, its corrosion resistance can effectively ensure the long-term operation of the system.

4. Reduce equipment weight and improve operational safety
In electrical equipment, especially liquid level control equipment, floating elements are often required to indicate liquid level changes. PP plastic balls have a low density and are lightweight, which significantly reduces the overall weight of the equipment. This lightweight design not only facilitates the installation and operation of the equipment, but also reduces the mechanical burden and the failure rate. In some precision electrical devices, reducing weight helps improve the stability and response speed of the equipment, while also reducing wear and tear during long-term use.

In electrical insulation applications, the lightness of PP plastic balls makes it an ideal choice. For example, in electrical equipment that requires frequent operation and movement, the use of lightweight PP plastic balls can improve the operational safety of the equipment and avoid mechanical damage caused by excessive weight of the equipment.

5. Wide range of applications
Due to its electrical insulation, PP plastic balls have been widely used in many fields. Typical applications include liquid level control systems, float switches, liquid level sensors, etc. Especially in medical equipment, chemical industry, and food and beverage industry, PP plastic balls can not only provide accurate liquid level indication, but also effectively isolate current and ensure the safety of equipment. In these application scenarios, the importance of PP plastic balls as insulating materials cannot be ignored.
