Insulated Fire Resistance PPS PP Solid Sheet Plastic Panel For Electrical Enclosure

PPS sheets (polyphenylene sulfide sheets) are a type of high-performance thermoplastic engineering plastic sheets with excellent comprehensive properties, and they have important applications in many high-end fields.​ PPS boards exhibit good processing adaptability in terms of shaping. Although they are high-performance engineering plastics with stable molecular structures, they can still be formed and processed through various processes such as injection molding, extrusion, and compression molding. They can accurately shape complex geometric shapes to meet the design requirements of different industrial components.

Core Advantage

PPS boards, which meet fire safety standards of Class B1 or higher, offer significant advantages when used for electronic device casings due to their fire resistance: they are difficult to burn when exposed to fire and release no toxic smoke. When an electronic device catches fire due to short circuits or overheated components, the casing made of fire-resistant PP boards can block the spread of flames, prevent the fire from expanding, reduce harm from toxic gases, and gain time for emergency treatment and personnel evacuation. Meanwhile, the internal parts of electronic devices such as chips and circuit boards are highly flammable.

Excellent Performance

In terms of performance, PPS sheets first exhibit strong high-temperature resistance. The long-term service temperature can be stably maintained at 200-240℃, and they can even withstand high temperatures above 260℃ in the short term, which enables them to maintain structural stability and mechanical properties in high-temperature environments, maintaining structural stability without softening or deformation under high temperatures. This ability to insulate against open flames and high-temperature baking helps reduce malfunctions like component burnout and circuit adhesion, thereby lowering equipment maintenance and replacement costs.

Application in Electrical Enclosure

In addition, electronic devices such as routers and power adapters need to pass certifications like UL and CE, where fire resistance is a key indicator; using fire-resistant PP boards to make casings allows these devices to easily meet the certification requirements, facilitating their entry into the market while conveying an image of "safety and reliability" to enhance market competitiveness. Moreover, electronic devices like server rooms and office equipment are often placed densely, resulting in limited space and concentrated heat dissipation, which easily leads to high-temperature risks. Fire-resistant PPS boards combine fire resistance with lightweight properties, so the casings made from them are thin and light without increasing the overall volume of the equipment, providing fire protection for densely placed devices and reducing the probability of chain fires.
