Why does the base of xenon lamp use PPS material?

The base of a xenon lamp typically uses PPS (Polyphenylene Sulfide) material for several important reasons: Resistance: PPS is known for its exceptional heat resistance. Xenon lamps generate a significant amount of heat during operation, and the base of the lamp is exposed to high temperatures. PPS can withstand these elevated temperatures without deforming, melting, or emitting harmful fumes. This heat resistance ensures the lamp’s stability and safety. Resistance: PPS is highly resistant to a wide range of chemicals, including automotive fluids like oils and coolants. This chemical resistance protects the base of the xenon lamp from corrosion and degradation, ensuring its long-term reliability in the harsh environment of an automotive engine bay. Insulation: PPS is an excellent electrical insulator. Since xenon lamps rely on electrical connections to operate, it’s crucial that the base material does not conduct electricity. PPS prevents electrical
