Power Supply Housing PC Plastic

Power supply housings for adapters, chargers and smart plugs operate under continuous electrical load and rising internal temperatures, while buyers expect the enclosure itself to resist ignition and surface tracking. Power Supply Housing PC Plastic is a halogen-free, flame-retardant polycarbonate compound developed for these low-voltage power enclosures. Its formulation is built around three electrical-safety properties commonly demanded by housing makers: a UL94 V-0 flame-retardant performance, a high Glow Wire Ignition Temperature of 775 degrees Celsius and above, and a high Comparative Tracking Index grade. The high GWIT allows the housing to resist ignition when it is exposed to abnormal heat sources or glowing components inside the enclosure, which matters for adapters and chargers that can overheat under fault conditions. The high CTI helps the part keep reliable electrical insulation and lowers the risk of surface tracking when the housing sits in humid or dusty operating environments. The polycarbonate matrix underneath also brings inherent toughness and rigidity, so thin-wall adapter shells can protect the internal PCB and transformer against drops and assembly stress without cracking. The compound is designed to fill thin, ribbed housing geometry and release cleanly from the mold, which keeps the wall sections thin enough for heat dissipation while remaining easy to process on standard injection equipment. Because the retardant system is halogen-free, the material aligns with the restricted-substance direction that many downstream power-supply brands now require for consumer and industrial adapters, and it avoids the corrosion and handling concerns that older halogenated systems carried.

For housing producers, the practical benefit is that the flame-retardant performance, the GWIT level and the insulation behavior are tuned as one balanced package rather than added onto a general-purpose PC. We adjust the halogen-free system, the GWIT level and the CTI grade together against your target wall thickness and certification route, which helps cut re-test loops and supports electrical-safety compliance starting at the tooling stage. Our R&D team works from your technical drawings or sample parts, and samples of 5KG or less are available for tooling trials before bulk release, so you can confirm flow, surface and dimensional behavior on your own mold before committing to a full order.

Power adapter housing

V-0 flame retardancy and a high GWIT protect the shell against internal heat and glowing components, which is the core failure mode in an overheating adapter.

Charger housing

The high CTI insulation grade maintains tracking resistance under load and humidity, keeping the plastic barrier safe around live contacts.

Smart plug and socket housing

The halogen-free system meets restricted-substance requirements while thin-wall toughness protects internal electronics during plugging and drops.
