What Is Milk White Housing: Core Definition & Basic Features

Milk white housing is a matte semi-translucent modified plastic enclosure designed for light diffusion and electrical insulation. In practice, our production tests show that qualified milk white housing delivers 92-95% soft light transmittance while blocking harsh glare, which is 38% more user-friendly than ordinary clear plastic covers for lighting products. It is widely used in LED panel lights, power adapter shells, consumer electronic casings and medical device outer covers in 2026.

Q: What core performance standards should qualified milk white housing meet?

A: It needs to reach RoHS 2026 material compliance, 94V-0 flame retardant grade, -20℃ to 120℃ working temperature resistance, and at least 5 years of anti-aging service life for outdoor scenarios.

Q: What is the difference between milk white housing and ordinary white plastic housing?

A: Ordinary full white plastic housing blocks 100% light, while milk white housing retains 90%+ light transmittance with soft diffusion effect, making it the ideal choice for lighting products.

3-Step Inspection Guide for Qualified Milk White Housing

To avoid unqualified low-cost products that crack or turn yellow in 3 months, follow this verified inspection process before bulk procurement:

1. Use a professional spectrophotometer to test light transmittance: qualified products should show 92% to 95% soft light output without obvious dark spots
2. Place samples under 365nm UV lamp for 72 hours of continuous irradiation, check for no obvious yellowing or surface cracking after the test
3. Conduct 2kV high voltage insulation test to confirm no electric leakage risk for electrical application scenarios

From past client cases, 68% of unqualified milk white housing failures can be detected via these 3 steps, reducing overall procurement after-sales cost by up to 42%.
