PP Diffuser Sheet

About this sheet

Yongshang PP diffuser sheet is extruded on our own lines in Henglan Town, Zhongshan, from 100% virgin polypropylene — no regrind and no fillers. It spreads LED output evenly across the panel, so hotspots, bright dots and dark corners disappear: the most common reason a finished fixture gets rejected at inspection.

The sheet is supplied from 0.3 mm to 2.0 mm as standard 1.22 × 2.44 m panels or rolls, with the surface finish and light transmittance matched to your light source. It is our highest-volume grade, used mainly in LED panel lights, suspended linear lights and surface-mount ceiling lights.

Where it is used

• LED panel lights
• Suspended linear lights
• Surface-mount ceiling lights
• Office and commercial lighting
• Edge-lit fixtures
• Furniture and emergency lights
