thermoforming acrylic sheet is kind of extruded product, which combine PMMA resign and different scale of diffusion agent, features distinct high light diffusion and high light transmission. It’s kind of translucent milk white material, which one side is matte, another side looks like orange peel texture. It’s an idea lampshade material for LED ceiling light.
Length: Made as customer's demand
Thickness: 1.8mm, 2mm, 2.2mm, 2.5mm, 3mmFor small size, saw cutting service is available.
Light weight, weather resistance ( at least 5 years ), good light efficiency, light transmittance can be 80%-90% after forming to lampshade, and light is uniform and soft.
