Specifications
Thermoforming is a manufacturing process where a plastic sheet is heated to a pliable forming temperature, formed to a specific shape in a mold, and trimmed to create a usable product. Our acrylic sheet is a kind of thermoforming plastic, which can be easily vacuum forming or blow molding, it's special designed for Led ceiling light cover, included round vacuum-forming cover or circline vacuum-forming cover and so on. To meet the different light transmittance and diffusion demands, there are several distinct thermoforming acrylic sheet available.
Description:
J.K 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.
Specification:
Length: Made as customer's demand
Width: 900mm-1350mm
Thickness: 1.8mm, 2mm, 2.2mm, 2.5mm, 3mm
For small size, saw cutting service is available.
Character:
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.
