Lighting polystyrene is produced by extrusion of high impact polystyrene and all-purpose polystyrene. Designed specifically for illuminated advertising, it brilliantly replaces acrylic glass in the manufacture of any construction with internal illumination. Externally it is identical to the white acrylic glass, but has, in contrast to plexiglass, only one glossy surface (outer). Lighting polystyrene has a higher light diffusion index and shock resistance index compared to the acrylic sheet. It is easy to process and the cost of processing is significantly less than that of other plastic sheets. It is an excellent insulator.
Lighting polystyrene has a high chemical resistance to the diluted organic acids and solutions of alkalis, as well as to alcohols. Polystyrene is not resistant to organic solvents, such as gasoline, ketones (acetone), benzene, chlorinated hydrocarbons, ethereal oils, and greases.
Easily molded and can be processed by any mechanical tool, either for wood or metal processing. Agglutination (solvent-based adhesives such as toluene, methylene chloride, butyl acetate).
Welding (thermal, thermal impulse, ultrasound).
Lighting polystyrene is used for the manufacture of light diffusers and light-boxes, illuminated signs, billboards, etc. Contact paper with printed image or text can be sticked on the products made of lighting polystyrene without damaging the illumination and overall design of the entire advertising, because the brightness and clarity of the image are preserved.
LIGHTING PLASTIC SHEET FEATURES
Lighting plastic sheet combines a good impact resistance, resistance to mechanical damage, excellent molding capacity and easiness in processing. Surface of sheets can be glossy smooth or embossed. Making sheets by extrusion method gives the ability to connect two layers: the top layer of all-purpose polystyrene with a glossy surface; the lower layer is shock-resistant polystyrene with various levels of light radiation. Such sheet is UV-stabilized. A thermoformable protective film is put on a sheet, to maintain the quality of the glossy surface during transportation and processing. Then this film can be easily removed from the sheet and moulded parts.
