acrylic Pmma and PC PS board Difference
How to distinguish plexiglass, PC, PS properties and uses
1 .. plexiglass (acrylic) plexiglass name: polymethyl methacrylate (PMMA), English name Acrylics: some people called acrylic. There are excellent light performance, more than 92% by sunlight, ultraviolet up 73.5%; higher mechanical strength, a certain degree of heat cold resistance, corrosion resistance, good insulation properties, dimensional stability, easy to shape, texture brittle, soluble in organic solvent, a surface hardness is not enough, easy to wipe hair, may require a transparent structure for a certain intensity at which some additives may be added to improve its performance, such as heat, abrasion and the like. At present, the material widely used in advertising light boxes, advertising display display supplies, furniture supplies, hotel supplies, sanitary,,,,,.2 .. Yu Yu Yang Yang PC board PC sun panels (also known as polycarbonate hollow sheet, plate glass Capron, PC monolayer or multilayer hollow plate, polycarbonate plate) is a high-performance engineering plastics - --- polycarbonate (PC) resin processing, with high transparency, light weight, impact resistance, noise insulation, flame retardant, anti-aging, etc., but not acid, alkali not, is a high-tech , extremely excellent overall performance, energy saving plastic sheet
3.PS organic board, the chemical name (polystyrene) English chemical name (PS). Plexiglass plate features:
(1) It is a clear plastic sheet before, its high transparency (to replace the glass), can reach more than 89% transparency. Hardness in general.
(2) glossy surfaces in general.
(3) processing performance in general, suitable for mechanical processing and easily bending shape, suitable for screen printing and laser engraving. At present, the material widely used in advertising light boxes, advertising display display supplies. But the effect is worse than the acrylic currently on the market is the most popular plastic sheet: plexiglass panels, PC, PS, these types of plates are very like, in the same color contrast, basically unable to identify what those boards. If consumers do not understand the product knowledge, then it will bring opportunities to deceive the seller. So that the seller will be profitable. Assuming the current plates are full of these types of transparent and colorless, so the consumer can identify to which are colorless and transparent, but can not identify who is plexiglass (acrylic), those are PC sheet and so on. Is because it makes some unscrupulous businessmen will cheat some customers, with PS plate to act as plexiglass (acrylic), to act as a PC sheet with plexiglass!
1>plexiglass (acrylic) were: extruded sheet and cast plate recognition extruded sheet is transparency, with the most primitive method of identification, fire burning, burning flame clear, no smoke, bubbles, fire when you can pull out the filament. Recognition casting board are: greater transparency, when the fire burning, smoke-free, there is a bubble, there are creak, no wire when fire.
2>PC board identification methods are: high transparency, good impact resistance, playing not bad, with a fire burning is the basic burning vain, flame and black smoke will emerge part.
3>PS organic board, identification methods are: transparency in general, when there will be pitting reflective look. Relatively brittle, easily broken. Kaka hit the ground there will be sound. Will generate a lot of black smoke when the fire burning. The above example are described sheet is transparent and colorless. Performance of these three materials, the use of the processing are not the same. And their cost is not the same.
