Transcription

1 Guangdong Grandview Material Limited Acrylic (PMMA) Sheets have these features: SIZES virtually unbreakable weather resistant UV coated & desert tested shatter - proof thermoformable having safe fire performance light weight durable and elegant surface finish suitable for interior & exterior application ideal for privacy glazing, roof lights & shower doors Width: 1220 to 2050 mm (Standard) Length : 2440 to 3050 mm (Standard) Thickness : 1.5 mm to 30 mm Other widths and lengths available on request. COLOURS Clear, White, Opaque, Blue, Red, Black and many more! CHARACTERISTICS OF Beauty-Intl ACRYLIC SHEETS light in weight ACRYLIC (PMMA) SHEETS Acrylic (specific gravity 1.2) is less than half of the weight of inorganic glass (specific gravity 2.5). Weather-Resistance Acrylic has an extremely excellent resistance to sunlight, weather, and both high and low temperatures. Outdoor exposure test for all kinds of acrylics has been done both in desert and in laboratory. Various Colors Available A wide range of transparent colors as well as translucent colors are available. Surface of colored sheet has superior gloss. White translucent colors have a superior light

2 diffusion effect, characteristics of which are made good use in lighting diffuser panel, sky-light dome, sign board and so on. Impact Resistance Acrylic has greater impact strength than glass. It is unbreakable and even in the case of breakage it will be safe because it doesn't become small pieces which fly off to the different directions like glass. Easy Formability Being a thermoplastic, Acrylic becomes soft when heated, and hard when cooled. Surface Hardness The surface hardness of Acrylic is almost the same as that of aluminum. It is harder than some of other plastics sheet but softer than glass. Chemical Resistance It is insolvent to inorganic chemicals and normal chained hydrocarbon, but contact with organic solvents causes dissolvent, swelling, hazing and cracking.
