Seller: pmma_glass (1,933) 97.5%, Location: Milton Keynes, Ships to: GB, Item: 112321867585 Extruded organic glass. The material is characterized by long-term resistance to weathering, good impact resistance, light weight. The material is resistant to UV radiation. Plexiglas is easy to process and can be subjected to bonding, sawing, drilling, thermoforming. Technical specifications: - density - 1.19 g/cm3 - light transmittance (for transparent acrylic glass) - 92% - expandability - 0.065 mm/m/°C - maximal operational temperature - 85°C Polymethylmethacrylate - Acrylic sheets- Excellent transparency, with a 92% light- Suitable for decoration transmission- They can be moulded- Bright and colourless- Intermediate mechanical strength- High rigidity- The surface is suitable for buffing- Good insulation with high electrostatic- They are resistant to non-polar solvents charges (oils and aliphatic hydrocarbons)- Resistant to outside weather- Apt for contact with foodstuffs- Elevated hardness Properties Dimensional stability to heat:Prolonged exposure to heat must not exceed 80ºC Cracking under pressure:The appearance of cracking essentially depends on the joint action of a chemical agent, temperature, applied stress and the time during which these are applied. Ageing:Sheets show excellent stability to outside weather conditions, including UV radiation. Even after years of exposure to sunlight, the sheets do not show any substantial variations in their properties. When used in exterior applications, the protective film must be removed immediately, since exposure to sunlight can cause permanent adhesion to the sheet. HandlingCleaning:A solution of water and neutral detergent may be employed. They should always be cleaned and dried with a soft cloth with very little pressure.Cutting:Important! Do not remove the protective film from the sheets before cutting, and once this has been accomplished, blowing or suction should be employed to eliminate any chips.Manual cutting:Cutting should always be carried out with a fine-blade saw, with the sheet firmly held in place to prevent vibration. The teeth should be well-sharpened.Cutting with a blade: When cutting with a blade, this should be passed several times in order to achieve the desired depth (this should be a minimum of half the thickness), employing a uniform pressure. The sheet must be firmly secured to prevent sliding. Afterwards, the sheet should be placed on a flat surface and gentle pressure applied until it breaks. Sandpaper may be employed to eliminate any burrs. Sawing Cutting:Recommendations for PMMA sheets:- Disc diameter: 350 - 400 mm- Number of teeth: 84 - 106- Rotation speed: 2,800 - 4,500 rpm- Advance speed: 12 - 18 m/minType of teeth:Alternate teeth or combined straight and trapezoid. The sheet must be firmly secured to prevent them rising up and causing cracks when the disc passes. The translation speed should be as uniform as possible. The disc must be regularly sharpened. PolishingPMMA sheets can be polished using a mechanical buffer at a speed of 1,500 rpm and avoiding surface over-heating. Polishing requires a balance between rotation speed and applied pressure. Final polishing is achieved with soft cloth or flannel discs at high speed (4,000 rpm), with buffing paste. Edges may be polished using a high temperature air jet (200 to 300ºC) or by use of a flame. Drilling Metal and wood drill bits may be employed. The larger the diameter, the lower the speed. Water or air can be used for cooling. Aholediameterthatisapproximately1.5mm larger than that of the screw to be used should be drilled in order to take sheet dilation in to account. The sheet must be firmly secured to prevent breaking. Recommended drill speeds:Diameter (mm) / rpm:- 1.6 / 7.000- 5.4 / 1.800- 12.7 / 900 GluingPMMA sheets can be glued together to form a transparent joint. Depending on the application and surfaces to be glued together, various types of glue available on the market and suitable for methacrylate sheets can be employed, such as those containing dichloromethane.The following should be taken into consideration when selecting an adhesive:- Chemical compatibility with the sheets- Aesthetics of the finished joint- Dilation and contraction with temperature changes- Fragility, rigidity and flexibility- Alterability with respect to outside weather conditions, where applicable- Duration and useful lifetime- Adhesive strength (adherence to the plastic)- Final usage requirements Important! To prevent air bubbles, the glue should be allowed to stand for a while before application, until none can be seen. It is recommended that: The surfaces to be glued are clean and degreased. The glued parts must be allowed to dry for twenty-four hours so that maximum hardness is achieved. Thermoforming PMMA sheets are easily thermoformable in any oven with air circulation. The sheet temperature must exceed 140ºC. If the sheets have been stored in a damp environment, it is preferable for them to be previously dried for a few hours (two to four) at an approximate temperature of between 80 to 85ºC in order to avoid thermoforming problems. To achieve a good finish, the mould employed can also be heated to between 50 and 60ºC. An excessive mould temperature could harm the sheets. The protective film is not prepared to withstand high temperatures and must be removed prior to thermoforming or hot-bending. Bending PMMA sheet bending requires a bending template, together with a heating element or incandescent wire. The area to be bent must be completely and uniformly heated. We recommend that the smallest radius be twice the sheet thickness. It is a good idea to cool the part of the sheet that is closest to the bending line. The protective film is not prepared to withstand high temperatures and must be removed prior to thermoforming or hot-bending. Decoration Silk-screening:PMMA sheets can be silk-screened just like other materials. Acrylic-based and two-component inks are recommended: epoxy or polyurethane.Painting:They can also be painted by normal spray methods. No prior surface treatment is necessary, apart from cleaning. The paint that is employed must be specially indicated by the manufacturer as suitable for use on methyl polymethacrylate. In general, it is recommended that they contain an acrylic resin base with lowaggressivity solvents. They can also be vacuum metallised. The print film should be removed just prior to printing to prevent the surface from damage. Condition: New, Brand: Unbranded/Generic, Modified Item: No, MPN: Does Not Apply, Non-Domestic Product: No
