Polymethyl methacrylate is one of the most famous and well-known polymers that was used in the beginning as a substitute for glass with various applications and today it is widely used in window and glass industries. Acrylic sheets with high dimensional stability, heat resistance, transparent and polished surface, low scratching percentage of high exposure, is a suitable alternative to glass. It is interesting to know that polymethyl methacrylate sheets are also widely used in the preparation and construction of aircraft windows. Yazd Golden Polymer Company, using the latest machines and advanced technologies in the world, has started to produce polymethyl methacrylate flat plates according to DIN EN ISO 7823-2 standards.
Polymethyl methacrylate sheets have significant resistance to weathering and sunlight. They have excellent optical properties and a clear surface, and at the same time are more impact-resistant than glass. In addition, they have a very low moisture absorption percentage and good tensile and electrical resistance.
About 40 to 50 percent of the polymer's products are used in the automotive industry, 33 percent in the construction and lighting industries, and the rest in the production and design of CDs, toys, stationery such as pens, decorations and statues, and the electrical industry.
Polymethyl methacrylate bed sheets made by Yazd Golden Polymer Company have many domestic, commercial, industrial and professional uses and therefore are considered as versatile and adaptable materials. Its main applications include the following groups:
Construction: Optical and skylights, partitions, window glass, roofing materials, skylights, safety and security glass, bathroom and kitchen glass, unbreakable glass, office equipment
Lighting and lighting: indoor lighting components, lighting control lenses, lens, lamp cover
Industry: Safety chambers and coatings for workers and machines, tanks and transparent pipes
Advertising industries: shop signs, decorative components and parts of sales centers, illustrated graphic signs, showcase construction
Other uses: Plastic containers, transparent engraved molds and patterns, glass cabinets used as sunbathing, soundproof walls, transportation industry, windshield and vehicle odometer protector
Transparency: Colorless polymethyl methacrylate flat plates have a transparency of 92%, which is unique in its kind. The transparency of the glass used to make the window is about 90%. The combination of transparency and weather resistance of these panels guarantees a long life for these panels, making it an ideal material for all outdoor projects.
UV resistance: UV light has destructive effects on polymers. This radiation can easily break bonds and chemical chains, leading to decomposition, discoloration, and mechanical properties. Polymethyl methacrylate naturally has superior and better UV resistance than polycarbonate.
No erosion in air: Polymethyl methacrylate flat plates have good mechanical properties, especially against atmospheric factors (wind, rain, hail, etc.) Yazd Golden Polymer Company insures these plates against atmospheric factors for 10 years. Slowly For this reason, these plates are widely used in school buildings, industrial equipment, and outdoor signs and statues.
Safety: Polymethyl methacrylate flat plates are more impact resistant than glass. If they are hit within the allowable range, they will not break and will not break into small pieces and will break into relatively large pieces.
Dimensional stability: Although polymethyl methacrylate flat sheets will expand and contract due to changes in temperature and humidity, they will never wrinkle or shrink over time. There is some shrinkage during thermal forming, but it will be very stable after that.
Lightweight: The weight of these plates is about half the weight of a glass with the same dimensions and thickness and 43% by weight of aluminum.
Suitable thermal conductivity: Polymethyl methacrylate flat sheets are better insulated than glass. Its overall heat transfer coefficient (U-Factor) is approximately 10% lower than glass of the same thickness. Therefore, today, with the increasing growth of energy prices and the discussion of optimizing energy consumption, seriously, in cases where we are looking for an alternative to glass, polymethyl methacrylate flat panels are a good choice.
Shock and heat stress resistance: Polymethyl methacrylate flat panels are more resistant to heat shock than glass as well as stresses resulting from significant temperature differences on both sides of the window.
Easy construction: Polymethyl methacrylate flat plates can be easily cut, drilled, perforated, shaped, painted, glued, etc. by following the technical instructions.
Flat sheets of polymethyl methacrylate made by Yazd Golden Polymer Company are available in thicknesses of 2.7 to 3 mm and in dimensions of 182 * 122 and transparent colors, milky, red and blue. According to the customer's order, it is possible to produce other dimensions and colors.
