How much does black cast acrylic sheet generally cost
Black cast acrylic sheet is highly favored in high-end display stands, LED display panels, building partitions, advertising signs, and other fields due to its deep color, excellent mechanical properties, and good processability. But in procurement, the price has left many people confused - with the same label "black cast acrylic", some quote tens of yuan per square meter, while others cost two or three hundred yuan, and even heard to be priced by kilogram. What are the hidden tricks behind the price difference that you don't know? This article will comprehensively analyze the price composition, influencing factors, and purchasing points of black cast acrylic sheets, helping you to select materials accurately and budget reasonably.
Black cast acrylic sheet is a polymer black opaque sheet made from methyl methacrylate (MMA) monomer through casting molding process. The casting process is to directly inject liquid MMA monomer into a glass mold, and slowly polymerize and solidify under constant temperature conditions. This "slow work produces fine work" process endows the casting plate with a series of unique performance advantages, making it far superior in quality to ordinary extruded plates.
High hardness and impact resistance: Cast acrylic sheets have a very high molecular weight, making them harder and crack resistant. The black cast board also inherits this characteristic. With the same thickness, its impact resistance is 6 to 8 times that of ordinary glass, making it an opaque and very durable hard board.
Excellent weather resistance: The cast board has good weather resistance, is not easily discolored or aged, and will not crack due to sun and rain exposure. Even after long-term use under strong ultraviolet radiation, the board with added ultraviolet absorbers can maintain color stability, and its outdoor service life can reach 8 to 10 years without yellowing or hydrolysis.
Excellent chemical resistance: Cast plates have excellent chemical resistance and can resist the erosion of various chemical substances, which makes them widely used in the medical field and industrial environment.
Easy to process and highly malleable: Casting boards can be processed through various methods such as cutting, drilling, hot bending, carving, etc., and the dimensions are stable and not easily deformed after processing. This is crucial for high-end applications such as LED display panels and optical instrument casings that require precision machining.
Color purity and stability: Black, as a regular color, has a relatively stable price, about 30 yuan more expensive than transparent boards, with an average price of around 80 yuan per square meter. This is because adding colorants will increase production costs and the process will be slightly more complex.
The specification system of black cast acrylic board is very complete, with mature product lines ranging from ultra-thin board to ultra-thin board. The thickness of black cast plates can generally extend from 1.5mm to 50mm or even thicker, meeting the varying requirements for load-bearing, impact resistance, and structural stability in various application scenarios.
Standard size: The most common standard size on the market is 1220 x 2440mm (4 feet x 8 feet), in addition to 1220 x 1830mm (4 feet x 6 feet), 2050 x 3050mm, 1000 x 2000mm and other specifications to choose from. Customized size is also a major advantage of casting boards, and manufacturers can cut them according to their needs.
Thickness specification: Conventional thickness covers 1.5 mm、2mm、3mm、4mm、5mm、6mm、8mm、10mm、12mm、15mm、20mm、25mm、30mm、40mm、50mm Almost all common thicknesses are available.
Recommended thickness for use: 1-2mm ultra-thin board suitable for LED display panel backlight layer and fine cutting; 3-5mm thin plate is suitable for advertising light boxes, display stands, and signage, and is the main specification in the market; 8-10mm medium thick plate is used for furniture partitions, equipment covers, and large-span displays; Thick plates over 12mm are used for load-bearing structural components and large-scale projects.
Black cast acrylic has a wide range of applications due to its pure color, strong light blocking ability, and high-quality texture
LED display and backlit characters: Black and black tea colored models are widely used in LED display panels, backlit characters, exhibition props, and other fields due to their strong light blocking properties and advanced color rendering. The visible light transmittance of the black tea semi transparent board can be stable in the range of 30% -50%. When light passes through, it will naturally soften and blend, forming a warm and non glaring diffuse effect.
Commercial display and advertising signs: Black cast acrylic board can be used in various fields such as advertising signs, exhibition displays, commercial space decoration, lighting fixtures, etc. Its advanced black texture and high stability make it the preferred material for high-end display cabinets and brand image walls.
Architecture and interior decoration: shop windows, soundproof doors and windows, daylighting covers, wall panels, furniture finishes, ceiling decorations, etc. Black acrylic board is used for walls, ceilings, and furniture pasting, without hurting hands, also known as "safety mirror".
Furniture, bathroom and industrial applications: can be applied to kitchen countertops, bathroom partitions, furniture decoration, equipment protective covers, instrument panels, medical equipment casings, etc. Black cast acrylic also has excellent chemical resistance and weather resistance, making it suitable for industrial environments with high durability requirements.
Automotive Interior and Transportation Field: Automotive interior, transportation tracks, trains, cars, and other vehicle doors and windows are also widely used in various fields.
The production process of black cast acrylic can be vividly understood as "the liquid raw material slowly solidifies in the mold", which is fundamentally different from the extrusion process of "continuous extrusion like a rolling pin pressing the dough". The casting process is the fundamental reason for endowing black sheet metal with excellent quality.
Raw material preparation: Select MMA monomer, add initiator, accelerator, required black color powder, anti UV agent and other additives according to the formula, and filter to ensure that the raw materials are clean and free of impurities.
Ingredients and defoaming: Mix and stir the ingredients in proportion to evenly disperse the black color. Subsequently, vacuum degassing is carried out to remove air from the mixture and prevent the formation of bubbles inside the board.
Casting into mold: Two pieces of glass are used as the mold, with a sealing strip in the middle to control the thickness and clamp it in place. Slowly inject the defoamed black monomer mixture into the mold to ensure even filling.
Aggregation curing: Place the mold in a constant temperature environment and heat it to gradually polymerize the monomers into PMMA solid. Temperature is controlled in stages to reduce internal stress and ensure the quality of the board.
Cooling and demolding: Slowly cool down after curing to prevent deformation or cracking. After cooling to the specified temperature, remove the mold and take out the black board.
Post processing and finished product finishing: trimming, testing, and annealing the board to release residual stress. Finally, cut, film, and inspect according to specifications before packaging and storing.
The core points of the production process: the production cycle of cast plates is longer than that of extruded plates, and black cast plates have higher requirements for raw material purity and process control due to the addition of color powder and other additives. This is one of the reasons why the price of black cast plates is higher than that of transparent plates. The entire polymerization and curing process from raw materials to finished products requires strict control of temperature and time. The polymerization time for thin plates is relatively short, while thick plates require longer time.
Q1: What is the approximate price of black cast acrylic sheet?
The price of black cast acrylic sheet is determined by its thickness, raw material grade, and production process. According to market trends, black, as a regular color, is about 30 yuan more expensive than transparent panels, with an average price of around 80 yuan per square meter. The overall price of cast board is about 100-150 yuan/square meter, while extruded board is about 50-100 yuan/square meter. Specifically for different thicknesses, 2mm is about 60-90 yuan/㎡, 3mm is about 80-120 yuan/㎡, 5mm is about 120-180 yuan/㎡, 8mm is about 180-280 yuan/㎡, and thick plates above 10mm are mostly priced per kilogram (about 20-35 yuan/kg). Imported brands or black cast boards made from 100% imported raw materials have higher prices, ranging from 200 to 400 yuan/square meter or more.
Q2: Why is black cast acrylic board more expensive than transparent board?
There are two reasons for this. One is the cost of colorants - producing black boards requires the addition of high-quality black colorants, which itself increases material costs. The second is the complexity of the process - colorants need to be uniformly dispersed in MMA monomers during the polymerization stage, which is slightly more complex than transparent plates in terms of process and requires higher equipment cleanliness and process control requirements.
Q3: Is there a big difference between cast black board and extruded black board?
The difference is very significant. Casting board has high molecular weight, good rigidity, crack resistance, and no crystal points on the surface, suitable for laser engraving and precision machining; The molecular weight of the extruded board is relatively low, and its mechanical properties are slightly weaker. Due to the characteristics of the extrusion process, fine patterns or crystal dots may appear on the surface. For outdoor use or scenarios that require high surface smoothness, it is recommended to prioritize the use of cast plates.
Q4: How to distinguish the quality of black cast acrylic board?
Although black is opaque, there are still ways to distinguish it: look at the edges - the edges of the casting board are cut smooth and transparent without any blemishes; Smell - When cutting the casting plate, there is a small odor and less smoke, while when cutting the return plate, there is a pungent odor and more smoke; Check thickness - measure the corners and middle with a caliper, and control the thickness tolerance of high-quality sheet within ± 0.2mm; Packaging inspection - The new material board has a protective film with soft rubber edge packaging when it leaves the factory. When making a purchase, you can request a sample and use a flashlight to shine from the edge to observe the uniformity of the light inside the board and whether there are obvious impurities.
Q5: What is the price calculation formula for black cast acrylic board?
Price per sheet: Single sheet price (yuan)=length (m) x width (m) x thickness (mm) x density (1.2) x unit price per kilogram (yuan/kg). Taking 1220 × 2440 × 3mm as an example: 1.22 × 2.44 × 3 × 1.2 × 20 ≈ 214 yuan/sheet (approximately 71 yuan per square meter), this is the reference price for new transparent boards. The black board needs to be floated up by 10% -20% on this basis as the color difference.
