Q: What is Acrylic (PMMA)?        Acrylic is called "polymethyl methacrylate" Poly (methyl methacrylate), referred to as PMMA, also known as plexiglass, has the reputation of "plastic crystal", and is often used as a substitute for glass. 92% light transmittance, good weather resistance, easy machining, can be adhered with chloroform, and suitable for all kinds of painting and printing (suitable for acrylic materials).           The basic chemical structure of acrylic resin is acrylic acid (Acrylic acid), which is a by-product of petroleum extraction. The scientific name of acrylic resin is Poly Methyl Methacrylate. In 1920, Rohm And Hass Company developed a synthetic resin.   The chemical substance whose chemical molecular structure is CH2=CH(CH3)COOCH3 can be regarded as an ester compound obtained by the reaction of methanol and methacrylic acid, commonly known as acrylic monomer (MMA).          A monomer refers to a "chemical substance" with a "low and fixed molecular weight" that can be polymerized into a polymer of high molecular weight, or the basic unit that constitutes a polymer. For example, methyl methacrylate (MMA), which has a molecular weight of 100.1, can be obtained as a high molecular weight homopolymer or copolymer by various polymerization techniques. Polymer refers to high molecular weight substances, such as polymethyl methacrylate (PMMA), usually the molecular weight obtained by the casting method is greater than 1 million (Plastic pellets for extrusion and injection) Acrylic refers to a type of plastic material that is derived from acrylic acid. It is commonly used in various applications due to its versatility and desirable properties. Acrylics can be found in both liquid and solid forms, and they are widely used in industries such as manufacturing, construction, automotive, textiles, and art.   Additionally, acrylic sheets or panels are commonly used in applications where transparency, impact resistance, and weatherability are required. These sheets can be used as a substitute for glass in certain applications like windows, signage, displays, and protective barriers. Acrylic sheets come in various thicknesses and can be easily shaped and fabricated for specific purposes. Here are some important properties about Acrylic : Transparency: Acrylic is very transparent, similar to glass. This makes it ideal for creating transparent or translucent products such as display windows, display boards, signage, etc.   Weather Resistance: Acrylic has good weather resistance to sunlight and climate changes in the atmosphere. It is not prone to yellowing, fading or becoming brittle due to prolonged exposure to sunlight.   Lightweight: Compared to glass, acrylic is lighter. This makes it more suitable in applications requiring lightweight construction, while also aiding transportation and installation.   Ease of Processing: Acrylic is fairly easy to cut, shape, and process. This material can be produced in various forms, including sheets, tubes, profiles, etc., and can meet the needs of different shapes and sizes.   Chemical resistance: Acrylic is highly resistant to many chemicals and is not easily corroded by acids and alkalis. Therefore, it is widely used in laboratories, medical equipment, and chemical industries.   Thermoformability: Acrylic can be thermoformed under certain heating conditions, so manufacturers can make products of various shapes according to needs.   Colorful: Acrylic can be dyed into various colors and has high gloss, which makes it widely used in art, decoration and other fields.   Impact resistance: Acrylic is more tough than glass and has better resistance to impact, reducing the risk of breakage. Overall, acrylic is a versatile material with diverse applications, ranging from art to industrial and commercial uses. Further Reading：PMMA V.S. GLASS  

Q: Acrylic Cast Tube At present, SMEACRYLIC extruded acrylic tube, which can produce a maximum outer diameter of 250mm, but if you need a larger size, you can consider Cast Tube, the outer diameter can reach 600mm, Thickness 10mm, The length is 1.0~1.2M. The manufacturing process is based on liquid MMA raw material, poured into the tube mold, and formed by the centrifugal principle. The dimensional tolerance is large, the process is long, and one piece can be produced. It is suitable for small-scale production. Better, because the molecular weight is high, it can withstand temperature of about 90 degrees, but there will be fine cloth wheel throw marks on the surface.

Q: SMEACRYLIC packaging       Different from the packaging methods of other factories, 99% of the acrylic products produced by SMEACRYIC are packed in cartons. The advantages of this packaging are: ◆ Convenient warehouse management and control, transparent specifications and quantities. ◆ Properly protect the product to avoid bumps and injuries. ◆ Square arrangement storage, maximize the warehouse. 1. The acrylic sticks are 3-5mm in diameter and are directly bundled in a bundle of 50 pieces. When customers sell, they can save the time for inventory, and increase the strength of the sticks, which is not easy to break.   2. For acrylic rods with a diameter of more than 6mm and acrylic tubes of 8~28mm, each piece is put into a PE bag, which can reduce the risk of friction and scratches on the acrylic rod and strengthen the protection of each acrylic rod/tube. 3. The round tube over 3.30mm is packed with shrink film, and the large tube is then inserted into a round fixed piece to avoid deformation by external force. In addition to slowing down the water absorption of acrylic, it can also reduce the scraping of acrylic fragments during processing and cutting. The risk of injury is not affected by the visual gap between the PE bag and the tube. Always pallet packaging by CFS In order to ensure that the bulk cargo can be safely delivered to the customer, when the bulk cargo is shipped, it must be packaged on pallets to avoid product damage caused by bulk cargo handling. Secured with iron straps. Remarks: Air freight may not necessarily be shipped on pallets due to consideration of customer shipping costs. FCL shipment by sea For customers who leave the whole container, after completing the loading, be sure to pull the rope to protect the goods, and record the photos of the empty container, seal, before and after sealing, so as to ensure the rights and interests of customers.
