Polymethyl methacrylate can be molded, injection molded, extruded, and thermoformed.
Injection molding is performed on a common plunger or screw injection molding machine using pellets produced by suspension polymerization. The injection molded products also need to be post-treated to eliminate internal stress, and the treatment is carried out in a hot air circulating drying oven at 70-80°C. The treatment time depends on the thickness of the product, and generally takes about 4h.
Polymethyl methacrylate can also be extrusion molding, with suspension polymerization of the production of granular material to prepare plexiglass sheets, rods, tubes, sheets, etc., but the profiles prepared in this way, especially plates, due to the small molecular weight of the polymer, mechanical properties, heat resistance, solvent resistance are not as good as cast molding profiles, the advantage of high production efficiency, especially for pipes and other casting method when the mold. Difficult to manufacture profiles. Extrusion molding can be done by single-stage or double-stage exhaust extruder, with the screw L/D ratio generally at 20-25.
Acrylic rod, also known as Plexiglas rod, is a transparent plastic material that has a wide range of applications in industry, household, design and decoration. Its properties include transparency, sturdiness, impact resistance, and ease of molding, making it one of the popular materials.
1. Industrial products
Acrylic rod in the industrial aspects of the application is very wide. For example, in the automotive industry, acrylic rods can be used as car light shells, windows and other components; in the aircraft industry, can be used as cockpit windows and doors, etc.; in the chemical industry, you can make chemical test tubes, reactors and other equipment.
In addition, acrylic rods in ships, machinery, electronics, military and other fields also have a wide range of applications. As acrylic rods have good toughness and corrosion resistance, so it can be made into a variety of shapes to meet the needs of different industrial fields.
2. Home decoration
Acrylic rods can be used in a variety of home decoration. For example, in the restaurant, acrylic rods can be used as the feet of the dining table and chairs to enhance the stability of the furniture; in the bedroom, it can be made into hangers and reflectors, etc..
In addition, acrylic rods can also be used in the architectural decoration of the home. For example, in the kitchen and bathroom, acrylic rods can be made into partitions to isolate water flow; in the foyer and living room, it can be made into door signs and furniture, etc. Through the use of acrylic rods, a modern and stylish look can be created for the home
