Acrylic sheets are polymerized from MMA to form PMMA. This material, also known as plexiglass, is an organic glass produced through special processing techniques. The research and development of acrylic has a history of more than one hundred years.
Processing Performance
According to the production process, acrylic sheets are divided into cast sheets and extruded sheets. They can be thermoformed through molding, blow forming, or vacuum forming. They can also be machined by drilling, turning, milling, and cutting.
Cast Acrylic Sheet:
Cast acrylic sheets have a high molecular weight. Rigidity is excellent. Strength is high. Chemical resistance performs well. Suitable for small-batch production. Color selection is flexible. Surface textures vary. Specifications are complete. Ideal for special applications.
Extruded Acrylic Sheet:
Extruded acrylic sheets have a lower molecular weight. Mechanical strength is slightly weaker. Bending is easier. Thermoforming is easier. Large sheets process efficiently. Rapid vacuum forming works well. Thickness tolerance is more stable. Since extrusion is a highly automated mass-production process, color and specification adjustments are less flexible, which limits product variety.
Thermoforming has long been one of the most creative application methods for acrylic sheets. With continuous improvement in processing technologies and material performance, acrylic products now outperform traditional advertising materials in convenience, safety, and cost-effectiveness.
Hardness is one of the key indicators reflecting cast acrylic production technology and quality control. It indicates the purity of MMA monomers and the durability of the sheet against heat and weathering. Hardness directly affects whether the sheet warps, shrinks, cracks, or deforms during processing. Cast acrylic sheets typically reach a Rockwell hardness of around 90, representing the highest current standard.
Advantages
Exceptional outdoor weather resistance. UV-absorbing coatings and high-grade automotive paint finishes ensure long-lasting durability and color stability for 5–8 years.
Crystal-clear transparency. Acrylic is 200 times stronger than glass with minimal risk of breakage.
High surface gloss and outstanding light transmission up to 93%. Light appears soft, bright, and visually appealing.
Available in transparent, translucent, opal, and other colors with multiple surface textures. Formed with modern polyester materials and integrated lighting, acrylic products deliver strong visual impact.
Excellent processing performance. Thermoforming allows creative and cost-effective signage with mirror-finish lettering and seamless structure design.
Environmentally friendly. Waste materials can be fully recycled. High light transmission reduces energy consumption and operating cost.
Superior surface hardness and scratch resistance. Internal lighting remains well-protected, extending service life.
Strong chemical resistance, outperforming most plastics.
Easy to clean and maintain. Weather-resistant structural design protects against moisture and allows convenient servicing.
Flame-retardant characteristics. Acrylic does not self-ignite and will self-extinguish.
Application Fields
In architecture, acrylic is widely used for skylights, roofing, canopies, stair panels, and interior wall protection. Acrylic lighting covers and automotive lamp housings are expanding rapidly. Skylights made from extruded acrylic sheets offer high structural strength, light weight, excellent transparency, and enhanced safety, making them superior to traditional glass systems.
