Classification of single-layer PMMA

Single-layer PMMA material, Polymethyl Methacrylate, is widely used in many fields because of its excellent physical and chemical properties. Single-layer PMMA can be classified according to different classification criteria, the following are some of the main classification ways:

First, according to the production process classification

Casting plate:

Features: High molecular weight, excellent stiffness, strength and excellent chemical resistance. It is suitable for processing large-size logo plaques, which takes a little longer than in the softening process.

Application: Due to its flexibility in color system and surface texture effect, and complete product specifications, it is practical for various special purposes.

Extrusion plate:

Features: Compared with the cast plate, the extrusion plate has lower molecular weight, slightly weaker mechanical properties, but higher flexibility. It is conducive to bending and thermoforming processing, and the softening time is short. When dealing with larger plates, it is conducive to a variety of rapid vacuum blister molding.

Application: Due to the characteristics of high-volume automated production, extrusion plates may be relatively fixed in terms of color and specification, and are suitable for applications requiring rapid processing and mass production.

Second, classification by light transmittance

Transparent plate: With high transparency, light transmittance of up to 92%, it is the most common type of PMMA plate.

Translucent plate: including dyed transparent plate, etc., the light transmittance between transparent plate and opaque plate.

Opaque board: such as opal board, poor light transmission, but has a unique visual effect.

Third, classification by performance

Anti-impact plate: after special processing, with higher impact resistance, suitable for the need to withstand external impact occasions.

Anti-ultraviolet plate: the anti-ultraviolet agent is added to effectively resist the erosion of ultraviolet light and maintain the transparency and color of the material for long-term use.

Flame retardant plate: has flame retardant performance, can prevent the spread of fire to a certain extent, improve safety.

High wear plate: The surface is specially treated to have higher wear resistance and is suitable for occasions where frequent friction is required.

Fourth, classification by use

Building panels: such as daylighting roofs, doors and Windows, etc., take advantage of PMMA's high transparency and weather resistance.

Advertising boards: such as light boxes, signboards, etc., using PMMA's ease of processing and good visual effects.

Electronic boards: such as display screens, touch screens, etc., take advantage of PMMA's high transparency and insulation properties.

Medical board: such as dental repair materials, medical instruments, etc., using PMMA's non-toxic environmental protection and easy processing.

Fifth, other special categories

Recycled sheet: recycled acrylic scraps are re-polymerized after thermal degradation, although the cost is lower, but the performance may be slightly worse than the new sheet.

In summary, single-layer PMMA materials have a variety of classification methods, and each classification method has its specific application scenarios and performance characteristics. When selecting single-layer PMMA materials, comprehensive considerations need to be made according to specific needs and conditions.
