What is an acrylic sheet?

The Chinese name of acrylic is transliterated from English Acrylics, and the Chinese common names are acrylic and acrylic. A generic term for acrylic and methacrylic chemicals. Includes monomers, sheets, pellets, resins, and composites. Acrylic sheet is polymerized from methyl methacrylate monomer (MMA), namely polymethyl methacrylate (PMMA) sheet plexiglass, which is a kind of plexiglass processed by special process.

The research and development of acrylic has a history of more than 100 years, and it has the reputation of "Plastic Queen".

Performance characteristics

1. The density is light. Acrylic is a very light material. The density is only 1.19-1.20, which is about half of ordinary glass and 43% of metal aluminum;

2. It has good flame resistance, will not spontaneously ignite and can self-extinguish;

3. It has excellent electrical insulation and is a very suitable high-frequency insulating material for the radio instrument industry;

4. It has good light transmittance, the light transmittance can reach more than 92%, which is more than 10% higher than ordinary glass, and has a crystal-like texture and luster;

5. Not afraid of moisture, water, mildew, bacteria, corrosion resistance;

6. The impact resistance is sixteen times that of ordinary glass, and there is almost no danger of breakage.
Classification of acrylic

Acrylic sheets are divided into cast sheets and extruded sheets according to the production process. According to the transmittance, they can be divided into transparent sheets and translucent sheets (including dyed sheets and transparent sheets); Black and white and color boards), ordinary boards and special boards such as high impact boards, flame retardant boards, frosted boards, metal effect boards, high wear-resistant boards, light guide boards, etc.

Acrylic molding process

Acrylic molding processes commonly used in industrial production include casting, injection molding, extrusion, thermoforming, etc.

Casting molding is mainly used for the molding of acrylic sheets, bars and other profiles, and the molded products need to be post-processed before they can be used. Cast acrylic sheet has strong stiffness, strength and excellent chemical resistance, and has unparalleled flexibility in color system and surface texture effect.



Injection molding uses pellets obtained by suspension polymerization as raw materials, and is molded on a common plunger or screw injection molding machine. It should be noted that due to the poor fluidity of acrylic particles, the flow resistance of the injection molding system should be small, the gate should use a larger size side gate, the surface of the cavity and runner should be smooth, and post-processing is required after molding. to relieve internal stress.



Extrusion molding is to extrude the acrylic particles produced by suspension polymerization into acrylic sheets, rods, pipes, sheets, etc. Acrylic products made by extrusion molding have low molecular weight, weak mechanical properties, low heat resistance and solvent resistance, but this process has high production efficiency and high product flexibility, which is conducive to bending and thermoforming.
