What is acrylic plastic sheet?

Definition of acrylic plastic sheet

Acrylic sheet, also namely, plexiglass or polymethyl methacrylate (PMMA), is a type of high molecular thermoplastic sheet. It is clear, transparent, or has color. It features high transparency, chemical stability, and weather resistance. It is easy to dye, and process.

Features of plexiglass plastic sheet

Acrylic sheet mechanical features

  1. It has lower density than glass. It has density of 1.15-1.19g/cm³, about half than glass and 43% of aluminum. It has deformation temperature 76-116℃, molding shrinkage 0.2-0.8%.
  2. PMMA plastic sheet has quite high mechanical strength. It has almost 2 million relative molecular. PMMA has long-chain polymer. And the chain is very soft. This help PMMA sheet has high strength. It has tensile and impact resist ability 7 to 18 times higher than ordinary glass.
  3. Acrylic sheet has melting temperature of 130-140°C (265-285°F), much lower than that of glass.
  4. Acrylic sheet has great transparency, with transmittance rate reaching 92%, higher than that of glass.
  5. PMMA glass transition temperature is around 105°C.
  6. PMMA sheet has excellent weathering resistance. In a 4 years of natural aging test, weight of the samples changes slightly. And its tensile strength and light transmittance decreased slightly. Its color is slightly yellowed. Obviously, the impact strength is slightly improved, and other physical properties are almost unchanged.
  7. PMMA sheet has good comprehensive mechanical properties. It ranks in the forefront of general-purpose plastics. It has great tensile, bending, and compressive strengths, higher than those of polyolefins, polystyrene and polyvinyl chloride. Although, its impact toughness is poor, it is slightly better than polystyrene. Cast acrylic sheet has even better strength. It can even reach the level of engineering plastics such as polyamide and polycarbonate.

Acrylic sheet chemical features

  1. Due to larger branching, PMMA has a higher viscosity. It is suitable to a slower processing speed when using thermal processing methods.
  2. Cyanoacrylate, dichloromethane or chloroform can all dissolve the plexiglass slightly. They can help bond two pieces of plexiglass together firmly.
  3. It takes about 2 kg of oil to produce around 1 kg of PMMA.
  4. PMMA sheet is easy to burn, with a limiting oxygen index of only 17.3.
  5. With oxygen, PMMA starts to burn at 458°C. This will produce carbon dioxide, water, carbon monoxide and some low-molecular-weight compounds including formaldehyde.
  6. PMMA sheet has good resistance to gases such as ozone and sulfur dioxide.

Acrylic plastic sheet production

There are mainly two production methods of producing acrylic sheet.

Extruding acrylic/PMMA plastic sheet

It is produced by extruding machine. Compared with cast sheet, it has lower molecular weight. It is slightly weaker in mechanical properties. And it has higher flexibility. However, this feature helps reduce shorter softening time, during bending and thermoforming. This would be quite beneficial to various large-size rapid vacuum forming.

Furthermore, the thickness tolerance of extruded acrylic sheet is smaller than that of cast sheet. Due to large-scale automatic production of extruded sheets, color and specifications are inconvenient to adjust. Therefore, its variety of product specifications is limited to a certain extent.

Casting acrylic/PMMA plastic sheet

Cast acrylic sheet has higher molecular weight, excellent stiffness, strength, and chemical resistance. Therefore, it is more suitable for processing large-sized logo plaques. It has longer softening time. Casting is suitable for small batch processing. It has outstanding flexibility in color and surface texture options. And its specifications is more diversified.

During casting, acrylic sheet realize complete structural polymerization. And some ultraviolet absorber is added. It has extremely high strength and UV function, quite suitable for outdoor use. Its outdoor service life reaches more than 5 years or even 10 years. And its color remains bright and new during use.

Acrylic plastic sheet machining, fabrication and molding

Acrylic sheet has good mechanical fabrication capability. It is suitable for CNC routing, laser cutting, thermal bending, vacuum forming, polishing, assembly, bonding, UV printing.

  • Acrylic sheet CNC machining, lasering, engraving
  • Acrylic sheet Bonding
  • Acrylic sheet Bending and thermoforming

Q&A about acrylic plastic sheet

1. What is acrylic plastic sheet?

Acrylic sheet is also called plexiglass or PMMA sheet. It has great transparency and mechanical ability.

2. What is acrylic plastic used for?

Acrylic sheet is a type of popular plastics, used in outdoor advertisement signs, display, dome, lighting, buildings, vehicles, and so on.

3. What is the difference between plastic sheet and acrylic sheet?

Acrylic sheet is mostly clear and transparent. It is quite similar to polyacrylate sheet. However, it has less strength and more easy to crack. However, it has better performance than clear polystyrene sheet, in terms of strength.

4. Is acrylic plastic sheet cheap?

Normally, acrylic sheet is cheaper than PC sheet, and ABS plastic sheet, and more expensive than polystyrene sheet. Cast acrylic sheet is more expensive than extruded plastic sheet.

5. Is acrylic sheet waterproof?

Yes, like other plastic sheet, acrylic sheet is waterproof. They can be used at home, office and sometimes outdoors.

6. What are the two main kinds of acrylics?

Extruded acrylic sheet and cast acrylic sheet.

7. Which is better acrylic or PVC?

Acrylic sheet has better transparency. It is more eco-friendly.

8. Does acrylic sheet turn yellow?

Yes. Under sunshine, within a certain period of use, acrylic sheet will age and turn yellowish.

9. Which is cheaper glass or acrylic?

Generally speaking, acrylic sheet is more expensive than glass sheet.

10. Is acrylic stronger than glass?

Acrylic sheet is not easy to shatter or crack, compared with glass sheet.

11. Does acrylic scratch easily?

Compared with glass sheet, acrylic sheet is more easy to scratch.
