Acrylic (PMMA)
Retlaw Industries Acrylic Manufacturing
Acrylic Used in Plastic Injection Molding
Poly(methyl methacrylate), also known as acrylic, is a clear thermoplastic homopolymer often used as a more resistant alternative to glass. Acrylic is the most common type of clear, moldable plastic available to the general public, and it can be used for anything from windows and picture frames to fake nails and paint.
Some of the benefits of using acrylic plastic include:
- Transparent properties
- Weather resistance
- Chemical resistance
- Surface Hardness
- Dimensional Stability
- Non-toxic composition
The chemical properties of acrylic allow it to be completely transparent while remaining hard and highly resistant to scratches and impact. Acrylic can be easily molded into different shapes and sizes, meaning it can be an economic substitute for other types of hard plastic. The professional molding experts at Retlaw Industries can use acrylic material for your specific molded plastic part.

Challenges of Working with PMMA Acrylic Plastic
As with any plastic material, there are some common issues that could potentially arise in the PMMA thermoplastic molding process. Some of the problems that could occur include:
- Materials produced with PMMA Acrylic have a lower resistance to impact compared to metal injection molded parts.
- Acrylic products tend to have low heat resistance (About 175°F).
- Acrylic products have lower mechanical strengths which could limit their loading capacities.
- Some acrylic products have poor chemical resistance, which makes them prone to react badly.
Acrylic in Everyday Life
Many plastic products we use every day are manufactured with acrylic resin. Some of these products include:
- Plexiglas windows
- Beauty products
- Paint
- Fashion accessories
- Eyeglass lenses
- And much more
Acrylic is one of the most affordable plastics available to the general public. Its impact-resistant structure makes it one of the most useful plastics for a wide variety of applications, including where clear, impact-resistant material is needed.
