Difference Between Lexan and Plexiglass

Definition of Lexan and Plexiglass

Lexan and Plexiglass are two different types of transparent plastic materials used in various applications.

Lexan, also known as polycarbonate, is a thermoplastic material that is lightweight, shatter-resistant, and highly impact-resistant. It has high optical clarity and can withstand extreme temperatures, making it suitable for use in applications where safety and durability are essential, such as in the construction, automotive, and electronic industries.

Plexiglass, also known as acrylic, is a thermoplastic material that is transparent and rigid, similar to glass. It is lightweight, scratch-resistant, and has excellent optical clarity. Plexiglass is often used as a substitute for glass in various applications, including signage, aquariums, and display cases, as it is more shatter-resistant and easier to fabricate than glass.

Importance of understanding the difference between the Lexan and Plexiglass

It is important to understand the difference between Lexan and Plexiglass as they have different properties, strengths, and weaknesses, and are used in different applications. Choosing the right material for a particular application is crucial to ensure safety, durability, and cost-effectiveness.

For example, if impact resistance and safety are a priority, Lexan may be a better choice than Plexiglass as it can withstand extreme impacts and is shatter-resistant. On the other hand, if optical clarity and scratch resistance are more important, Plexiglass may be the better option as it has excellent optical clarity and is less prone to scratching.

Choosing the wrong material for a particular application can lead to safety hazards, premature material failure, and additional costs associated with replacement and maintenance. Therefore, it is important to understand the differences between these two materials and their suitability for specific applications.

What is Lexan?

Lexan is a brand name for polycarbonate, which is a transparent thermoplastic material. It was first developed by General Electric in the 1950s and is now produced by Sabic Innovative Plastics.

Polycarbonate is a strong and durable material that is often used as a substitute for glass. It is lightweight, shatter-resistant, and highly impact-resistant, making it an excellent choice for applications where safety and durability are essential.

In addition to its strength and impact resistance, Lexan has other properties that make it suitable for various applications. It has high optical clarity, which makes it ideal for use in transparent barriers and windows. It also has high resistance to UV radiation, weathering, and chemicals, which makes it suitable for outdoor and harsh environments.

Lexan is used in a wide range of applications, including automotive parts, electrical enclosures, safety glasses, aircraft and marine glazing, and electronic components. It is also used in the construction industry for roofing and skylights, as well as in the medical industry for surgical instruments and equipment.

What is Plexiglass?

Plexiglass is a brand name for acrylic, which is a transparent thermoplastic material. It was first developed in the 1930s by Rohm and Haas Company and is now produced by various manufacturers.

Acrylic is a rigid, transparent material that is often used as a substitute for glass. It is lightweight, scratch-resistant, and has excellent optical clarity. It is less brittle than glass and is more shatter-resistant, making it safer in certain applications.

In addition to its clarity and durability, Plexiglass has other properties that make it suitable for various applications. It is resistant to UV radiation and weathering, making it suitable for outdoor use. It is also easy to fabricate, allowing it to be molded into various shapes and sizes.

Plexiglass is used in a wide range of applications, including signs, display cases, aquariums, windows, and skylights. It is also used in the aviation industry for airplane windows and in the medical industry for dental implants and prosthetics.

Differences between Lexan and Plexiglass

There are several differences between Lexan and Plexiglass, including:

1. Manufacturing process: Lexan is a polycarbonate that is produced through an injection molding process, while Plexiglass is an acrylic that is produced through a cell-casting or extrusion process.
2. Strength and durability: Lexan is stronger and more impact-resistant than Plexiglass. It can withstand extreme temperatures and has better resistance to breakage, making it ideal for applications where safety and durability are critical.
3. Clarity and transparency: Plexiglass has better optical clarity and transparency than Lexan. It has a higher refractive index, which means that it is more transparent and has a clearer view than Lexan.
4. Scratch resistance: Plexiglass has better scratch resistance than Lexan. It is less prone to scratches and can be easily repaired, while Lexan can easily scratch and is difficult to repair.
5. Chemical resistance: Lexan has better chemical resistance than Plexiglass. It can withstand exposure to various chemicals, while Plexiglass can be damaged by certain chemicals.
6. Cost: Plexiglass is generally less expensive than Lexan, making it more cost-effective for certain applications.

When choosing between Lexan and Plexiglass, it is important to consider the specific application and its requirements, as well as the strengths and weaknesses of each material.

How to choose between Lexan and Plexiglass

Choosing between Lexan and Plexiglass depends on the specific application and the requirements of the project.

Here are some factors to consider when choosing between these two materials:

1. Strength and durability: If the application requires high-impact resistance and safety, Lexan may be the better choice due to its superior strength and durability.
2. Clarity and transparency: If the application requires excellent optical clarity and transparency, Plexiglass may be the better option as it has better clarity and a clearer view than Lexan.
3. Scratch resistance: If the application is prone to scratches, Plexiglass may be the better choice as it has better scratch resistance and is easier to repair.
4. Chemical resistance: If the application requires exposure to various chemicals, Lexan may be the better option as it has better chemical resistance than Plexiglass.
5. Cost: If cost is a factor, Plexiglass is generally less expensive than Lexan, making it more cost-effective for certain applications.

The choice between Lexan and Plexiglass will depend on the specific application, the requirements of the project, and the strengths and weaknesses of each material. It is important to carefully evaluate these factors to ensure that the chosen material is suitable for the application and will meet the necessary performance requirements.

Conclusion

Lexan and Plexiglass are two different materials used as alternatives to glass due to their strength, durability, and transparency. Lexan is a polycarbonate known for its superior impact resistance and strength, making it suitable for applications that require high safety and durability. On the other hand, Plexiglass is an acrylic known for its excellent optical clarity, scratch resistance, and cost-effectiveness.

Choosing between Lexan and Plexiglass depends on the specific application and requirements of the project. By carefully evaluating the factors mentioned above, one can make an informed decision and choose the material that best suits the project’s needs.
