Makrolon AR vs Lexan MR10: A Comprehensive Comparison

When it comes to choosing the right polycarbonate material for your project, it’s essential to understand the differences between Makrolon AR and Lexan MR10. Both are renowned for their durability, clarity, and resistance to impact, but they have distinct characteristics that make them suitable for different applications. Let’s delve into a detailed comparison of these two materials to help you make an informed decision.

Material Composition

Makrolon AR is a polycarbonate material produced by Bayer MaterialScience, while Lexan MR10 is manufactured by SABIC. Both materials are composed of polycarbonate, a thermoplastic polymer known for its high impact resistance and transparency. However, the specific formulations and additives used in each material contribute to their unique properties.

Impact Resistance

One of the primary reasons for choosing polycarbonate materials like Makrolon AR and Lexan MR10 is their exceptional impact resistance. Both materials can withstand high levels of force without cracking or breaking. According to data from Bayer MaterialScience, Makrolon AR has an impact strength of up to 200 J/m虏, while Lexan MR10 boasts an impact strength of up to 250 J/m虏. This means Lexan MR10 is slightly more resistant to impact than Makrolon AR.

Clarity and Transparency

Clarity and transparency are crucial factors when selecting a polycarbonate material for applications such as windows, visors, and display cases. Both Makrolon AR and Lexan MR10 offer excellent clarity, with a light transmission of over 90%. However, Lexan MR10 has a slightly higher light transmission rate of 92% compared to Makrolon AR’s 90%. This means Lexan MR10 provides a brighter, more vibrant appearance.

UV Resistance

UV resistance is another important consideration, especially for outdoor applications. Both Makrolon AR and Lexan MR10 offer good UV resistance, but Lexan MR10 has a higher resistance to UV radiation. This is due to the presence of UV inhibitors in its formulation, which protect the material from degradation caused by prolonged exposure to sunlight. As a result, Lexan MR10 is more suitable for outdoor applications than Makrolon AR.

Thermal Properties

Thermal properties are essential for ensuring that the polycarbonate material can withstand temperature variations without deforming or losing its properties. Makrolon AR has a heat deflection temperature (HDT) of up to 135掳C, while Lexan MR10 has an HDT of up to 150掳C. This means Lexan MR10 is more resistant to heat and can be used in applications with higher temperature requirements.

Chemical Resistance

Chemical resistance is another critical factor when selecting a polycarbonate material. Both Makrolon AR and Lexan MR10 are resistant to a wide range of chemicals, including aliphatic hydrocarbons, alcohols, and esters. However, Lexan MR10 has better resistance to aromatic hydrocarbons and ketones compared to Makrolon AR. This makes Lexan MR10 a more suitable choice for applications involving harsher chemicals.

Applications

Understanding the applications for which each material is best suited can help you make an informed decision. Makrolon AR is commonly used in automotive applications, such as visors, windows, and interior components. Lexan MR10, on the other hand, is often used in outdoor applications, such as signage, outdoor lighting, and architectural glazing.

Cost and Availability

Cost and availability are also important factors to consider when choosing between Makrolon AR and Lexan MR10. Both materials are widely available and can be purchased from various suppliers. However, the cost may vary depending on the specific grade and quantity required. It’s essential to compare prices from different suppliers to ensure you’re getting the best deal.

Conclusion

In conclusion, both Makrolon AR and Lexan MR10 are excellent polycarbonate materials with unique properties that make them suitable for various applications. Lexan MR10 offers superior impact resistance, UV resistance, and thermal properties compared to Makrolon AR. However, Makrolon AR is still a viable option for certain applications, particularly those that require high clarity and chemical resistance. Ultimately, the choice between these two materials will depend on your specific project requirements and budget.
