Polycarbonate vs Acrylic: The Best Material for Your Motorcycle Windshield

As the open road beckons to motorcycle enthusiasts worldwide, the importance of safety and performance becomes increasingly apparent. One often overlooked, yet essential, component of motorcycle safety and performance is the windshield. Made to protect riders from wind, debris, and other potential hazards, a motorcycle windshield’s material is critical in determining its durability, functionality, and lifespan.

In this comprehensive blog post, we delve into a detailed comparison of two popular windshield materials – polycarbonate and acrylic, unraveling their strengths and weaknesses to help you make an informed choice for your trusty two-wheeler.


Understanding Polycarbonate

Polycarbonate, a type of thermoplastic polymer, is renowned for its extraordinary strength and impact resistance. Frequently used in safety gear, bulletproof windows, and, of course, motorcycle windshields, polycarbonate stands up remarkably well to the high-speed rigors of the open road. This resilience makes it a popular choice among those who prioritize safety and durability.

Despite its robust nature, polycarbonate is surprisingly lightweight. This weight advantage contributes to better motorcycle handling and fuel efficiency, a feature that is often a determining factor for long-distance riders or those who frequently navigate challenging terrains.

However, the material isn’t without its drawbacks. Without additional protective coating, polycarbonate is prone to scratches and can become yellow over time due to UV exposure.

Exploring Acrylic

Next up is acrylic, a transparent thermoplastic also known as plexiglass. Acrylic is celebrated for its optical clarity and high gloss finish, characteristics that lend it an aesthetically pleasing look. This material is also more resistant to scratches than polycarbonate, making it easier to maintain and clean.

Acrylic’s impact resistance, however, is moderate compared to polycarbonate. Although it can withstand small debris, an acrylic windshield might crack or shatter upon significant impact, raising some safety concerns for high-speed or off-road riders. Acrylic also offers less flexibility, meaning it might not be the ideal choice for complex or highly curved windshield designs.

Safety Considerations

Safety is paramount when considering motorcycle windshield material. Polycarbonate’s superior impact resistance gives it an edge over acrylic, especially during accidents or collisions.

An impact that might cause an acrylic windshield to crack or shatter will likely only dent a polycarbonate one. Nonetheless, acrylic can still offer sufficient protection against most road hazards, particularly at lower speeds or in less demanding riding conditions.

Durability and Weather Resistance

Both materials offer good durability, but each has distinct challenges. Polycarbonate, while virtually unbreakable, is more prone to scratches and UV damage. An additional UV-resistant coating can counter this, but it will add to the overall cost.

On the other hand, acrylic is more naturally UV resistant and less prone to scratching. However, it is more brittle and can crack or shatter under significant stress. Its susceptibility to stress-cracking, especially under exposure to certain cleaning chemicals, is another factor to consider when assessing long-term durability.

Optics and Clarity

In the realm of optical properties, acrylic undoubtedly takes the lead. This material offers exceptional clarity and minimal distortion, making it an ideal choice for riders who prioritize unobstructed, clear views. The minimal color distortion and light bending properties of acrylic add to its appeal.

Polycarbonate, conversely, can exhibit some optical distortion due to its inherent softness. However, this drawback is often addressed in high-quality polycarbonate windshields through corrective designs, ensuring that the distortion is kept to a bare minimum, maintaining a satisfactory level of rider visibility.

Maintenance and Care

Maintenance is crucial for both polycarbonate and acrylic windshields, requiring careful cleaning routines to maintain their clarity and prolong their lifespan. For polycarbonate windshields, it is recommended to use a soft cloth and warm, soapy water for optimal results.

This method effectively cleans without damaging the surface. It’s crucial to avoid using ammonia-based cleaners, as they can cause clouding or yellowing over time, affecting the windshield’s overall aesthetics and performance.

Similarly, acrylic windshields, while considerably more resistant to scratches, can become compromised when exposed to harsh chemicals, leading to potential cracks. Mild soapy water and a soft, non-abrasive cloth are ideal for cleaning these windshields, ensuring longevity and sustained clarity.

Cost Comparison

The costs associated with polycarbonate and acrylic windshields can be quite distinct. Generally, polycarbonate windshields are more expensive, mainly due to their superior impact resistance and flexibility—traits that ensure enhanced safety and versatile use. The extra expense can indeed be justified, especially if safety and versatility are high on your priority list.

Acrylic windshields, while offering a more affordable initial investment, might require more frequent replacement due to its lower impact resistance and susceptibility to cracking or shattering. It’s crucial to factor in these long-term costs when making your selection.

Customization Options

Both polycarbonate and acrylic offer a range of customization options to suit varying rider preferences and motorcycle designs. The superior flexibility of polycarbonate allows it to be molded into more complex or curvaceous shapes, thus fitting a wider range of motorcycle designs.

Acrylic, although less flexible, can be effectively cut, heated, and polished to create a wide array of shapes and designs, providing more aesthetic options. Both materials can also be tinted to provide enhanced UV protection and reduce glare. However, it’s worth noting that tinting might slightly affect the materials’ optical clarity, something that riders should consider.

Environmental Impact

In terms of their environmental footprint, both materials are recyclable, yet the recycling processes for each are quite different and may not always be readily available in certain areas. Polycarbonate can be recycled into other plastic items, a positive attribute indeed.

However, the process is more complex and requires specialized recycling facilities. On the other hand, acrylic can be more easily recycled, but it’s important to note that it is typically downcycled into products of lower quality. Therefore, while both materials can be recycled, the methods and results differ significantly.

Recommendations and Conclusion

Choosing between polycarbonate and acrylic for your motorcycle windshield ultimately depends on your specific needs and preferences. If safety and flexibility are your top priorities, and you don’t mind a higher price tag, a polycarbonate windshield is your best bet. If cost, clarity, and easy maintenance are more important, then an acrylic windshield would serve you well.
