PC window visors are known for their superior strength, flexibility, and heat resistance. Polycarbonate is up to 20–30 times stronger than acrylic, making it highly impact-resistant and safe during installation or shipping.
When choosing window visors (also known as rain guards, wind deflectors, or vent visors), the material is one of the most important factors that determine durability, appearance, and long-term performance.
The two most common materials in the market are PC (Polycarbonate) and Acrylic (PMMA).
Many buyers are unsure which option is better.
This guide explains the differences clearly and helps you choose the right product for your market.
⭐ 1. PC (Polycarbonate) Window Visors – Premium, High-Strength Choice
Polycarbonate is known as “bulletproof material” because of its extremely high impact resistance.
It is widely used in high-quality window visors, aircraft windows, safety shields, and OEM automotive parts.
Key Advantages of PC Window Visors
✔ 1. Superior Strength & Flexibility
PC is 20–30 times stronger than acrylic.
- Highly impact-resistant
- Can bend without cracking
- Does not turn white when flexed
- Safer during installation and shipping
Perfect for harsh environments and high-end aftermarket products.
✔ 2. Excellent Heat & Cold Resistance
PC performs well from -40°C to 130°C.
- No warping in hot sunlight
- No cracking in cold weather
- Better resistance to UV and long-term aging
Ideal for countries with strong sun (USA, Australia, Middle East).
✔ 3. Injection-Molded for Better Fit
Most premium visors use injection molding with PC material.
Benefits include:
- Perfect fit to the car frame
- Smoother edges
- Stronger structure
- OEM-style appearance
✔ 4. More Premium Look
PC has deeper, glossier color and a higher-quality finish.
It looks closer to original factory parts.
❗ PC Disadvantages
- Higher cost
- Higher requirements for molds and production
- Generally positioned in the mid-to-high-end market
⭐ 2. Acrylic Window Visors – Affordable, Economic Option
Acrylic (PMMA) is a hard plastic commonly used in low-cost window visors.
Advantages of Acrylic Window Visors
- Lower production cost
- Good surface hardness (scratch-resistant)
- Good clarity and basic appearance
Suitable for price-sensitive markets like Southeast Asia, South America, Africa.
Disadvantages of Acrylic
✘ 1. Brittle and Easy to Crack
Acrylic is rigid but fragile:
- Can crack during bending
- Turns white when flexed
- More likely to break during shipping or installation
✘ 2. Poor High-Temperature Resistance
Under strong sunlight, acrylic is more likely to:
- Warp
- Turn yellow
- Age faster
Cold environments also increase the risk of cracking.
✘ 3. Less Premium Appearance
The gloss and depth of color are not as good as PC.
