What materials are used for windshield seals?
Windshield seals come in different materials suitable for different vehicles. The most common materials include:
Gomma EPDM
- The most widely used windshield sealing material.
- Excellent resistance to UV rays, ozono, ed temperature estreme.
- Soft and durable, maintaining a seal for a long time.
PVC
- Often used in combination with foam or metal reinforcement materials.
- Economical and weather-resistant.
- It is less flexible than EPDM, so it is sometimes used for trim sections rather than full seals.
TPV
- Combines the characteristics of rubber and plastic.
- Resistant to aging, prodotti chimici, e agenti atmosferici.
- Easier to manufacture into complex shapes.
Gomma silicone
- Resistenza ad alta temperatura, often used in high-performance vehicles.
- Very flexible and durable, but more expensive.
Nitrile Rubber

Come scegliere la guarnizione in gomma per parabrezza giusta?
If you want to protect your car from water, vento, and noise, choosing the right windshield rubber seal is crucial.

- Consider the material: Rubber seals come in many materials, such as EPDM, PVC, TPE, and natural rubber. EPDM and TPE are generally the best because they last longer, are resistant to sunlight, and are less prone to cracking. PVC and natural rubber are more susceptible to wear and tear in hot or cold weather.
- Check the size and shape: Ensure the seal’s width, spessore, and shape are suitable for your vehicle. Some are U-shaped, P-shaped, or H-shaped. A proper fit prevents water leakage and reduces wind noise while driving.
- Check weather resistance: A good seal should withstand high temperatures, cold, rain, and sunlight. Check if the seal has been tested for aging, Resistenza UV, and temperature variations.
- Original equipment or custom-made: Original equipment seals are manufactured by the car company, so the quality is usually more consistent. Custom or aftermarket seals can perfectly fit your vehicle and offer more options in size and shape. If you’re buying in bulk, it’s recommended to try a sample first to ensure a proper fit.
By considering these factors, you can choose a windshield rubber seal that fits well, is durable, and keeps your vehicle safe and quiet while driving. If you are unsure how to choose, Si prega di contattarci. We are a professional seal manufacturing factory.
