Product Specification

Product Overview

The Westglass PVB Materials Laminated Film Series (polyvinyl butyral) is a high-performance polymer material engineered for automotive laminated glass. It bonds two or more glass panes under high temperature and pressure, creating strong, safe composite window glass with superior impact resistance and structural integrity.

Prioritizing safety, our automotive PVB films integrate functions like heat insulation, noise reduction, and optical optimization, making them ideal for windshields, side windows, and sunroofs. They deliver both protective safety and functional enhancement for modern vehicles.

Core Advantages

1.     Superior Safety Performance

• Impact Resistance & Anti-Shattering:
  • Absorbs impact energy to prevent glass fragmentation; shattered pieces adhere to the PVB film, reducing injury risks—far safer than standard tempered glass.
• Anti-Theft Protection:
  • Maintains glass integrity even when struck, deterring break-ins and enhancing vehicle security.

2.     Efficient Thermal & UV Protection

• Infrared Blocking:
  • Reduces solar heat penetration, lowering cabin temperature and air conditioning load for energy savings.
• 100% UV Blocking:
  • Absorbs harmful UV rays to protect passengers’ skin and vehicle interiors from fading and aging.

3.     Optical Clarity for Safety

• High Transmittance:
  • Clear, colorless design ensures unobstructed driver vision with no white-edge interference, aligning with the aesthetic demands of luxury vehicles.

4.     Durability & Eco-Friendliness

• All-Weather Resistance:
  • Passes -40°C–85°C temperature tests and UV aging validation, resisting moisture, oil, and yellowing for long-term stability in sunroofs and side windows.
• Safe & Sustainable:
  • RoHS-compliant, free of formaldehyde and heavy metals—safe for passengers and the environment.

5.     Multi-Functional Integration

• Noise Reduction:
  • Dampens external noise by 20–30 dB, enhancing in-cabin tranquility during drives.
• Lightweight Design:
  • Available in 0.38mm/0.76mm thicknesses to balance strength and weight reduction for modern vehicle engineering.

Application Scenarios

1.     Windshields:

• Compatible with HUD (head-up display) technology, eliminating ghosting for safer driving.

2.     Side Windows & Sunroofs:

• Enhances noise and heat insulation while improving privacy and comfort.

3.     New Energy Vehicles:

• Reduces energy consumption to extend battery range, aligning with eco-friendly mobility goals.

Packaging & Storage

• Packaging: Vacuum-sealed aluminum foil rolls (100m/200m standard), with customizable width and thickness.
