Product Specification

Product Overview

The Westglass Automotive Window PVB Materials Laminated Film Series is a high-performance polymer film made from polyvinyl butyral (PVB) resin plasticized with additives and extruded into sheets. Standard thicknesses include 0.38mm and 0.76mm, with customizable options like 0.5mm, 1.14mm, and 1.52mm. Using a 120°C–140°C high-temperature/high-pressure lamination process, it bonds two or more glass panes into a composite structure, delivering superior optical stability, weather resistance, and functional integration. Widely used in building curtain walls, automotive glass, photovoltaic modules, and high-end industrial applications, it serves as a core material for multi-scenario glass processing.

Core Features

1.     Active Safety Protection

• Explosion-Proof & Impact Resistance:
  • PVB film boasts elongation at break ≥200% and adhesive strength ≥5N/mm², absorbing 80%+ of impact energy during collisions. Shattered glass fragments remain bonded to the film, preventing injuries—compliant with international safety standards. For buildings, it withstands typhoons and hailstones, reducing falling glass risks.
• Secondary Damage Prevention:
  • 0.76mm thickness for automotive windshields maintains glass integrity post-breakage; 1.52mm thick film for architectural use delays forced entry, enhancing security in banks and museums.

2.     Stable Optical Performance

• High-Transparency & Low Distortion:
  • Visible light transmittance ≥85% (clear type), haze ≤0.7%, ensuring distortion-free views with color fidelity ≥95%. Automotive-grade film is HUD-compatible, eliminating ghosting; architectural-grade film preserves natural light for premium office and commercial spaces.
• Customizable Light Control:
  • Offers 30%–90% transmittance customization. Dark tints (gray/blue) balance sun shading and privacy, ideal for building curtain walls and automotive privacy glass.

3.     Acoustic & Thermal Management

• Intelligent Thermal Blocking:
  • Nano infrared-blocking particles block 90%+ of near-infrared rays, reducing heat transfer by 30% in buildings (25% lower AC energy use) and lowering car cabin temperatures by 3–5°C in summer—boosting EV range by reducing AC load.
• Full-Spectrum Noise Reduction:
  • 0.76mm film dampens 25dB of mid-low frequency noise and 20dB of high-frequency noise, achieving ≤50dB in car cabins and ≤35dB in buildings for quiet environments.

4.     All-Weather Durability

• Extreme Environment Resistance:
  • Passes -40°C–85°C thermal cycles (1000 cycles without failure) and 1000-hour UV aging tests, with no yellowing (ΔE≤3), delamination, or embrittlement. Maintains performance in high humidity (RH≥95%), salt spray, and strong UV—10+ years lifespan for architectural use, matching vehicle design cycles (10 years) for automotive.
• Eco-Friendly Certification:
  • Compliant with global environmental standards (RoHS, REACH), free of harmful substances.

Packaging & Storage

1.     Professional Packaging:

• Vacuum-sealed in aluminum foil (VCI Class A moisture protection), standard rolls: 100m/200m. Custom width (500mm–3000mm), secured with wooden pallets and anti-collision foam for damage-free transport.

2.     Storage Requirements:

• Store in cool, dry, dark environments (18°C–23°C, 20%–25% humidity). Use within 24 hours after opening; reseal unused film to prevent moisture/high-temperature exposure.

Precautions

1.     Maintenance Tips:

• Inspect glass seals every 2 years in high-UV areas to prevent edge aging. Avoid acidic cleaners on architectural glazing.

2.     Processing Guidelines:

• Ensure glass surface cleanliness (oil residue ≤0.1mg/㎡). Adjust lamination parameters by thickness (pressure 8–12bar, time 15–30 minutes) to avoid bubbles or uneven bonding.

Application Scenarios & User Value

1.     Architecture

• Super high-rise curtain walls: Typhoon resistance + noise reduction for iconic buildings.
• Airport noise barriers: Blocks aircraft noise for adjacent residential/commercial areas.

2.     Automotive

• EV sunroofs: 0.38mm lightweight film for heat insulation and explosion-proofing, enhancing battery efficiency.
• Commercial vehicle side windows: 30% transmittance gray tint for privacy and 99% UV blocking.

3.     Renewable Energy

• PV module encapsulation: Weather resistance + ≥70% transmittance, ≤0.5% annual efficiency degradation.
• Energy storage protection: Impact resistance + fire-resistant coating for safe operation in extreme conditions.
