Product Specification

Product Overview

The Westglass High-Strength PVB Materials Laminated Film Series (polyvinyl butyral interlayer film) is a high-performance polymer bonding material designed for architectural laminated glass systems. Through a 120°C–140°C high-temperature and high-pressure lamination process, it securely bonds glass panes with PVB film to form a three-layer "glass-PVB-glass" composite structure. This structure delivers exceptional safety, superior noise reduction, and significant energy efficiency—making it ideal for applications like curtain walls, skylights, and window systems, and an indispensable core material in modern architectural glass processing.

Core Advantages

1.     Comprehensive Safety Protection

• Explosion-Proof & Impact Resistance:
  • Strong molecular bonding absorbs 80%+ of impact energy during typhoons or hail, keeping shattered glass fragments attached to the film and preventing injuries.
• Wind & Earthquake Resilience:
  • With elongation at break ≥200%, it distributes wind and seismic forces, slowing glass fracture to provide critical evacuation time for high-rises and seismic zones.

2.     Innovative Energy Efficiency

• Thermal Performance Optimization:
  • Combined with Low-E coatings or nano-infrared barriers, it blocks 75%–90% of solar infrared radiation, reducing summer AC energy use by 30% and winter heat loss by 20%—boosting building energy efficiency by 15%–30%.
• Full-Spectrum UV Protection (Customizable):
  • Polymer UV absorbers block ≥99% of 200–400nm UV rays, extending the lifespan of furniture, flooring, and artworks by 50%+ by preventing photodegradation.

3.     Broadband Noise Reduction System

• Acoustic Enhancement:
  • Viscoelastic damping properties of PVB film efficiently block mid-low frequency noise (traffic, machinery), creating quiet interiors—especially for buildings near airports or busy roads.
• Customizable Soundproofing:
  • Tailor film thickness and layer combinations to meet diverse noise control needs for residences, hospitals, and schools.

4.     Optical Clarity & Design Versatility

• High-Transparency & Low Distortion:
  • ≥85% visible light transmittance (clear type), haze ≤0.7%—ensuring abundant natural light with true-to-life color representation and no optical distortion or white-edge defects.
• Aesthetic Flexibility:
  • Available in clear, frosted, colored (gray, blue, green), and printed designs to match modern minimalism or enhance facades with gradient colors/artistic textures for commercial complexes and historic renovations.

5.     Eco-Durable Performance

• Extreme Environment Resistance:
  • Passes -40°C–80°C thermal cycles and 1000-hour tested (85°C/RH95%) with no yellowing (ΔE≤3) or delamination, maintaining stable adhesion in high-salt and strong-UV environments for 10+ years with low maintenance costs.
• Green Compliance:
  • Lead-free production, zero formaldehyde, and no harmful VOC emissions—certified to international environmental standards for safe indoor air quality.

Application Scenarios

1.     Curtain Walls & Skylights

• High-Rise Curtain Walls: 1.14mm PVB film enhances wind resistance and UV protection, balancing safety and aesthetics for office towers and commercial complexes.
• Large Skylights: PVB-laminated glass with Low-E coatings achieves 90% light transmittance while reducing heat gain, ideal for airport, transit, and convention center atriums.

2.     Education & Healthcare

• School Windows: 0.76mm soundproof film reduces traffic noise for quiet classrooms, while explosion-proof properties protect students and staff from accidental impacts.
• Hospital Partitions: UV-blocking films safeguard medical equipment and patients from light damage, while noise reduction enhances privacy and diagnostic comfort.

3.     Commercial & Public Buildings

• Commercial Complexes: Dark-tinted thermal films cut curtain wall energy costs, while custom colors boost brand identity for a dual focus on efficiency and design.
• Banks/Jewelry Stores: 1.52mm ballistic-enhanced film with multi-layer glass creates anti-smash, anti-penetration barriers for high-security requirements.

4.     Historic Renovations

• Heritage Buildings: Clear, high-transparency PVB film preserves original glass aesthetics while enhancing impact resistance and UV protection for historic facade upgrades.
• Retrofit Projects: 0.38mm ultra-thin film improves noise and heat insulation without altering original window structures, perfect for cost-effective renovations.
