Why Choose Fusun Automotive PVB
Superior safety, optical clarity and long-lasting durability for windshields, panoramic roofs and vehicle windows.
Safety & Security
High Impact Resistance: Effectively absorbs impact energy to prevent glass penetration.
Optimized Adhesion Strength: Provides stable and appropriate bonding to the glass, ensuring that shattered fragments remain firmly adhered to the PVB film upon breakage—preventing dangerous splintering—while allowing controlled deformation under stress without tearing.
Test Standards: ISO 12543-3 (ball drop impact and penetration tests), impact hammer test, ECE R43 headform impact test, and anti-penetration test.
Excellent Optical Performance
High Light Transmittance: Typically ≥ 90% (mandatory regulatory requirement for front windshields).
Low Haze: Generally ≤ 1%, ensuring clear driver visibility.
Minimal Optical Distortion: Thickness uniformity tolerance ≤ ±0.02 mm to avoid visual distortion.
Test Standards: GB/T 2410, ISO 13837.
Durability & Weather Resistance
UV Resistance: Blocks ≥ 95% of UVA and ≥ 99% of UVB radiation.
Thermal Stability: Withstands extreme temperature cycling from –40°C to +85°C.
Humidity and Heat Resistance: Resists yellowing, bubbling, or delamination during long-term use.
Anti-Yellowing Formulation: Enhanced with UV absorbers and antioxidants (e.g., BHT).
Test Standards: GB/T 16422.3 (UV aging), SAE J1960.
Environmental and Health Compliance
Low VOC Emissions: Meets in-cabin air quality standards (e.g., GB/T 27630).
Free of Heavy Metals: Compliant with RoHS and other environmental directives.
Special Functional Variants
Acoustic PVB: Incorporates a sound-damping layer to reduce cabin noise by 3–5 dB.
Solar Control / IR-Reflective PVB: Designed for energy-efficient vehicles to enhance thermal insulation.
