Product Specification

Product Overview

The Westglass EVA (Ethylene-Vinyl Acetate Copolymer) Film is a core encapsulation material for manufacturing PDLC smart dimming glass, specifically engineered for laminated glass processes. Using high-temperature and high-pressure lamination technology (110℃–150℃), it seamlessly bonds PDLC liquid crystal films with glass substrates, eliminating risks of detachment or delamination in extreme environments and ensuring structural stability.

With 8 years of production and sales experience, our EVA film ensures the reliability of dimming glass in smart switching, safety protection, and long-term use, thanks to its high transparency, strong adhesion, and excellent weather resistance. It is a critical component for enhancing product performance.

Core Advantages

1. Superior Optical Performance

• High Light Transmittance: Ensures unobstructed, distortion-free light in the clear state of PDLC glass, with uniform light scattering in the frosted state for delicate visual effects. No white edges or haze interference from side views, maintaining clarity from all angles.
• Low Haze: Film haze ≤1.5%, minimizing light refraction and ensuring sharp visuals for HD projection requirements.

2. Exceptional Adhesion & Safety Protection

• Permanent Bonding: Forms an integrated structure with glass and LCD films after high-temperature/high-pressure curing, with peel resistance >30N/cm² to prevent delamination and bubbling.
• Explosion-Proof & Impact-Resistant: High bonding strength enhances impact resistance. Even if glass breaks, EVA film securely holds fragments, preventing injuries and complying with GB/T 15763.3 safety glass standards.

3. Weather Resistance & Stability

• Wide Temperature Adaptability: Passes -40℃–85℃ extreme temperature tests and UV aging validation, suitable for outdoor exposure, high humidity, and other harsh environments. Maintains no yellowing or corrosion over time, extending dimming glass lifespan.
• UV Aging Resistance: Contains UV absorbers to block 99% of UV rays, preserving LCD film performance and extending dimming glass lifespan to 10+ years.

4. Eco-Friendly & Energy-Efficient

• Low-Energy Process: Cures at low temperatures (110℃–150℃), reducing production energy consumption and aligning with green manufacturing standards.
• No Harmful Substances: Complies with EU RoHS standards, non-toxic, and emits no VOCs during lamination—ideal for hospitals, homes, and other eco-sensitive environments.

5. Flexible Adaptation & Easy Processing

• Ultra-Thin Design (≤0.3mm thickness): Supports precise lamination on curved, irregular glass, and flexible substrates, meeting customized needs for car sunroofs, curved curtain walls, etc.
• Simple Cutting Process: Compatible with one-step or autoclave production, significantly reducing processing costs and time.

Comparative Advantages (VS PVB Laminated Film)

Typical Application Scenarios

• Smart Architecture: Curtain walls, windows, skylights—replace traditional blinds for dynamic light regulation.
• Transportation: Car sunroofs, subway windows—enhance privacy and energy efficiency.
• Commercial Spaces: Conference room partitions, hotel bathrooms—switch between clear and frosted states with one touch.
• Home Upgrades: Bathroom glass, home theater screens—combine safety, privacy, and tech-aesthetic design.
