 Product Advantage

Core Advantages & Technical Features of Butyl Film
Ultra-Wide Temperature Resistance for Extreme Environments
Compliant with GB/T 41944-2022 standard, it withstands a temperature range of -40℃ to 180℃. It remains non-flowing and non-deformed at 180℃ and maintains flexibility without cracking at -40℃, far exceeding the industry’s typical -30℃ to 120℃ range. Ideal for high and low temperature resistant butyl film applications in outdoor construction, marine vessels, and new energy equipment across diverse climates.

Superior Damping & Noise Reduction Performance
With a damping coefficient ≥0.20 (tested at 20℃), it achieves over 40% vibration and noise attenuation, effectively reducing operational noise from machinery, automobiles, and home appliances. In automotive bodies, it significantly weakens engine vibration transmission, enhancing riding comfort— a core strength of vibration damping and noise reduction butyl film.

Eco-Friendly, Non-Toxic & Compliance-Certified
Adopting a solvent-free formula, it has a formaldehyde emission ≤0.02mg/m³ and VOC content well below EU RoHS and REACH limits. With an odor level ≤3, it releases no toxic gases, holding food-contact and automotive interior environmental certifications. Suitable for enclosed scenarios like refrigerators and car interiors, it exemplifies eco-friendly non-toxic butyl film.

High Adhesion & Self-Fusing Sealing for Multi-Substrates
Boasting a peel strength ≥0.3kN/m, it bonds firmly to metal, glass, concrete, and plastics without primers. Featuring 800% elongation and excellent self-fusing properties, it automatically fills gaps up to 3mm, adapting to substrate thermal expansion and contraction. With a bonding lifespan exceeding 20 years, it solves common issues of peeling and cracking in traditional sealing materials.

Flame Retardant, Corrosion Resistant & Long-Lasting Protection
Flame-retardant variants have an oxygen index ≥30% (flame-retardant grade), enhancing fire safety. Resistant to UV rays, acids, alkalis, and salt spray, it passes 500-hour salt spray tests without rust. Suitable for long-term protection of pipelines and steel structures, it embodies the technical strength of long-lasting protective butyl film.

 Product Uses

Core Application Scenarios of Butyl Film
Building Sealing & Waterproofing
Ideal for metal roof laps, door/window frame gaps, and basement construction joints. It bonds firmly to concrete, metal, and other substrates, resists water vapor penetration, and adapts to thermal expansion/contraction, extending the service life of building seals.

PV Module Encapsulation
Used for edge sealing of PV modules, it forms a barrier with low water vapor transmission rate (≤0.7 g·m⁻²·d⁻¹), delaying module degradation. Compatible with double-glass and perovskite modules, it enhances PID resistance and meets 1500V high-voltage insulation requirements for long-term outdoor stability.

Automotive & Transportation Infrastructure
Seals automotive doors, sunroofs, and body joints, providing waterproofing and vibration/noise reduction. Also fills highway expansion joints and bridge bearing gaps, buffering vibrations and preventing rainwater erosion in complex transportation scenarios.

Industrial Equipment & Pipeline Protection
Wraps chemical, gas, and water pipeline joints to isolate air and moisture, preventing corrosion. Seals industrial cooling tower seams and electrical cabinet gaps, achieving dustproof and waterproof protection for internal components in harsh environments.

Marine & Home Appliance Sealing
Suitable for sealing ship decks and cabin doors/windows, resisting salt spray and UV radiation in marine environments. Used in refrigerators, water purifiers, etc., it is eco-friendly, odorless, and compliant with food-contact safety standards for enclosed appliance gaps.

 Product Operate Guide

How to Use Butyl Film: Operation Guide Clean and dry the substrate surface (remove dust, oil, and moisture) for optimal adhesion. Cut the butyl film to the required size using scissors or a utility knife. Peel off the release liner, align it with the target area, and press firmly from the center to the edges to eliminate air bubbles. For gaps >1mm, layer appropriately; avoid stretching during application. For detailed steps, safety precautions, and troubleshooting, download our Butyl Film Operation Manual PDF.

 FAQ

Frequently Asked Questions (FAQs) About Butyl Film

1. What substrates is butyl film compatible with?

A:  It bonds firmly to metal, glass, concrete, plastics, and wood without primers. Ensure surfaces are clean, dry, and free of oil/dust for optimal adhesion.

2. Can it be used outdoors for long-term exposure?

A: Yes. With excellent UV, weather, and aging resistance, it maintains performance for over 15 years outdoors, adapting to -40℃~180℃ temperature ranges.

3. How to handle gaps larger than 3mm?

A: Layer the film appropriately or use a thicker variant. Press firmly to ensure full contact with the substrate; avoid stretching to prevent adhesion failure.

4. Is it resistant to chemicals or salt spray?

A:  It withstands acids, alkalis, and salt spray. Passing 500-hour salt spray tests, it’s ideal for marine, chemical, and outdoor corrosive environments.

5. Can it be applied in cold or humid conditions?

A:  It performs well at low temperatures (-40℃), but substrates must be dry. Avoid application on wet surfaces as moisture may affect long-term adhesion.
