ETFE Film (Ethylene-Tetrafluoroethylene Copolymer Film)

High-strength, lightweight ETFE film delivers exceptional chemical resistance, UV stability and thermal performance. Ideal for architectural and agricultural applications, it outperforms glass with 1% of the weight and superior recyclability.

Ethylene-Tetrafluoroethylene Copolymer Film (ETFE Film) is a high-performance crystalline fluoropolymer film characterized by a melting point range of 256~280℃, inherent self-extinguishing properties, and outstanding mechanical and chemical stability. As a member of the fluoropolymer family-alongside PTFE, FEP, and PVDF-it stands out for its balanced strength, flexibility, and cost-effectiveness, making it a preferred material for demanding industrial, architectural, and agricultural projects.

Features (F)
1.Material & Thermal PerformanceETFE film is a semi-crystalline fluoropolymer synthesized from ethylene and tetrafluoroethylene monomers, boasting a melting point of 256~280℃. Unlike traditional plastic films, it exhibits self-extinguishing behavior when exposed to open flames, eliminating the risk of flame spread without additional flame retardants.
2.Mechanical StrengthIt delivers industry-leading high-shear mechanical strength and unrivaled low-temperature impact resistance among fluoroplastics. From room temperature down to -80℃, the film maintains high impact strength without embrittlement, a critical advantage over brittle alternatives like glass or rigid PVDF sheets.
3.Chemical & Environmental StabilityETFE film features exceptional chemical inertness, resisting corrosion from acids, alkalis, organic solvents, and harsh industrial chemicals. It also offers excellent electrical insulation and radiation resistance, ensuring long-term performance in outdoor, high-radiation, or high-voltage environments.
4.Customizable SpecificationsOur ETFE film is available in standard and custom dimensions to meet diverse application needs. The core standard specifications include:| Thickness | Width | Length | Apparent Condition ||-----------|-------|--------|-------------------|| 200μ | 1250mm | 100-500m | Transparent, plated, colored; customizable size || 250μ | 1250mm | 100-500m | Transparent, plated, colored; customizable size |
 

Advantages (A)
1.Lightweight vs. Traditional MaterialsCompared to glass, ETFE film weighs only 1% of the same area of glass panels, significantly reducing structural load in architectural projects. This lightweight advantage also cuts transportation and installation costs by up to 70% compared to rigid FEP sheets or PVDF tubing systems.
2.Superior Durability & LongevityWith a service life of over 25 years in outdoor applications, ETFE film outlasts conventional greenhouse films by 5-10 times. Its UV stability prevents yellowing or degradation under prolonged sunlight exposure, maintaining 90% light transmittance over decades.
3.Eco-Friendly & RecyclableUnlike single-use plastic films, ETFE film is 100% recyclable. Recovered film can be reprocessed into new fluoropolymer products without performance loss, aligning with global sustainability goals for green construction and agricultural projects.
 

Benefits (B)
1.Architectural Applications: Cost & Efficiency GainsFor large-span structures like stadiums, museum domes, and parking lot awnings, ETFE film's lightweight property reduces the need for heavy steel support structures, slashing overall project costs by 30-40%. Its high light transmittance (up to 95%) also enhances natural lighting, lowering indoor lighting energy consumption by 20% annually.
2.Agricultural Greenhouses: Higher Crop YieldsAs a greenhouse covering material, ETFE film's optimal light diffusion and UV resistance promote uniform crop growth, increasing yields of high-value crops (e.g., fruits, vegetables) by 15-20%. Its low-temperature impact resistance ensures year-round use even in cold regions, eliminating the need for seasonal film replacements.
3.Industrial Applications: Reliable PerformanceIn industrial settings, ETFE film's chemical resistance and electrical insulation make it ideal for lining chemical tanks, insulating high-voltage equipment, and manufacturing flexible tubing components. Its radiation resistance also suits nuclear power plant applications where other fluoropolymers may fail.
 

Evidence (E)
The iconic British Millennium "Garden of Eden" project serves as a benchmark for ETFE film's architectural capabilities. This landmark structure, hailed as the "Eighth Wonder of the World," features four dome-shaped buildings covered entirely in our ETFE film. The film's 1% weight advantage over glass allowed engineers to design a ultra-lightweight support structure, while its recyclability and thermal insulation properties reduced the project's carbon footprint by 25%. To date, the ETFE film covering has maintained its structural integrity and optical performance for over 20 years, validating its long-term durability.
In agricultural applications, a 5-year field test conducted in northern China showed that greenhouses using our ETFE film achieved 18% higher tomato yields than those using conventional PE films, with 50% fewer maintenance costs due to its tear resistance and weather durability.
