Ethylene Vinyl Acetate (EVA) Film & Sheet
What is EVA Film?
Ethylene-vinyl acetate (EVA) film is a type of plastic film made from the copolymerization of ethylene and vinyl acetate.
EVA stands for Ethylene Vinyl Acetate. It is a flexible and durable polymer. It has a semi-crystalline structure. EVA is composed of two monomers: ethylene and vinyl acetate:
- Ethylene: It is a hydrocarbon. It is derived from natural gas or petroleum. This component contributes to the toughness & weather resistance of EVA.
- Vinyl Acetate: It is produced by the reaction of ethylene with acetic acid and oxygen. This component imparts flexibility & transparency to the EVA polymer.
Why Choose EVA Film for Your Needs?
EVA allow industries to mainly benefit from the following combination of properties :
Flexibility and Elasticity of EVA Film
Recent advancements have enabled the production of high-performance EVA film. These solutions exhibit a flexibility range of 30 to 70 Shore A, and provide:
- superior surface clarity,
- remarkable adhesion to substrates like glass and metal,
- exceptional tear and puncture resistance.
Combination of High Transparency with Impact resistance
Crystal-clear EVAs are available with very good hardness. This characteristic allows the use of EVA in the:
- glass lamination and solar panels, or
- injection molding of technical, aesthetic parts, where transparency at a thickness as high as 6mm can be achieved.
UV Resistance
EVA films ensure durability and longevity for your products. They show excellent resistance to weathering and UV radiation, thus maintaining their properties over time.
EVA film has precisely the right property profile and versatility to make it the material of choice for various applications. For both indoor and outdoor uses, manufacturers can rely on EVA film’s high adhesive strength and UV stability.
Other Benefits of EVA Film
- Effective bonding to various materials for versatility
- Resilience to oils, greases, and numerous solvents
- Good flexibility under varying environmental conditions
- Robust weather and high-energy radiation resistance
What Are the Key Applications of EVA Film?
EVA film’s unique properties make it suitable for a wide range of applications across various industries.
Photovoltaic Solar Panels
To meet the current trends in solar panel manufacturing for efficiency and durability, EVA film offers a reliable encapsulant solution for photovoltaic modules. Additionally, it provides a cost-effective alternative when compared to other encapsulant materials, such as PVB and TPO. Other benefits include:
- High transparency and UV resistance
- Excellent adhesive properties
- Strong mechanical support
- Provides thermal stability
Glass Lamination
The construction market demands strength and durability of the materials used. One of the most critical applications are safety glass laminates used for buildings.
Ethylene Vinyl Acetate offers outstanding flexibility, impact resistance, and adhesive properties across a wide range of temperatures.
Special formulations and additive packages allow for the design of clear, tinted, or even smart (with embedded sensors) glass laminates.
Packaging
Thanks to its unique combination of excellent flexibility, strong adhesive properties, and resistance to environmental factors, EVA film is the material of choice for many packaging applications.
- Exceptional sealability
- High clarity
Agricultural Industry
The agricultural market demands strength and durability of the materials used. One of the most demanding applications is the use of EVA film on agricultural products. Ethylene Vinyl Acetate (EVA) film offers outstanding flexibility, weather, and tear resistance across a wide range of climates. Special formulations and additive packages allow for the design of flexible, durable, and high-clarity films suitable for various agricultural applications.
Is EVA Plastic Environmentally Friendly?
EVA film is biodegradable & can be recycled. Other benefits offered by EVA film over PVC films include:
- Environmental friendliness
- EVA film is crack resistant while other films can degrade over time
- More flexible and lightweight than PVC films
- In solar panels, it is accepted as an effective encapsulant. This is because EVA film grades do not use harmful additives that can cause environmental damage or product degradation.
EVA films used in packaging, automotive, and solar energy applications effectively improve durability and performance. In solar panels, EVA film products enhance energy output, because they are more efficient than alternative encapsulant materials.ed as recycling other plastics like PET. Improved recycling processes could enhance its environmental friendliness.
