When make a comparion of PVB glass vs EVA glass, we need to know what is laminated glass? – Laminated glass, also called VSG glass, known as safety glass, is the strongest and most durable product among various glass products in the world. As the name suggests, laminated glass is composed of multiple layers of glass, such as double-layer glass, triple-layer glass, and quadruple-layer glass, and more.
In addition, apart from glass, the interlayer film in the middle of the glass is also important. There are usually three types of interlayer films: EVA, PVB, and SGP. With so many choices, what are their differences? Today, let me first talk about PVB glass vs EVA glass.
1-Belief Introduction
What is PVB glass?
PVB glass also called PVB sandwich glass, which is widely use for different building project and automotive industry. They often use two, three or four glass panels with PVB combination, PVB stands for Polyvinyl butyral, it’s a transparent plastic material that possesses excellent adhesion, toughness, and clarity.
Because PVB is sandwiched between layers of glass. When the glass breaks, the PVB layer holds the broken pieces together, reducing the risk of injury from sharp shards. PVB film glass also offers other benefits, such as sound insulation and UV protection, making it a popular choice for applications such as architectural glazing, safety glass for buildings and automotive windshields.
What is EVA glass?
EVA glass is another kind of sandwich glass, which often use for interior jobs because its have, because its special performance, can combine different materials, such as metal mesh laminated glass, fiber glass, or carved laminated glass and rattan glass, then reach a very good deocrative effects.
The EVA glass same as PVB glass, also have a safety performance, when glass breaking, the break pieces will be fixed on the films. EVA interlayer glass allows for various decorative options, making it popular for use in artistic and design-oriented projects.
2-Features of PVB glass vs EVA glass
Polyvinyl butyral (PVB glass) and ethylene vinyl acetate (EVA glass) are two common interlayer materials used in the production of laminated glass. The following is a comparison of the characteristics of PVB glass and EVA glass:
1-Strength and Durability
- PVB glass offers excellent strength and durability. It can withstand impact and helps hold glass fragments together upon breakage, enhancing safety.
- EVA glass also provides good strength and durability. It is known for its excellent adhesion properties, resulting in strong bonds between glass layers. So that’s why its can laminating different materilals in a very good conditions.
2-Clarity
- PVB interlayers for glass typically offer high optical clarity, allowing for clear visibility through the glass.
- EVA interlayers for glass also provide good clarity, but some formulations may have slightly lower optical clarity compared to PVB.
3-Processing
- PVB glass requires a longer and more complex lamination process involving heat and pressure to bond the glass layers together effectively.
- EVA glass typically have a lower melting point than PVB, which allows for faster lamination cycles. EVA can also bond well with different types of glass and materials.
4-UV Protection
- PVB glass offer an excellent level of UV protection, helping to reduce UV radiation transmission through the glass.
- EVA glass may provide less UV resistance compared to PVB, suggest using the interior.
5-Sound Insulation
- PVB laminated glass offers good sound insulation properties, helping to reduce noise transmission through the glass. Especially Acoustic PVB widely controls the noise in the buildings.
- EVA laminated glass may provide similar or less sound insulation compared to PVB, depending on the specific formulation and thickness.
6-Adaptability
- PVB interlayer glass are commonly used in a wide range of applications, including architectural glazing, automotive windshields, and safety glass.
- EVA interlayer glass are versatile and suitable for various applications, including architectural, decorative, and solar panel encapsulation. Mostly use for interior jobs.
