EVA (Ethylene-vinyl acetate) interlayer is a polymer film that is used to create laminated glass. It is known for its excellent mechanical, optical, and adhesive properties, making it a popular choice in various industries.
EVA interlayer has outstanding optical properties such as haze, clarity, and UV blocking. Haze refers to the light scattering within the material, which can affect the visibility of objects through the material. EVA interlayer has excellent haze properties, which means it has low haze, making it suitable for applications that require high optical quality. However, it’s important to note that the haze of EVA interlayer can be affected by the manufacturing process. For instance, if the EVA interlayer is not properly cured during the laminating process, it can result in haze issues. The thickness of the EVA interlayer can also affect the haze of the laminated glass. Generally, EVA interlayers come in thicknesses ranging from 0.38mm to 1.52mm. Thicker interlayers provide better soundproofing and impact resistance but may affect optical clarity, including haze.
If you are experiencing haze issues with your EVA laminated glass, it might be due to improper manufacturing or incorrect thickness of the EVA interlayer. It’s recommended to ensure that the EVA interlayer is properly cured and that the correct thickness is used for your specific application. If the issue persists, it might be worth consulting with a glass manufacturer or a professional in the field to investigate further.
