Glass Double Laminating Machines have a significant importance in fabricating specialized laminated glass products for use in the construction, automotive and interior design industries. To be able to achieve the best results, one must choose the best lamination materials. This article discusses the commonly used top lamination materials on glass double laminating machines and their advantages and applications. 

1. Polyvinyl Butyral (PVB) Film

Amongst the laminated glass PVB film is one of the most frequently used interlayer materials. It allows for a strong bond to be formed between the glass layers as well as providing additional strength. PVB also adds a protective layer that holds glass pieces together and prevents them from scattering during a breakage. Its soundproofing characteristics plus UV blocking properties enable its usage in architectural applications like building facades or windshield panels of cars. 

2. Ethylene Vinyl Acetate (EVA) Film

EVA film is a suitable interlayer that can be used on decorative glass and photovoltaic interleaves. It can also resist moisture and withstand harsh conditions. EVA is commonly employed for laminated glass panels that incorporate fabrics or other decorative features, and offers as well great optical clarity and properties of firm adhesion.

3. SentryGlas Interlayer

SentryGlas has impressive properties being an ionoplast interlayer. It boasts five fold strength and up to a hundred fold rigidity of other inter layers made of PVB. As such PVB interlayers. PVB Lungarzo et al. concluded that SentryGlas can be used for applications where over head glass installations such as overhead windows, glass railings as well as wind resistant glass windows. 

4. Thermoplastic Polyurethane (TPU) Film

TPU film is widely used when flexible laminates resist impact due to their elastic properties. The material is often seen being used in laminated windshield for impact absorbing systems in vehicles. TPU materials also possess decent levels of optical clarity so these films can be used with non flat surfaces such as curved glass. 

5. Colored PVB and Decorative Films

For PVB manufacturers, colored films and decorative interlayers are available to augment the aesthetic values of the laminated glass. Such films let architects and designers design glass facades, partitions, and interiors of tempered glass products of m various colors and patterns with the withstand high loads of laminated glass. 

6. Liquid Resin Interlayers

Liquid resin interlayers are used to fabricate glass samples on request for specific applications. The process consists also in laminating laced sheets followed by curing the resin. This technique is appropriated for producing thick laminated glass panes applied in aquariums, glass balconies, and bullet and knife proof laminated product.

7. Polycarbonate for Hybrid Lamination

Polycarbonate sheets are occasionally utilized in combination with glass in hybrid lamination processes in certain situations. These materials are useful in laminate designs and make it possible to manufacture glass-polycarbonate laminates with very low weight for security purposes. Polycarbonate aids in noise control and the design of energy conserving windows as well.

In deciding which lamination material to use in a glass double laminating machine, the initiation of the process as well as the performance requirements should be factored. Most of these materials have specific applications and their varying compositions include safety PVB films, and decorative and structural SentryGlas and EVA materials among others. The use of these materials is well defined so that the participants can get maximum satisfaction in the production of quality laminated glass products.
