Non Autoclave PVB, SGP, and EVA Laminating Machines: Characteristics, Applications, and Comparative Analysis

In the glass laminating industry, non autoclave laminated glass machines with PVB, SGP, and EVA films are now a popular choice. These films are of various types and are utilized for various purposes. How do you determine which film to utilize for laminating glass?Next, I will share with you the differences between these three in detail to help you do your work better. ​

PVB-based non autoclave lamination machines

PVB is among the most widely used interlayer films in glass lamination. Autoclave free pvb laminating machines are preferred because they have the ability to produce laminated glass with better optical clarity and impact resistance. The high adhesion strength of PVB gives a strong bond between glass layers.

In the automotive industry, these laminate machines are utilized in large quantities. For example, most windshields of automobiles are made with PVB films in non autoclave lamination machines. The laminated glass produced can efficiently withstand the have an impact on small stones on the avenue and protect the passengers inside the car. High optical clarity of PVB laminated glass is essential to allow the driver to have a clear view.

In architectural applications, PVB laminated glass is used in curtain walls. Not only does it play a protecting role against breakage of glass, but it also possesses suitable sound insulation characteristics, blocking exterior noise from getting into the building. At the price end, non autoclave lamination machines for PVB are quite cost-effective. Raw material cost of PVB film is in the middle level, and the processing technology is relatively mature, which is favorable for large-scale production in general applications.

SGP-based non autoclave lamination machines

SGP is a relatively new high-performance interlayer film. SGP-based non autoclave lamination machines are well known for their laminated glass with high strength and durability. The molecular structure of SGP gives it high shear strength.

This makes SGP-based machine laminated glass highly resistant to high forces.

For example, in high-security environments such as bank vaults and high-security establishments, SGP laminated glass is the most favored. It is more resistant to bullet penetration and forced entry than PVB laminated glass.

SGP laminated glass is also used in building facades in seismic areas. Because of its superior strength, the glass remains intact during earthquakes and minimizes the risk of glass breakage and subsequent falling to injure people and property.

However, SGP non autoclave lamination machines are relatively more expensive. The manufacturing cost of SGP film is relatively higher due to its complex manufacturing process and use of specialized raw materials. However, considering its super performance under high-security and high-stress conditions, the high price is justified for the projects involved.

EVA-based non autoclave lamination machines ​

EVA is a universally usable interlayer film and EVA-based non autoclave lamination machine is suitable to a wide range of applications. EVA is highly flexible and transparent.

EVA-based non autoclave laminated glass machine is commonly applied in the production of solar panels. The flexibility of EVA allows it to be deformed well based on the shape of the solar cell, which ensures good sealing and protection. The transparency of EVA is important to ensure maximum transmission of sunlight to the solar cell, thereby maximizing the efficiency of the solar panel.

In some ornamental glass applications, EVA laminated glass may be used to form special visual effects. EVA may be combined with glass of different colors or textures to obtain artistic glass products for indoor use. EVA-based non autoclave laminated glass machine is cost-effective in some applications. EVA film is not very costly and processing conditions are not highly restrictive in the use of large-scale production for making solar panels. This makes it a more desirable choice in such cases.

Comparison

In contrast, PVB-based non autoclave laminated glass machines are suitable for general purposes with low requirements for optical transparency and low stress resistance. They offer a best trade-off among performance and cost. SGP-based units are used more in high-security and high-stress applications due to the higher strength of SGP laminated glass, whereas their cost is comparatively higher. EVA-based non autoclave laminated glass machines are suitable for uses where there is flexibility and transparency, such as solar panel manufacturing and glass decoration.

Overall, the choice of non-autoclave PVB/SGP/EVA laminate machine is largely based on the project's requirements. If it's to be employed in automotive, construction, security or solar panel applications, the demands are fully comprehended by having a comprehensive knowledge about the behavior of such laminate machine and films they utilize to achieve the desired output.
