In modern architecture and industrial design, laminated safety glass has become the preferred material due to its superior impact resistance, sound insulation, and decorative properties. Its core advantages stem from a variety of specialized auxiliary materials used in the production process, which collectively determine the glass's performance and applicable scenarios. The following details the main auxiliary materials and their functions.
The core of laminated glass lies in its intermediate layer material, which directly affects the product's safety and durability.
PVB Film: As the most commonly used intermediate layer, PVB film is renowned for its high transparency and impact resistance. It effectively absorbs impact energy, preventing shattering glass fragments, and is widely used in building curtain walls, automotive windshields, and bulletproof glass.
Accessories for PVB film lamination:
1. Vacuum bag film, which can be used for both flat glass lamination and bend glass lamination.

2. Bag sealing tape or sealing machines, Vacuum valve, silicone pipe.
SGP Film: A representative of ionomer interlayer films, SGP film has significantly higher strength than PVB, making it particularly suitable for scenarios with high load-bearing requirements, such as aquariums, walkways, and large public facilities. It can withstand greater loads without easily deforming.
Accessories for SGP film lamination:
1. Vacuum bag film, Bag sealing tape or machines, Vacuum valve, silicone pipe, which are the same as PVB film lamination.
2. Seal stripes for edge sealing.
EVA film: It is relatively inexpensive and easy to process. EVA film is mostly used in ordinary laminated glass, such as home decorative glass lamination, Glass doors and windows, to provide basic safety protection and sound insulation.
Accessories for EVA film lamination:
1. Silicone Vacuum bag film and Teflon mesh, which can recycle used
