What is the interlayer of laminated glass?



Laminated glass, also known as laminated glass is two or more pieces of glass, sandwiched between one or more layers of organic polymer interlayer, after a special high-temperature preload (or vacuum) and high temperature and high pressure process, so that Glass and the middle film as one of the permanent bonding of the composite glass products. Its features are transparent, explosion-proof, waterproof, anti-ultraviolet. Widely used in engineering decoration, outdoor decoration, home decoration and so on.


Common laminated glass interlayer: PVB, SGP, EVA, PU and so on.

In addition, there are some more special, such as color interlayer film laminated glass, SGX class printing interlayer film laminated glass, XIR class LOW-E interlayer film laminated glass. Inlaid decorative pieces (metal mesh, metal plates, etc.) Folder plastic glass, embedded PET material folder plastic glass decorative and functional glass folder.


The main types:

According to the different melting point of the middle film can be divided into: low temperature laminated glass, high temperature laminated glass, insulated glass.

According to the different materials in the middle folder can be divided into: clip paper, clip cloth, clip plants, clip wire, clip fabric,clip metal wire, and many other types;

According to the interlayer between the different bonding methods can be divided into: mixing method of laminated glass, dry laminated glass, insulated plastic laminated glass;

According to the different types of laminated plastic can be divided into: general laminated glass and bullet-proof glass.


Material properties:

Even if the glass fragments, debris will be stuck on the film, broken glass surface remains clean and smooth. This effectively prevents the debris from piercing and penetrating the fall event, to ensure personal safety.

In the relatively more developed countries, most of the architectural glass are laminated glass, not only to avoid injury, but also because the laminated glass has excellent seismic capacity. The middle membrane can resist the continuous attack of the weapon such as the hammer, the chopping knife and so on, but also can resist the bullets penetrating in quite long time, its security guarding degree is extremely high.

The glass breaks safely and may break down under heavy ball impact, but the monolithic glass remains intact, and fragments and sharp small pieces are still sticking to the interlayer. When the glass breaks, the debris does not disperse.

Toughened glass need bigger impact force just broken, once broken, the whole piece of glass burst into numerous sleek glass particles, but will fall down.

Annealed glass breaks at a bump, typical broken condition, into many rectangular sharp fragments.

Wired glass broken, tooth fragments surrounded by the mouth of the cave, and around the penetration points have more shards of glass, metal wire fracture length.
