PVB film in laminated glass
PVB film laminated glass is laminated glass made by sandwiching PVB interlayer film between two or more pieces of glass. The main component of PVB film is polyvinyl butyral, which is the condensation product of polyvinyl alcohol and butyral.
PVB film thickness: 0.38mm~2.28mm
Advantages of PVB film
PVB interlayer can reduce the amount of noise that penetrates the glass, lowering the noise decibel and achieving sound insulation. Laminated glass made with PVB plastic interlayer can effectively block the common noise of occasions of 1000~2000Hz.
Typical Applications:
The composite glass made of PVB/SGP film can absorb the impact energy without producing broken pieces. It is widely used for automotive laminated glass, bullet proof glass, sound proof glass, photovoltaic glass, color glass, etc. In addition to safety performance, it also has excellent anti ultraviolet, sound insulation, light control, heat preservation, heat insulation, shock resistance and other properties. It is an ideal safety glass composite material.
SGP film in laminated glass
SGP film is a new type of polymer material with high molecular and elastic modulus by ionic bonding.SGP film (ionic film) - an ionic mixture of polyethylene terephthalate and metal salts, of which SGP is the abbreviation of DuPont's SentryGlas®Plus film.
Advantages of SGP Diaphragms
High strength and shear modulus, excellent mechanical properties
The shear modulus of SGP is 100 times higher than that of PVB, and the tear strength is 5 times higher than that of PVB.After SGP is laminated, the adhesive layer between the two pieces of glass basically will not produce sliding when the glass is subjected to force, and the two pieces of glass will be like a piece of single piece of glass with equal thickness working as a whole. In this way, the load-bearing capacity is equal to the thickness of the PVB laminated glass load-bearing capacity of 2 times; at the same time, in the case of equal load, equal thickness, SGP laminated glass bending degree of circumference is only 1/4 of the PVB laminated glass.
Superior weather resistance, not easy to age
After the natural outdoor aging test in Florida, USA, accelerated weathering test in Arizona, water boiling and baking test, there is no problem of opening and blistering after 12 years.
Excellent adhesion to metals
SGP and metal have high bond strength, such as aluminium, steel, copper. Laminated glass made of SGP compounded with metal wires, nets and plates can greatly improve the performance of the glass after breakage, with extremely strong resistance to damage and intrusion.
The shear mode of ionic film SGP is more than 50 times than PVB, the tear strength is 5 times than PVB, and the bearing capacity is 2 times than PVB laminated glass. Under the same load and thickness, the bending of SGP laminated glass is only 1/4 of PVB laminated glass. Compared with the laminated glass produced by PVB, the performance of laminated glass produced by SGP film is more superior.
Typical Applications:
Ceiling glass, structural glass building, glass plank road, high-rise exterior wall, glass curtain wall, etc.
PVB/SGP Glass Interlayer Film Extrusion Line
This is the PVB/SGP interlayer film extrusion line from JWELL. The production line is carefully designed and strictly monitored at every step, from precise metering and mixing of raw materials, to extrusion moulding under high temperature and high pressure, to precise cutting, to ensure that every detail reaches the ultimate perfection.PVB and SGP, as high-end architectural glass interlayer materials, are known for their excellent sound insulation, heat insulation, and safety performance. In the production line of JWELL, these materials are given a new life. the softness and adhesion of PVB film, under specific process conditions, perfectly fits the glass to form a strong and transparent safety barrier; while SGP film, with its higher strength and better weather resistance, is the first choice for construction projects pursuing ultimate safety.
