The Interlayer Type of Laminated Glass
As compared to normal glass, laminated glass is a robust safety glass that is hard to break. Even if does break, it stays intact and does not shatter into a million shards.
The Interlayers are used to permanently bond two plies of glass in a laminated configuration. Laminated glass is a great choice for many applications to meet a variety of requirements including acoustic, aesthetic, blast-mitigating, hurricane, safety and ultraviolet protection.
1. Common Interlayer Options
SYP offers a vast selection of interlayer options to meet your specific requirements.
I. Polyvinyl butyral (PVB) Interlayer
For standard glazing applications, PVB is the most common interlayer type, and is widely used through the North America and the rest of the world. SYP provides several PVB Interlayer Types, such as Tinted PVB Interlayer and Acoustic PVB Interlayer etc. The standard PVB Thinkess is:
II. SentryGlas? (SGP) Interlayer
SGP interlayer (Sentry glass plus) SGP interlayer material is an ion polymer ofethylene and methyl acid ester,it offers high safety requirement in some areas. An ionoplast interlayer bonded directly between two layers of glass for superior protection. The rigid interlayer minimizes deflection. The standard SGP Thinkess is:
III. Ethylene Vinyl Acetate (EVA) Interlayer
EVA ‘s cost performance is higher. Compared with PVB and SGP, EVA has better fluidity, lower melting temperature and can be processed at temperatures up to 110 °C.
EVA has a good fluidity of the film layer, and can be subjected to a process such as wire drawing and engraving in the film layer to produce a beautiful decorative glass with a pattern and a pattern. EVA has good water resistance, but its UV resistance is weak. It is easy to yellow and black in long-term sun exposure, so it is mainly used for indoor partitions.
2. PVB vs SGP
领英推荐
While PVB is the oldest inter layer used to laminate glass, (It’s first time use dates to 1930’s) there are other polymers competing with it. Another popular interlayer material is SentryGlas Plus (SGP).
SGP is an excellent material to be used for laminating glass in outdoor use. Although Laminated glass that uses SGP as an interlayer has higher cost, however it is cost -effective because of its advantages. For example; SGP Laminated glass has great clarity.
SGP interlayer is 5 times stronger than PVB. It is reportedly 100 times more rigid than??PVB. SGP is ideal for use in laminated glass for outdoor projects. Unlike PVB, it has high endurance for tough weather conditions. The exposed corners of PVB tend to absorb water, so it starts decaying within a year or two.?SGP laminated glass isn’t posed to such concern.
Even if glass panes on both sides of an SGP Laminated glass get damaged, it can stay intact. This property makes it?ideal for security purposes.
