Definition of SGP glass and PVB glass

Before we begin to compare SGP glass and PVB glass, we first need to understand the definition of the two materials.

SGP glass is a kind of laminated glass with high strength and safety properties. SGP glass is unique in that it uses an SGP intermediate film. This intermediate membrane is an ionic material with excellent strength, toughness and adhesion.

PVB glass, full name of polyvinyl butyrate glass, is a common laminated glass. The main feature of PVB glass is that the intermediate film is made of PVB (polyvinyl butyrate) material, which has good transparency, elasticity and bonding force.

Comparison of SGP glass and PVB glass

Although SGP glass and PVB glass are both laminated glass, there are significant differences in performance and application of the two kinds of glass due to the difference in the material of the intermediate film.

Strength and safety: The strength and safety of SGP glass are better than PVB glass. The strength of SGP intermediate film is 5 times that of PVB intermediate film, and the toughness is 100 times that of PVB intermediate film. This allows the SGP glass to effectively absorb and disperse the impact energy, thereby preventing glass breakage and splashes.

Weather resistance: The weather resistance of SGP glass is also better than that of PVB glass. SGP interfilm can resist the effects of harsh environments such as ultraviolet radiation, high temperature and humidity, while PVB interfilm may appear yellowing and hydrolysis in these environments.

Transparency: In terms of transparency, both SGP glass and PVB glass show good performance. However, due to the high strength and toughness of the SGP intermediate film, SGP glass can be made into thinner interlayers, thus improving transparency.

Application field: Due to the above performance differences, the application field of SGP glass and PVB glass is also different. Because of its high strength and safety, SGP glass is widely used in high-rise buildings, large public places and buildings in storm areas. PVB glass is more commonly used in residential and commercial buildings.

FAQ: Answers to questions about SGP glass and PVB glass

Q: What is the difference between SGP glass and PVB glass?

A: The main difference between SGP glass and PVB glass is the difference in the intermediate membrane material, which leads to the performance differences between the two in terms of strength, safety, weather resistance and transparency.

Q: What are the respective application areas of SGP glass and PVB glass?

A: Because of its high strength and safety, SGP glass is widely used in high-rise buildings, large public places and buildings in storm areas. PVB glass is more commonly used in residential and commercial buildings.

In general, SGP glass and PVB glass are excellent laminated glass materials, but because of their different properties, their applications in construction and engineering projects are also different. When choosing laminated glass, it is necessary to decide which material to use according to the specific needs and conditions of the project.
