Which is stronger under the same specifications, bulletproof glass or shatterproof glass from a tempered glass factory in Guangzhou?

Bulletproof glass and anti-smash glass each have their strengths in terms of intensity, making it difficult to directly determine which is 'harder' because their design goals and application scenarios are different. Below is a detailed comparison of the two.
- Material composition and structure
Bulletproof glass: Composed of more than two layers of high-strength glass (not tempered glass) combined with a polymer (such as PVB, SGP, etc.) or PC board in the middle. Its structure is usually quite complex, possibly containing multiple layers of glass and film to provide higher bulletproof capability.
Anti-smash glass: Also made using a dry process that combines glass and film under high temperature and pressure, it has good light transmittance. It consists of at least two pieces of glass and one layer of film, with thickness proportional to its function.
II. Function and design goals
Bulletproof glass: The main function is to resist the impact force of projectiles. It can withstand projectiles launched by devices such as the Type 56 and Type 79 rifles by reducing the impact potential energy through its multilayered structure of glass and film, preventing penetration holes from forming.
Anti-smash glass: The main function is to resist smashing and prevent intrusion. It can protect against heavy attacks from tools like hammers, mallets, sticks, axes, etc., by connecting the glass together through the tensile strength and impact resistance of internal films to withstand external assaults.
III. Strength comparison
Bulletproof glass: Although bulletproof glass may shatter upon bullet impact, due to its multilayer structure and adhesive properties of the films, fragments are held together and do not fall off, thus preventing bullets from penetrating. Additionally, bulletproof glass typically has a larger thickness that can reach up to 80mm or more for higher protection capability.
Anti-smash glass: Anti-smash glass primarily resists gravity attacks; its strength is relatively weaker compared to bulletproof glass. However, according to the GA844-2009 standard for anti-smash composite glass, anti-smash glasses are classified into four levels A-D with increasing smash resistance. Level D anti-smash glass must withstand an impact test of up to 362J with continuous strikes up to 30 times or more without creating penetration holes.
IV. Conclusion
Bulletproof glass: Excels in resisting projectile impacts with higher protection levels and thickness.
Anti-smash glass: Has strong capabilities in resisting smashing and preventing intrusion; although its strength is weaker compared to bulletproof glass, it can still meet certain safety needs.
Therefore, it cannot be simply determined which is 'harder' between bulletproof glass and anti-smash glass. They each have unique functions and design goals suitable for different application scenarios. When choosing which type of glass to use, one should make judgments based on specific safety needs and scenarios.
