Welcome to our latest edition focusing on the revolutionary advancements in glass tempering technology. This field has seen significant strides in both thermal and chemical tempering methods, each bringing unique benefits to the table. Tempering solutions by Pujol Group are empowering their partners to better quality through innovative solutions.
Thermal Tempering: The Heat is On w/ Temper-Flex

Thermal tempering involves heating glass to a high temperature and then rapidly cooling it. This process enhances the strength of the glass by at least four to five times compared to annealed glass. It’s not just about strength; thermally tempered glass is also safer. In the event of breakage, it shatters into small, dull-edged pieces, significantly reducing injury risks. The Pujol Temper-Flex solution is one of the most efficient products in the market renowned for its flatness on 1/8″ glass. It is the perfect compliment to their range of glass laminating solutions allowing their partners full control of their tempered & and laminated glass products.
Advantages of Thermal Tempering:
- Increased Strength: Resists physical impact and extreme weather conditions.
- Enhanced Safety: Breaks into less harmful pieces, ensuring user safety.
- Thermal Resistance: Tolerates sudden temperature changes, ideal for various climates.
- Temper-Flex Flatness: The flatter the glass, the lower the optical distortion of the final product. Flatter glass also compliments a secondary lamination process allowing to use less interlayer to fill roller wave.
Chemical Tempering: The Invisible Shield

Chemical tempering, on the other hand, involves a bath of molten salt at lower temperatures. This process exchanges smaller ions in the glass with larger ones from the salt, creating a layer of compression on the glass surface. The result is a piece of glass with enhanced strength and flexibility, making it resistant to more severe impacts.

Advantages of Chemical Tempering:
- Superior Strength: Ideal solution for thinner glass requiring high impact resistance.
- Flexibility: Maintains clarity and light transmission properties. Thin chemically tempered glass will bend like polymers without breaking.
- Durability:Resistant to scratches and environmental wear and tear. It can even be cut like annealed glass without shattering into thousands of pieces reducing waste for unforeseen processing errors.
- No optical distortion: As the glass is not heated to the temperatures required for thermal tempering there is nearly no optical distortion to the final product because there is no roller wave.
Applications Galore:
Both tempering techniques have broad applications, from smartphone screens, and architectural facades to automotive windshields and various household items. The future of glass continues to get thinner, incorporate more electronic components, all while requiring higher strength with a thinner overall product. These methods have revolutionized the way we use glass, making it a versatile, durable, and safer material in our daily lives.
