Chemical/thermal strengthening

Chemically strengthened glass offers an improved scratching, impact and bending strength, as well as an increased temperature stability.

• weight reduction, but stable,
• decreased mounting costs.

The glasses can be flexibly handled, bent, polished matte-finished or etched.

	Chemically strengthened glass	Untreated glass
Impact resistance	4 - 10 Joule (depending on conditions of test)	1 - 2 Joule (1 Joule = 1 N*m)
Flexibility strength σ bB: (acc. EN 12337)	150 N/mm²	50 N/mm²
Resistance to temperature (acc. to DIN 52313)	350°C for 1 mm glass 300°C for 2 mm glass 270°C for 3 mm glass 250°C for 4 mm glass	170°C for 1 mm glass 130°C for 2 mm glass 120°C for 3 mm glass 100°C for 4 mm glass
Vicker hardness	626 HV 0,2/15	550 HV 0,2/15
Max. application temperature	300°C *	450°C

(*above 300° C the chemical hardening can be reduced or lost)

The above-mentioned data are approximate values. All remaining physical and chemical characteristics of the glass remain to a large extent uninfluenced.

Beside the chemical strengthening we also offer thermal tempered glass as safety glass with the following characteristics:

• high impact strength
• high bending strength
• high scratch resistance
• enhanced resistance to temperature changes
• breaks into small particles
