Borosilicate 4.0 glass (fire resistant glass)

Low expansion coefficient, high softening temperature, light weight, high mechanical strength, good fire resistance. Is a single piece of fireproof glass selection material, can also be coated, hollow and other methods made of better comprehensive efficiency of building energy-saving fireproof materials.

Excellent fire resistance

High softening point, stable for fire performance to provide fundamental protection, fire time more than 120 minutes. With high transparency, while maintaining the transparency and beauty of the building, it can still ensure people's vision in case of fire for escape and rescue.

Super high chemical stability

Acid resistance H2 (1.1mg /dm2 6h)

Alkali resistance Grade A2 (86 mg /dm2 3h)

Good fire resistance, stable and not afraid of UV rays

High strength and ultra-light performance

Lighter than ordinary glass more than 8%, at the same time has super high mechanical strength, strong and light characteristics significantly reduce the building weight.

Excellent optical properties

Low iron, environmental protection formula, high transmittance, visible light transmittance of 92%, excellent optical quality to provide distortion-free visual effects.

The original size can be up to 4500 mm ×2440 mm, the thickness of 4 mm to 15 mm, the middle size can be produced according to customer demand.

No danger of self-detonation

Self-explosion is one of the most difficult hidden dangers to overcome in building safety glass at present. High borosilicate fire-proof glass has no nickel in raw materials and system, and no NiS crystal in all finished glass products, thus eliminating the hidden danger of self-explosion.

machinability

High borosilicate glass can be cut, edging, punching, coating and other processing before toughening. High borosilicate glass can be used with other glass to make the building energy-saving fireproof materials with better comprehensive efficiency by the methods of laminating, hollow, vacuum, etc.

Double security guarantee

All tempered monolithic high borosilicate fireproof glass can meet the requirements of fire resistance and safety performance.

Application: Used in glass curtain wall, fireproof window, smoke hanging wall, fireproof partition, fireproof glass door, partition wall without insulation requirement
