High-strength, heat-resistant and corrosion-resistant industrial glass parts including sight glass, observation window glass, tempered structural glass, pressure-resistant glass and custom industrial blanks for mechanical, chemical, vacuum and instrumentation process systems.
This page provides a structured overview of industrial glass substrates, core component types, surface treatments, manufacturing capacity and typical industrial use cases. All parameters shown are typical for reference; final specifications depend on material grade, processing method and customer engineering requirements.
Felix Glass supports high-hardness, corrosion-resistant, high-temperature optical and structural glass components for industrial instrumentation, vacuum equipment, chemical engineering, power energy and mechanical protection systems.
Values are typical reference data. Actual performance depends on thickness, tempering state and processing conditions. Industrial glass selection must match mechanical load, temperature range, chemical environment and assembly requirements instead of single performance indicators.
| Material Type | Typical Range | Core Industrial Properties | Typical Tolerance | Industrial Use |
|---|---|---|---|---|
| Soda Lime Industrial Glass | 2mm-12mm | Good flatness, general mechanical strength, cost efficient | +/-0.1mm | General industrial observation covers, conventional protective windows |
| Tempered Soda Lime Glass | 3mm-15mm | Improved impact resistance, uniform stress distribution | +/-0.1mm | Equipment protective covers, ordinary pressure sight windows |
| Borosilicate Industrial Glass | 1.5mm-10mm | Low expansion, thermal shock resistance, chemical stability | +/-0.05mm | High-temperature equipment, chemical vessels, laboratory fixtures |
| Aluminosilicate Industrial Glass | 2mm-8mm | High hardness, bending strength, scratch resistance | +/-0.05mm | Mechanical structural parts, wear-resistant observation windows |
| Fused Silica Industrial Glass | 1mm-6mm | Excellent thermal stability and low thermal expansion | +/-0.03mm | Ultra-high temp equipment, UV industrial systems, precision instruments |
Typical sizes and performance ranges are for reference only. Final design should be confirmed by drawings, load conditions, temperature range and sealing structure.

Borosilicate glass provides better thermal shock resistance and chemical stability, while tempered soda lime glass is cost efficient for general protection and ordinary pressure observation windows.
Borosilicate glass is suitable for many high-temperature observation applications. Fused silica is preferred when ultra-high temperature stability and very low thermal expansion are required.
High-purity borosilicate industrial glass is commonly selected for acid-base, chemical workshop and biochemical instrumentation environments because of its chemical stability.
Yes. Round, square, rectangular and custom contour glass can be manufactured with CNC cutting, drilling, slotting, polished edges and mounting holes based on drawings.
Typical tolerance ranges are about +/-0.1mm to +/-0.03mm depending on material, thickness, processing method and inspection requirements.
Drawings, 3D files when available, thickness, material preference, application environment, temperature, pressure, chemical exposure and assembly requirements help engineering evaluation.
