Professional Rubber Testing Machine , 2.5 Grade Limiting Oxygen Index Tester For Plastics Rubber Foam
Professional Rubber Testing Machine, Limiting Oxygen Index Tester used to determine the minimum oxygen concentration required for polymer combustion. The instrument features simple operation with sensor measurement and digital display results, eliminating manual calculations.
Limiting Oxygen Index Tester meets the manufacturing conditions stipulated by national standard GB2406.
This equipment is essential for testing the burning performance of plastics, rubber, foam, and other materials. It provides accurate results with excellent reproducibility, making it indispensable for flame retardant material research and production.
The Limiting Oxygen Index represents the minimum oxygen concentration (volume percentage) required for material combustion in an oxygen-nitrogen mixed gas stream:
- Oxygen Index < 22: Flammable material
- Oxygen Index 22-27: Combustible material
- Oxygen Index > 27: Flame retardant material
Higher oxygen index values indicate better flame resistance.
