The flame retardant grade of the Kelinai countertop reaches B1 difficult to burn level (in accordance with the national standard GB8624-2012), and its flame retardant performance is excellent. The specific description is as follows:
Combustion performance grade: Verified by the National Quality Supervision and Inspection Center for Fire-Resistant Building Materials, Kelinai is a flame-retardant (B1 grade) material, suitable for residential buildings, public buildings, commercial applications and other scenarios.
Oxygen index: The oxygen index of Corine is approximately 47, which is much higher than the standard of 30 for first-level flame retardancy. The higher the oxygen index is, the better the flame retardant performance of the material is.
Smoke density index: Among the fire resistance performance indicators that must be tested for materials used in public places, the smoke density index SDR of Corine can reach 0.0, which is far lower than the standard of SDR≤75.0 for ordinary artificial stone products.
Fire resistance performance: The fire resistance performance of Corine meets the Class A classification standard for building interior decoration materials stipulated by the National Fire Protection Association of the United States, and also meets the Class 1 Flammability /Flammability standard stipulated by the European Union.
