TEC Intumescent Flame Retardant Material
TEC is a two-component solvent-free intumescent flame retardant coating, which is mainly composed of solvent-free epoxy resin, flame retardant, inorganic filler, special functional additives and so on.
Excellent properties
Short drying time ，Low VOC
It is an Eco- friendly coating with solvent-free system, no aromatic solvent volatilization
It can be applied to different substrates (such as aluminum, steel, stainless steel, composite materials, plastics or wood, etc.)
Excellent adhesion on aluminum, steel and other substrates
Excellent mechanical resistance and chemical resistance
Its coating has good insulation property and still remain high insulation performance even the expansion layer generated after fire.
Effectively improve the fire resistance limit of the substrate, It can resist the flame impact of 1300℃ for at least 30 min.
Application
●When applied to the inner walls or casing of the power battery pack, the fireproof coating quickly reacts to high temperatures by forming a resilient protective layer through bubbling. This coating acts as a formidable barrier against heat transfer from the upper cover or side walls to the surrounding environment, enhancing the overall safety of the pack.
● This innovative design aligns with the specifications outlined in GB38031-2020, ensuring compliance with safety standards. In the event of a thermal runaway alarm, occupants within the vehicle are provided with more than 5 minutes to evacuate safely, thanks to the protective properties of the fireproof coating.
Before expansion（L: 2cm*W2cm, thickness: 1mm）
After expansion（thickness: 33mm）
（As shown in the picture）
This is a thermally expanding material that begins to expand when the temperature reaches 200-350°C, expanding more than 30 times, forming a heat-insulating layer that then quickly fills in the gaps, thus preventing the spread of flames.
With the rapid growth of global energy demand, vigorously developing renewable energy is the future trend. Modern renewable energy technology is developing very rapidly. The cost of renewable energy decreases with the mature application of technology. Non-hydroelectric renewable energy such as wind energy, solar energy, geothermal energy, tidal energy and ocean wave energy emerge in endlessly, surpassing the global average annual growth rate of any other energy. How to efficiently store energy is the key to the development of these fields. The high-end foaming materials developed by Xiangyuan New Material can meet the requirements of new energy storage batteries for sealing and sealing materials in the future. These unique materials can effectively play the role of dust prevention, shock prevention, waterproof, flame retardant, aging resistance, and other pollutants during the use of products, reduce maintenance costs and improve energy utilization.
