A New Era of Door And Window Safety ǀ Flame Retardant Sealing Strips Protect Every Moment

Meirun New Materials is affiliated to Guangdong 3H Hardware Group.Today,let’s learn more about Meirun EPDM frame retardant sealing strip.

Traditional materials often have defects in flame retardant properties. Once they encounter a fire source, they are prone to spread rapidly, posing a great threat to people's lives and property. Therefore, in the current era of increasing attention to safety and environmental protection, finding a safe and reliable flame retardant material has become an urgent market demand.

Meirun EPDM Flame Retardant Sealing Strip

Meirun EPDM flame retardant sealing strip is made of EPDM rubber, flame retardant filler and compounding agent mixed evenly in a certain ratio on a rubber mixer to form a mixed rubber, which is then extruded and vulcanized by an extruder to make it a special sealing strip that is difficult to burn, does not fall off after burning, and can continuously block the spread of smoke and flames. The flame retardant mechanism of the sealing strip is through the synergistic effect of multiple flame retardants. When burning, it can decompose water, absorb a large amount of heat, reduce the temperature of the vulcanized rubber, and prevent the strip from further decomposing; at the same time, the water vapor generated by dehydration can dilute the combustible gas in the flame zone and reduce the combustion rate; and promote the formation of a carbonized layer in the combustion zone of the strip, preventing heat and oxygen from further entering the strip, effectively inhibiting the thermal decomposition of rubber.

The flame retardant performance level of the rubber strip reaches V-0, and the oxygen index is above 30%. It can delay ignition, reduce the speed of flame propagation, and quickly self-extinguish after leaving the fire, effectively enhancing the fireproof sealing performance of the sealing strip; strengthening the building's own fire defense performance; meeting the fire safety performance requirements of building doors and windows; solving the problem of the increasingly rapid development and increasing height of domestic super-high-rise buildings, and excessive reliance on external rescue in the event of a fire, ensuring life safety.
