Audited Supplier Flame-retardant sealing strips can also be called fire-resistant sealing strips, fire-resistant expansion sealing strips, smoke-proof and flame-retardant sealing strips or high-temperature resistant rubber strips. The following will introduce the main characteristics and material classification of flame-retardant sealing strips; the materials of flame-retardant sealing strips can be classified into natural rubber flame-retardant sealing strips, EPDM flame-retardant sealing strips, PVC (plastic) flame-retardant sealing strips and silicone flame-retardant sealing strips. sealing strip.
Fire retardant sealing strips are mainly used for fire door products between doors and between doors. When a room is on fire and the temperature reaches a certain value, it can isolate the air circulation between the two rooms and prevent the flame from spreading. The application of this product has replaced the domestic asbestos rope that was previously used in fire door gaps, and has passed the test of the National Fixed Fire Extinguishing System and Fire-Resistant Components Quality Supervision and Inspection Center, and all indicators are qualified.
In addition to good fire expansion resistance, flame retardant sealing strip products also have good flexibility, giving them excellent sealing and shock-proof properties. At the same time, due to the extrusion process, flexible fire-resistant expansion sealing strips of various shapes and lengths can be produced according to user requirements, providing convenience for users.
Flame retardant sealing strip products are ideal fireproof sealing materials for building fireproof components. It is mainly used for fire sealing of various steel fire doors, such as side seam and center seam sealing of double doors. At the same time, it can be widely used in the fields of waterproofing, fireproofing, sealing, fireproof glass lines and safes for elevator mezzanine doors.
Product characteristics of flame-retardant sealing strips: expansion temperature: initial expansion temperature 199°C, main body expansion temperature 347°C; linear expansion multiple: greater than or equal to 3 times the thickness of the original expansion body; high temperature combustion resistance: the temperature rises to 980°C and remains 30min, no burning, no ashing; smoke resistance performance: the fire resistance test was carried out for 72 minutes, there was no obvious smoke leakage on the left and right sides of the door installation sealing strips, and there was no obvious smoke leakage in the left and right gaps, the smoke prevention performance was greater than 72min; environmental resistance: at room temperature, 90 Under humidity conditions, the expansion ratio remains unchanged for 120 days.
