Flame-retardant sealing strips can also be called fire-proof sealing strips, fire-resistant expansion sealing strips, smoke-proof 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, which can be divided 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.

In addition to good fire-resistant expansion performance, flame-retardant sealing strip products also have good flexibility, which makes them have excellent sealing and shockproof performance. 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, which provides convenience for users.

Flame-retardant sealing strip products are ideal fire-proof sealing materials for building fire-proof components. It is mainly used for the fire-proof sealing of various steel fire-proof doors, such as the side seam and middle seam sealing of double-leaf doors. At the same time, it can be widely used in the fields of waterproof, fireproof, sealing, fireproof glass lines and safes of elevator mezzanine doors.
