Pvc Fireproof Expansion Strip

Product Introduction

This series of PVC fireproof expansion strips is a specialized fireproof sealing accessory made by refining PVC substrate with flame-retardant expansion formula. When exposed to high temperature flames, it can automatically and quickly expand and seal gaps, effectively blocking the spread of smoke and fire, and providing multiple functions such as sealing, fire prevention, smoke isolation, and sound insulation. It is suitable for various building fire protection applications such as fire doors, anti-theft doors, fire doors and windows, cabinet walls, etc. It is an essential material for building fire protection and sealing.

Product Features

Automatically expands in the event of fire, tightly seals, and instantly expands and foams in the event of high temperatures or open flames, doubling the volume and quickly filling the gaps between door frames, door leaves, and walls, effectively blocking the flow of flames, thick smoke, and hot air, and preventing the spread of fire.

The fire-resistant, flame-retardant and smoke isolating effect is good. It adopts a high flame-retardant PVC formula, which is not easy to burn and self extinguishes after leaving the fire. It has good temperature resistance and does not deform or age under normal temperature conditions. It can effectively block smoke penetration and improve fire and security levels.

Good toughness and high adhesion. The product has a flexible texture, easy cutting, and can adapt to various irregular gaps in door and frame seams. It fits tightly and has the wind, dust, sound insulation, and thermal insulation functions of ordinary sealing strips at room temperature.

Made of weather resistant, durable, and anti-aging high-quality PVC raw materials, it is resistant to ultraviolet rays, high and low temperatures, and aging. It does not crack, shrink, or harden after long-term use, and can be used stably in both indoor and outdoor environments, with a long service life.

Easy installation, strong universality, complete specifications, can be cut freely, can be embedded with card slots, can be glued back, easy construction, no need for complex tools, suitable for the vast majority of standard fire doors, anti-theft doors, fire escape doors and windows.
