PROMASEAL® FyreStrip 德国 Promat 保全 膨胀型防火密封条
PROMASEAL® FyreStrip is a highly compressible, flexible, fire resistant expansion strip seal which is used where movement joints are formed in the structure of a building. It consists of layers of PROMASEAL® Grafitex intumescent material bonded to a special foam and it has been successfully tested for up to 240 minute fire resistance for movement joint seals within concrete/masonry compartment floors and walls (with an equal or greater fire resistance level).
PROMASEAL® FyreStrip is ideal for sealing high movement joints at junctions between compartment walls and floors. Its flexibility makes them suitable for use in a variety of configurations. The fire performance of PROMASEAL® FyreStrip will vary according to the particular application. The width of the gap into which the strip will be inserted as well as the orientation of the strip affect the level of fire resistance provided.
The thickness of PROMASEAL® FyreStrip is determined by the minimum and maximum width of the gap expected during the lifetime of the building.
一、产品基本信息
- 产品名称：PROMASEAL® FyreStrip
- 产品类型：防火膨胀密封条
- 核心特性：高度可压缩、柔韧性强，专为建筑结构中的活动接缝设计，兼具密封与防火功能。
二、核心功能与原理
作为防火膨胀密封条，其核心作用是在建筑结构的活动接缝处形成可靠密封。在火灾等紧急情况下，密封条可通过膨胀作用封闭缝隙，阻止火焰、热气及烟雾蔓延，从而维持建筑防火分区的完整性。
三、应用领域
主要用于建筑结构中存在伸缩缝、活动接缝的场景，包括但不限于：
- 墙体与墙体之间的活动接缝
- 楼板与墙体的连接缝
- 吊顶与结构框架的伸缩缝等
适用于需要应对接缝位移的建筑部位，如大型公共建筑、高层建筑等。
四、性能优点
- 高位移适应性：可处理高达 50% 的接缝移动，能适应建筑因温度变化、沉降等产生的接缝伸缩或位移，保持密封效果稳定。
- 宽缝隙覆盖：可适配最大 100mm 的缝隙，满足不同建筑接缝尺寸的密封需求。
- 安装灵活性：支持垂直或水平方向安装，适配多种建筑构造场景，简化施工流程。
以上产品信息，聚焦其核心功能、应用场景及性能优势，为建筑防火密封解决方案提供关键参考。
