適用塑膠管外徑範圍 (Pipe diameter - range):20 - 51 mm(適用於 1.5 英吋及以下的管路)
阻火圈外徑 (Collar outside diameter):67 mm
外殼材質:A2 S.S (Stainless Steel) 不銹鋼不生鏽材質,具備優異的耐腐蝕性。
核心特性:符合 BS 和 UL 阻火標準。當環境溫度達到約 250 °C 時,內部防火膨脹材料會迅速膨脹(膨脹率高達 1:17),將被燒毀軟化的塑料管道完全擠壓封死,從而在牆體或樓板處形成堅固的防火與防煙屏障

Core Features: Fully compliant with BS and UL firestop standards. When the ambient temperature reaches approximately 250 °C, the internal intumescent material expands rapidly (with an expansion ratio up to 1:17). This completely crushes and seals the softening plastic pipe destroyed by the fire, creating a solid fire and smoke barrier at walls or floor penetrations.
