Product Description: TONMAX THG‑2000 Series intumescent fire‑stop separator adopts special intumescent flame‑retardant technology. It expands 20‑50 times quickly under high‑temperature or open‑flame to form dense char layer, isolates heat and oxygen to retard fire spread. Resists temperature above 1000℃, asbestos‑free & halogen‑free, RoHS compliant. Flexible, cuttable and bendable for building, cable tray, ventilation duct and steel‑structure fire‑protection. Store dry below 50℃, avoid pressure loading.

Intumescent Fire‑Stop Separator THG‑2000 Series
Product Overview
TONMAX THG‑2000 Series intumescent fire‑stop separator is high‑performance fire‑proof material manufactured with special intumescent flame‑retardant technology. When exposed to high‑temperature or open‑flame conditions, the separator expands rapidly and forms a dense carbonized char layer. This char layer effectively isolates heat and oxygen, restrains fire propagation, and delivers reliable fire‑protection for building structures, cables, pipelines and other facilities.
Main Applications
• Fire‑safety barrier protection for building structural gaps and penetrations
• Fire‑stop shielding for cables and cable‑tray assemblies
• Fire‑protection isolation for ventilation pipelines and duct systems
• Flexible fire‑proof liner for steel‑structure components
• Passive fire‑protection partition for industrial equipment compartments
Core Advantages
✅ High‑efficiency flame retardancy: expands 20‑50 times original volume upon fire exposure to build thermal‑insulating fire barrier
✅ Excellent high‑temperature resistance: withstand temperature over 1000 ℃ to protect substrates from direct flame erosion
✅ Light‑weight & eco‑friendly: asbestos‑free, halogen‑free, complies with RoHS and fire‑protection environmental standards
✅ Easy installation: flexible sheet format, can be cut and bent, fits complex surfaces such as steel‑structure, cable trays and ventilation ducts
Storage Note: Store indoors under dry condition below 50℃; avoid pressure loads on the material.
