Heat-insulating and fireproof materials

TONMAX Nano Insulation Board TBF-2000 Series is a new-generation silica-based thermal barrier material designed for EV battery packs. It slows thermal runaway propagation and improves cell performance at low temperature. With stable low thermal conductivity up to 1200℃, better thermal runaway resistance than aerogel, compatible with prismatic, pouch and energy storage batteries.

TONMAX Fiberglass Aerogel VT‑6670H is flexible thermal insulation paper composited with nano‑silica aerogel and inorganic fiber. 3‑5 times better insulation than traditional materials, waterproof, fire‑retardant for battery thermal protection.

TONMAX Ceramic Fiber Aerogel VT‑6660BF is high‑performance ceramic fiber paper for power lithium‑ion batteries. Good thermal insulation & cushioning, easy for die‑cutting, prevents cell thermal runaway and improves EV safety.

TONMAX Pre‑Oxidized Fiber Aerogel Felt VT‑6630N is nano‑aerogel composite felt with organic pre‑oxidized fiber. Ultra‑low thermal conductivity, fire‑proof & waterproof, for battery thermal insulation, buffering and protection.

TONMAX THG‑2000 Series intumescent fire‑stop separator is high‑performance fire‑proof material with special intumescent flame‑retardant technology. It rapidly expands under high‑temperature or open‑flame condition to form dense char layer, blocking heat & oxygen and slowing flame spread for building, cable and pipeline fire‑safety protection.

TONMAX Vacuum Insulation Panel TBF‑2000‑003A consists of core material, barrier film and getter. It achieves superior thermal insulation by high vacuum structure. Initial thermal conductivity ≤3.5mW/(m·k), thermal resistance 8-10 times of traditional insulation materials, suitable for lithium battery packs, refrigerators, freezers and construction insulation.
