Climbing Gear Storage Bag
Climbing gear storage bags are equipment used in outdoor adventures to encapsulate and protect important items (such as clothing, electronic devices, first-aid supplies, food, etc.). In extreme environments, they face two major risks:
Fire Hazard: Open flames (stoves, bonfires) at campsites, lightning, or equipment short circuits may ignite the storage bag;
Environmental Challenges: Low temperatures at high altitudes (-30℃ and below), rock friction, ice and snow abrasion, etc., can easily cause material embrittlement or damage.
Ordinary flame-retardant fabrics (such as coated fabrics) easily harden and crack at low temperatures, and repeated friction will damage the flame-retardant layer, losing its protective function.
Polyimide Climbing Gear Storage Bag
Polyimide non-woven fabric can be used to manufacture emergency fire blankets, fire suits for arc protection, armored protective clothing, fire-resistant racing suits, and heat insulation materials for high-temperature equipment, etc.
Inherently Flame Retardant
The polyimide molecular structure contains aromatic heterocycles. When exposed to fire, it carbonizes to form a dense heat-insulating layer, does not melt or drip, does not self-ignite, and self-extinguishes within 2 seconds of removing the flame.
High-Temperature Resistance: Long-term resistance to temperatures of 260℃~300℃, short-term resistance to flame impact (such as splashing sparks) above 500℃.
Low-Temperature Resistance
Low-Temperature Toughness: Remains flexible at -196℃ (liquid nitrogen temperature), with no risk of embrittlement or cracking, suitable for extreme environments such as snow mountains and polar regions.
Resistance to Cold and Heat Cycles: The material has a low coefficient of thermal expansion, and its performance remains stable after repeatedly experiencing drastic temperature changes (such as high temperatures during the day and low temperatures at night).
Friction Resistance and Durability
Surface Strength: The tensile strength of polyimide fibers is ≥500MPa, higher than that of most engineering plastics, and is not easily damaged when rubbed against rocks or ice.
Abrasion Test: Passes abrasion tests, with no pilling or holes on the surface, and the flame-retardant layer remains intact.
Applications of Polyimide Flame-Retardant Fabric
Structural Design:
Double-Layer Composite: Outer layer of polyimide flame-retardant fabric for friction resistance, inner layer of aluminum foil or aerogel for enhanced heat insulation;
Lightweight: 60% lighter than traditional metal fireproof boxes, easy to carry.
Usage Scenarios:
Protect electronic devices (such as GPS, satellite phones) from being ignited by flying sparks from bonfires;
Store flammable items (fuel tanks, spare batteries) to prevent friction from causing fires during transportation;
In emergencies, it can be used as a temporary fire blanket to cover the fire source or wrap the body.
