Fire-retardant cotton is used in the battery pack of electric bicycles to protect the safety of riders.

Electric bicycle battery fires are increasingly frequent.

90% of electric bicycle fires are caused by battery thermal runaway.

What are the dangers of an electric bicycle battery explosion?

① High-temperature impact: The temperature of a runaway battery cell exceeds 800℃ in 3 seconds, and it only takes 45 seconds to ignite the entire vehicle. In parking areas, it may ignite nearby vehicles, causing spreading fires and chain reactions, affecting economic property and personal safety.

② Deadly smoke: Burning releases hydrogen cyanide gas; inhaling two breaths can cause incapacitation.

③ Escape difficulties: In residential buildings, the fire spreads at a rate of 1 floor per minute, far exceeding the human escape limit.

Pre-oxidized silk fireproof cotton

Kaidun Industry produces and sells pre-oxidized silk fireproof cotton in various specifications and sizes, supporting flexible customization of weight (80-2000g/m²), width (1-2.4m), and thickness (1-15mm) to meet diverse needs.

① Flame retardant and fireproof

Pre-oxidized silk fireproof cotton has a long-term temperature resistance of 200-300℃ and an instantaneous temperature resistance of 1000℃.

It has flame-retardant, fireproof, and high-temperature resistant properties, with a limiting oxygen index >45%, making it difficult to burn. When exposed to open flames, the fireproof cotton directly carbonizes without burning, spreading fire, or dripping. The thermal conductivity is as low as 0.035, providing heat resistance and insulation.

② Corrosion resistance

Resistant to chemical corrosion, acids, and alkalis, and anti-aging.

③ Good spinnability

Easy to cut, fold, and has good spinnability.

The felt is soft, skin-friendly, and not scratchy. It is resistant to folding and can be wrapped in any shape.

④ Insulation

Pre-oxidized silk fireproof cotton has electrical insulation properties and a low carbon content.

⑤ Eco-friendly material

Pre-oxidized silk fireproof cotton is an eco-friendly and biodegradable material.

Water repellency reaches 98%.

Pre-oxidized silk fireproof cotton battery wrapping

Wrapping batteries with pre-oxidized silk fireproof cotton can reduce battery replacement costs, lower battery maintenance costs, and reduce the risk of thermal expansion leading to explosions.
