1. Key Benefits of Kapok Fiber
Superior Thermal Insulation
Kapok fiber provides outstanding thermal insulation due to its hollow structure that traps air and minimizes heat transfer.
- Thermal Conductivity: 0.035–0.040 W/m·K
- Comparison: Better than cotton (0.043–0.050) and similar to polyester.
This makes kapok perfect for eco-friendly wall insulation, jackets, sleeping bags, and home products such as mattresses and pillows.

Excellent Sound Absorption Acoustic Properties (Sound Absorption)
Kapok fiber offers exceptional acoustic performance, achieving a Sound Absorption Coefficient (SAC) of up to 0.70 at mid to high frequencies. As a result, it is highly effective for noise control and is widely used in acoustic panels for studios and offices, noise-reduction components in automotive interiors, and soundproofing solutions for sustainable buildings. These properties make kapok a practical choice for industries seeking efficient sound absorption materials.
Truly Eco-Friendly
In addition to its acoustic benefits, kapok is truly eco-friendly. Unlike polyester, it is 100% biodegradable, requires minimal chemical processing, and produces low carbon emissions. Therefore, choosing kapok fiber not only supports the use of renewable resources but also helps reduce plastic waste. This combination of sustainability and high performance makes kapok an ideal solution for both environmental responsibility and superior material functionality.
