At our Bell Development, we design sound-absorbing materials tailored to the peak frequencies of sounds we want to absorb through acoustic analysis. Additionally, our sound-absorbing materials can achieve over 33% weight reduction compared to standard products, along with more than 30% improvement in sound absorption performance. Moreover, our sound-absorbing materials excel in thermal insulation, offering performance comparable to glass wool, with a thermal conductivity of 0.037 [W/mK]. They are effective as insulation materials within building partitions and internal walls. Depending on usage conditions, we can add necessary functions to the sound-absorbing materials, such as moldability, flame resistance, heat resistance, and water and oil repellency. 【Features】 ■ We can design sound-absorbing materials that match the frequency of the noise target. ■ We can specify sound insulation performance based on the sound absorption rate of the materials. ■ We can provide functional enhancements to meet the required performance of each specification area. ■ The materials used include polyester fibers and others, considering the environment by avoiding the generation of harmful substances such as SOC and VOC. *For more details, please download the PDF or feel free to contact us.

This document contains knowledge that helps understand the basics of sound-absorbing materials. Sound-absorbing materials are those that absorb sound energy transmitted through the air without reflecting it, converting it into thermal energy, and suppressing reverberation. Reverberation overlaps while noise is present, resulting in loud noise. If you are considering soundproofing measures, we recommend the installation of sound-absorbing materials.

"Tsuru-to" is a high water-retaining mat for high-rise strawberry seedling cultivation. In traditional strawberry cultivation, managing parent plant beds and the occurrence of diseases such as black root rot have been problematic. As a solution, the high-rise seedling cultivation method was devised, but this method faced other issues such as "slow rooting after planting the seedlings" and "poor seedling growth." Therefore, this product was developed as a countermeasure to these problems. [Features] - Good rooting after planting, ensuring the establishment of seedlings - Excellent water retention capability to prevent aging roots - With 2-3 waterings per day, seedlings can grow to the desired root length in about 10 days to 2 weeks - Significant labor savings and simplification of parent plant bed management - High effectiveness expected in preventing the occurrence of diseases such as black root rot *For more details, please refer to the related links or feel free to contact us.

"Aqua Veil" is a bottom watering mat made of polyester fibers that have been treated for hydrophilicity, providing excellent water diffusion and absorption properties. The combination of the "liquid reservoir" corresponding to the thickness of the mat and the "root barrier sheet" achieves uniform irrigation effects, and by allowing excess moisture to drain externally, it prevents root rot. Since a breathable root barrier sheet is pre-attached, roots do not enter the interior, allowing for repeated use. 【Features】 ■ Water diffusion, absorption, and root barrier properties ■ Suitable for seedling cultivation ■ Prevents root rot by draining excess moisture ■ Can be cut to specified dimensions (such as sizes for rice seedling boxes) ■ Can be produced in black color for the outer surface *For more details, please feel free to contact us. *Inquiries can be made at "03-6455-0702".
