In the field of optical fiber communications, the performance of the coating directly affects the signal transmission efficiency and equipment durability. As the core material of optical fiber coating, low refractive index monomer is the key to improving optical fiber performance by optimizing optical properties and mechanical strength. The LM-301 low refractive index monomer launched by Shenzhen U-Sunny is gradually becoming an industry benchmark with its excellent refractive index control and stability.
The core role of low refractive index monomers
Low refractive index monomers achieve precise control of refractive index through highly fluorinated structures. For example, the refractive index (n20/D) of hexafluoroisopropyl acrylate is only 1.38, while the refractive index of 1H,1H,2H,2H-heptadecafluorodecyl methacrylate (HDFDMA) is even lower, at 1.35. This type of material not only reduces optical signal loss, but also has hydrophobicity and low surface energy, and can withstand harsh environments such as humidity and high temperature.
Technological breakthrough of LM-301
Shenzhen Youyang's LM-301 is specially designed for optical fiber coating. Its refractive index is controlled in the range of 1.36-1.39. Compared with similar products, it has both low viscosity and fast curing characteristics. By introducing polyether urethane acrylate oligomers, LM-301 forms a coating with high transmittance (≥92%) and strong adhesion (>3.5 MPa) after UV curing, which significantly improves the bending resistance of optical fiber. In addition, its temperature resistance range is -60℃ to 220℃, which is suitable for extreme scenarios such as submarine optical cables and 5G base stations.
Industry application scenarios
5G communication: LM-301's low signal loss characteristics can reduce energy attenuation in high-frequency transmission and improve base station coverage efficiency.
Data center: Its fast curing process (10-30 seconds) adapts to the needs of high-speed optical fiber production and reduces manufacturing costs.
Industrial sensing: Chemical corrosion resistance and high mechanical strength ensure the long-term stability of optical fiber in oily and high-temperature environments.
