With the continuous expansion of LED technology in lighting, display, and other optical devices, the requirements for optical packaging materials are becoming increasingly high, especially in the manufacturing of high-performance LED light sources and optical modules. The stability, transparency, high temperature resistance, and anti-interference ability of materials have become key standards for measuring material quality. In this regard, Yilian’s SIPA 1840 is a high-purity two-component thermosetting organic silicon material, which perfectly solves these technical problems and has become an indispensable choice for many enterprises in the LED optical encapsulation process. Background: The demand and challenges of optical packagingThe application of optical devices in LED lighting fixtures is becoming increasingly widespread, not only dominating the traditional lighting field, but also playing an important role in multiple fields such as high-definition display, automotive lighting, and industrial applications. These LED optical modules typically require high transparency, excellent thermal stability, resistance to UV aging, and excellent resistance to mechanical shock and vibration. In addition, they also need to have strong resistance to moisture erosion and pollution.However, in various complex application environments, these requirements undoubtedly increase the challenges in the design and manufacturing process. For example, LED modules need to work stably in high temperature and humid environments, and avoid light decay caused by material aging to ensure that they maintain good optical properties during long-term use.Traditional optical packaging materials often have disadvantages such as insufficient transparency, susceptibility to yellowing, poor high-temperature resistance, and precision control is also a major challenge in the manufacturing process. Especially in the production process, if the curing is uneven or the curing time is too long, it may cause bubbles, textures, or uneven surfaces in the packaging layer, affecting the light efficiency and aesthetics of the LED light source. Therefore, when choosing packaging materials, how to ensure that the…

Elaplus Submarine Cable Sealing Solution – Recommended PUR 1661

2025-01-08

With the continuous expansion of deep-sea operations, the sealing and protection of submarine cables have gradually become a focus of attention in the industry. Submarine cables are subjected to extreme environmental conditions, including high water pressure, corrosive saltwater, extremely low temperatures, and prolonged usage loads. Therefore, the sealing material of submarine cables not only needs to have excellent waterproof and moisture-proof performance, but also needs to maintain sufficient hardness and stability in extremely deep waters (such as 100 meters deep). Customer needs and challengesThe customer’s requirement is to use PU (polyurethane) material to ensure that the sealant has sufficient hardness and waterproofness to cope with high-pressure environments at a depth of 100 meters underwater. This demand places high standards on sealing materials:▶ Stability under high pressure environment: A depth of 100 meters underwater means that the cable will withstand high water pressure, so the sealing material must have excellent compressive strength and be able to withstand deformation or loss of function for a long time of use.▶ Waterproof and moisture-proof: The underwater environment has sufficient moisture, and the material must be effectively waterproof and moisture-proof, with extremely low water absorption to avoid material degradation after prolonged immersion.▶ Good adhesion: The sealing material needs to have good adhesion to the metal or plastic substrate outside the cable to ensure long-lasting and stable sealing effect.▶ Environmental protection and operability: Due to the high environmental requirements of underwater operations, it is particularly important to choose non-toxic and heavy metal free environmentally friendly materials. Moreover, the operability on site also needs to consider the process requirements and application convenience.To address the above challenges, Yilian recommends using the PUR 1661 series products (PUR 1661A/B), which is a two-component solvent-free polyurethane elastomer resin designed specifically for sealing, filling, and other fields.PUR 1661： Ideal sealing material for…
