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…

How to choose reverse radar sealant? PUR 1670 provides comprehensive protection for your radar system

2024-12-31

With the development of the automotive industry, reverse radar, as an important technology to improve driving safety, has become a standard configuration for modern cars. The reversing radar system detects obstacles behind through sound wave reflection, promptly alerting the driver, reducing blind spots during reversing, and improving driving safety and convenience. However, with the continuous advancement of automotive technology, reverse radar systems not only need to have accurate detection functions, but also face more stringent working environments and increasing durability requirements. In order to ensure the stability and long-term reliability of the reverse radar in various complex environments, the application of sealant has become increasingly important. The working environment and requirements of reverse radarThe reverse radar system is usually installed on the rear bumper of a car, especially the radar sensor part, which is directly exposed to the external environment. These sensors must operate normally under different climatic conditions, whether in high temperatures, hot summers, cold winters, or even harsh weather conditions such as rain, snow, and freezing, they need to maintain high reliability and stability.In order to ensure the long-term effective operation of the sensor, the electronic components of the reverse radar need to be packaged and protected. This is because:Moisture protection: Radar sensors are susceptible to external environmental factors such as rain, snow, and moisture, which can cause short circuits or damage to the circuit board.Shock and pressure resistance: Radar sensors are subject to varying degrees of mechanical impact and vibration, especially during parking or reversing, which may cause damage to the sensors.High temperature resistance: In the high-temperature environment outside the car, electronic components need to be able to withstand sustained high temperatures without affecting performance.PUR 1670A/B is a two-component solvent-free room temperature or heat cured resin elastomer composite used in two-component sealing, filling, flame retardant, thermal conductivity…
