As electronic devices are increasingly used in demanding environments such as high temperatures, high humidity, and strong vibrations, higher requirements are placed on the durability and safety of packaging materials. The addition-cure potting compound series LSR 3101G/3102G, with its excellent temperature resistance range, flame retardant properties, and stable electrical characteristics, has become a reliable choice for harsh operating conditions.
This product series offers a wide operating temperature range (-50°C to 250°C), maintaining elasticity and insulation performance in extremely cold or high-temperature environments without cracking or deformation due to temperature changes. It is suitable for applications such as engine compartment electronics, outdoor communication equipment, and industrial heating control systems.
In terms of safety performance, the product achieves a flame retardancy rating of UL94-V0 or V1, effectively inhibiting flame spread and enhancing the overall safety level of the equipment. Its waterproof rating is IPX6, enabling it to withstand strong water spray environments and protect internal circuits from moisture erosion.
Regarding electrical performance, the product offers high insulation strength (breakdown voltage ≥20 KV/mm) and stable dielectric properties (dielectric constant 2.7–3.3), with extremely low dielectric loss, ensuring undistorted signal transmission in complex electromagnetic environments. Its thermal conductivity of ≥0.8 W/m·K aids in heat dissipation from high-heat-generating components.
The product series has a hardness of 50±5 Shore A, with a strong and tough structure, and excellent resistance to vibration and impact. Its 1:1 mixing ratio simplifies the application process, with a working time of 35–45 minutes and a curing time of 5–7 hours, making it suitable for medium to large-scale production.
From new energy vehicle electronic controls to energy storage systems, and from industrial inverters to outdoor monitoring equipment, this addition-cure potting compound provides durable and stable protection for electronic components in environments characterized by high temperatures, high humidity, and strong vibrations.
