The 2025 Ringier Technology Innovation Awards for the plastics industry have been officially announced, with Elkem Silicones being honored for its innovative liquid silicone rubber material, BLUESIL™ LSR 3935. This product, with its outstanding performance, has addressed the long-standing technical challenge of waterproof sealing in high-voltage connectors for new energy vehicles (NEVs), providing a novel solution for the industry’s high-quality development.
With the growing stringency of safety and reliability requirements for NEV high-voltage systems, the performance of connectors - especially thermal stability and long-term sealing capability under complex operating conditions - has emerged as a critical challenge. Traditional materials, prone to aging-induced sealing failures, have long hindered industry advancement. Leveraging deep technical expertise, Elkem Silicones developed BLUESIL™ LSR 3935, achieving significant breakthroughs through three key innovations: firstly, the material’s self-lubricating surface properties significantly reduce the risk of assembly wear; secondly, its ultra-low compression set ensures long-term stability of the sealing structure; and thirdly, its heat resistance under extreme temperatures effectively copes with high-intensity operating environments. This product line features customizable hardness options to meet varied design specifications, ensuring long-term reliability for NEV high-voltage system safety.
As a leader with decades of silicone technology expertise, Elkem Silicones remains committed to advancing material science and application innovations, facilitating the intelligent transformation across transportation, energy, and electronics industries. This award not only reaffirms its global leadership in silicones but also injects vital momentum into the NEV industry’s pursuit of key technology independence and sustainable development.
