# LSR Waterproof Seal For Smart Street Light Controller
*Manufactured by 橡楚（湖北）橡胶有限公司*
---
The LSR Waterproof Seal for Smart Street Light Controller is a precision-molded liquid silicone rubber sealing component designed specifically to protect sensitive street light control electronics from outdoor environmental hazards. As a specialized manufacturer of Liquid Silicone Rubber (LSR) products based in Hubei, China, 橡楚（湖北）橡胶有限公司 (Xiangchu (Hubei) Rubber Co., Ltd.) develops this seal to meet the demanding performance requirements of outdoor smart street lighting infrastructure.
Smart street light controllers rely on sensitive circuit boards, communication modules, and power connections that must remain dry and free of contamination to maintain consistent connectivity, dimming control, and remote monitoring functionality. Our LSR waterproof seal provides long-term environmental sealing between the controller housing and enclosure cover, preventing ingress of water, dust, moisture, and road contaminants while maintaining elastic performance across extreme temperature fluctuations common to outdoor installations.
This product is manufactured using food-contact grade liquid silicone rubber (options available) through precision injection molding, ensuring consistent dimensions and tight tolerances that match standard smart street light controller housing designs. Unlike traditional rubber seals, our LSR formulation resists UV degradation, ozone aging, and thermal cycling, delivering a projected service life matching the 10+ year design life of modern smart street light systems.

Our LSR waterproof seal is produced from high-purity addition-cure liquid silicone rubber with the following base material properties:
Finished seals undergo quality testing to confirm the following physical performance characteristics:
Precision injection molding is used to ensure consistent part quality:

Unlike organic rubber compounds that crack, harden, or degrade after 3 – 5 years of outdoor exposure, our addition-cure LSR formulation retains over 80% of its original elongation and hardness after 1000 hours of accelerated UV and weather testing. This resistance to ozone, UV radiation, and temperature cycling eliminates the need for premature seal replacement, reducing maintenance costs for street lighting networks.
LSR maintains consistent elastic compression even after long-term compression, resulting in a low compression set that ensures the seal stays tightly seated between housing flanges. This prevents water ingress even after repeated thermal expansion and contraction of the aluminum or plastic controller housing, maintaining IP67 protection rating for the full service life of the controller.
Our precision injection molding process achieves tight dimensional tolerances that match standard smart street light controller enclosure designs, eliminating fitting issues during assembly. We can also produce custom-sized seals to match non-standard housing dimensions, with low tooling costs for medium and high volume orders.
All base LSR materials are RoHS and REACH compliant, with optional food-contact and medical-grade formulations available. LSR does not leach harmful chemicals into the environment when exposed to rain, making it suitable for public infrastructure installations.
