Release time：2022-01-08

Voir has upgraded its technical protection solutions based on radar‑related products, providing more reliable waterproof and dustproof, pressure‑balanced, condensation‑preventing protection for millimeter‑wave radars, LiDARs, and weather radars.

Voir® Fluoropolymer Adhesive Waterproof and Breathable Solution: Technological Iteration and Upgrade—Enhancing the Reliability and Service Life of Millimeter-Wave Radar

The Voir® adhesive‑backed waterproof and breathable solution employs a self‑developed fluoropolymer‑based waterproof and dust‑proof adhesive (FPV001). This adhesive enables the EPTFE waterproof and breathable membrane to bond more effectively and reliably to various housing surfaces, delivering high bonding strength. While ensuring robust adhesion, it also achieves an IPX9‑level waterproof rating, continuously protecting the cavity by balancing internal and external air pressure in radar sensor enclosures. This enhances the reliability and service life of millimeter‑wave radar sealed cavities. The FPV001 fluoropolymer adhesive is specifically designed for bonding fluoropolymer films to other housing materials and is typically used in die‑cut, adhesive‑backed waterproof and breathable products for millimeter‑wave radar sealed cavities.
● Miniature mounting, without altering the original installation method.
● Dustproof, waterproof, and breathable; our proprietary fluoropolymer adhesive delivers waterproof performance that is one order of magnitude more reliable than conventional back-adhesive products.
● Backing films using fluoropolymer adhesives offer a service life of over 8 years and are waterproof with an IPX9 rating. They also deliver outstanding performance under the double‑85 test conditions—85% relative humidity at 85°C.

Voir® SOT-V snap‑on valve anti‑fogging structural solution helps LiDAR reduce fogging.
The Voir® SOT‑V snap‑on valve solution enhances valve breathability through a polymeric sealing material, representing a technological upgrade over the conventional SOT balance valve. In addition to retaining its original functionality, this enhanced breathability feature activates under a specified pressure differential (≥1 kPa), equalizing the pressure between the interior and exterior of the chamber, thereby reducing moisture ingress and inhibiting condensation. The valve incorporates an integrated waterproof, breathable membrane that provides dust‑ and water‑proof protection while effectively shielding against external contaminants such as dust, sand, and salt spray.
● Does not alter the original installation method
● Intake pressure can be customized.
● Waterproof rating up to IPX7
● Operating temperature: -40 ~ 150℃
● Compared with conventional valve body designs, this solution significantly reduces condensation under the same operating conditions, making it the preferred choice for condensation prevention.
● Already adopted and implemented by numerous communication and LiDAR companies.

Voir®ELE Electro‑Dehumidification Solution — Enhancing Meteorological Radar Reliability
Meteorological radars are primarily used to detect weather conditions and their trends, often deployed in areas with significant temperature differences or at high altitudes. In such environments, condensation on the inner walls of the monitoring lens can severely impair image quality. Voir®ELE’s electro‑dehumidification solution employs a self‑developed solid‑state electrode membrane to electrolyze water vapor, reducing the moisture content within the chamber and achieving effective dehumidification. During operation, it continuously electrolyzes humid gases and water droplets inside the chamber into hydrogen and oxygen ions, providing a cutting‑edge, next‑generation micro‑dehumidification technology.
● Active dehumidification, irreversible, unaffected by high or low temperatures.
● Environmentally friendly, low power consumption, and noise-free
● The pressure difference that balances the oxygen consumption due to tidal volume during electrolysis.
● All‑round three‑proof design: water‑proof, pressure‑proof, and overcurrent‑proof
