What it is

So Sponge is a startup born from academic research at a higher education institution in Lyon, France. It specializes in passive humidity regulation and anti-condensation solutions built on its patented SRD mesoporous aluminum oxide material, with a core focus on solving internal condensation caused by thermal breathing in sealed electronic enclosures rated IP65 and above. It offers off-the-shelf products and custom R&D services for industrial clients.

Core Features & Pricing

So Sponge currently has two mature finished products on the market:

• AS-B: A self-adhesive anti-condensation patch designed for small-to-medium sized enclosures, which sticks directly to the inner wall of the enclosure and installs in 10 seconds.
• AS-C: A custom dehumidification tape sized for large industrial cabinets.

Multiple active dehumidification products are still in development. The brand also offers professional R&D services, including condensation risk assessment, custom product sizing, temperature and humidity behavior modeling, on-site testing, and more.

Pricing follows a custom quotation model with no public unified pricing. The official website provides an ROI calculation tool, so clients can estimate their return on investment based on their specific use case.

Pros & Cons Analysis

The core advantage is that its innovative technology directly targets a long-standing pain point in the industry:

• Compared to traditional silica gel desiccants, SRD material can spontaneously regenerate in cycles, never becomes saturated, delivers 8 times the effective capacity of silica gel, requires no replacement or maintenance, and has an unlimited service life.
• Compared to heated dehumidification solutions, it consumes no energy at all, has extremely low long-term operating costs, and does not introduce additional points of failure.

The downsides are that currently only a small range of finished products are available for purchase, most product lines are still under development, brand recognition is low, there are no service outlets in China, and the website only supports English and French, which is not user-friendly for domestic Chinese users.

Suitable Users & Accessibility in China

The website can be accessed directly without a VPN in China. It is a great resource for Chinese domestic enterprises with long-term moisture protection needs for outdoor sealed equipment, such as outdoor IoT device manufacturers, industrial electrical enclosure producers, and outdoor infrastructure integrators.
