Product Description

This series of rubber plug products are mainly made of NBR (nitrile rubber), suitable for sealing and protecting holes such as charging ports, sensors, etc. of underwater robots during operation, with excellent sealing performance and chemical corrosion resistance, adapting to various water quality environments. Supporting customization of specifications, structure and hardness.

PRODUCT FUNCTION

This rubber plug has multiple functions such as sealing and waterproofing, corrosion resistance and structural stability. It can effectively block liquids and impurities from entering the orifices in complex underwater environments, protect electronic components from damage, and enhance the operational safety and reliability of underwater equipment.

PERFORMANCE INDEX

Chemical corrosion resistance: After being immersed in media such as residual chlorine, copper sulfate, flocculant, acids and alkalis, sodium hypochlorite for 30 days, the performance retention is ≥80% and the volume change is ≤15%;

UV resistance: After 168 hours of UV irradiation, the performance retention is ≥80%;

Ozone aging resistance: No cracks on the surface after 72 hours of testing;

High and low temperature cycle resistance: After 6 temperature cycles from -20℃ to 60℃, dimensional stability is maintained with no abnormalities.

APPLICATION AREA

The charging port plug is Widely used in underwater robots, underwater detection equipment, submersibles, aquaculture automation devices and other scenarios with high requirements for hole sealing, suitable for waterproof sealing and protection of parts such as charging ports, interfaces, sensor bases, redundant holes, etc.
