Plastic materials are lightweight, corrosion resistant, and durable, which makes them excellent choices for use in marine ROVs. Curbell Plastics understands the challenges associated with designing equipment for marine environments. We supply materials that deliver the best performance for underwater vehicle applications.
Plastics commonly used in ROV and subsea applications:
Plastics can be thermoformed or easily machined into components for subsea equipment. Frames, thruster nozzles, camera lens domes, and other fabricated parts are capable of tolerating extended periods in either fresh or salt water when fashioned from the right plastic.
Polymers can be used to insulate electronics and some plastics are transparent to the RF signals used for wireless control of ROVs. Plastic materials are available in formulations with low friction and long wear life. Friction and wear grade plastics do not require external lubrication and they are gentle on mating metal parts such as claws.
These properties can increase the performance of marine ROVs.

Advantages of plastic materials for Marine ROVs
Some plastic materials are inherently UV stable and some are available with additives that extend their life in outdoor applications.
A properly weighted ROV can make a difference in performance. Lightweight plastic can help offset the weight of metal components. When neutral buoyancy is achieved, energy efficiency increases.
Capture what’s under the water’s surface with a crystal-clear acrylic camera lens dome. Acrylic domes provide the optical clarity needed as a lightweight but sturdy glass alternative.
ROVs are expected to sustain mild impacts from transportation, handling, and collisions during underwater navigation. Frames built from durable plastics can withstand low impact from bumps and minor collisions with reefs and underwater equipment.
Underwater applications require special consideration when choosing materials. Most (but not all) plastics have low water absorption and maintain their mechanical properties in marine environments.
Plastics can help make ROVs more affordable and cut the weight, helping ease the overall cost of mobilizing an ROV.
ROVs are often manufactured from engineering thermoplastics, many of which can be recyclable at the end of the vehicle’s service life.
