Submersible enclosures play a crucial role in protecting electronic and electrical components from the harsh conditions found in underwater environments. Whether used in marine applications, underwater sensors, or other submerged technologies, the material you use for these enclosures is very important.
As the experts in submersible enclosures, SLAYSON® work with a range of material types, and one in particular has gained prominence for its performance – polyurethane. Read on as we explore why you should choose polyurethane as a preferred material for submersible enclosures.
Exceptional chemical and water resistance of polyurethane
Polyurethane’s inherent ability to create a tight seal ensures that the enclosed electronic components remain dry, safeguarding them from potential damage caused by moisture and water exposure.
Submersible environments can expose enclosures to various chemicals and corrosive substances. Polyurethane’s resistance to a wide range of chemicals makes it an ideal choice for applications where exposure to corrosive elements is a concern. This chemical resistance enhances the longevity of submersible enclosures, ensuring they remain durable in diverse underwater conditions.
Top-tier flexibility and impact resistance
Polyurethane exhibits impressive flexibility and impact resistance, making it resilient against the dynamic forces present in underwater environments. The material can withstand bending, flexing, and impact without losing structural integrity. This flexibility is crucial for submersible enclosures, which may experience external pressures or vibrations during operation.
As polyurethane is lightweight, its buoyancy is advantageous in submersible applications. When designing submersible enclosures, it is essential to consider the weight of the materials used. Polyurethane’s lightweight nature contributes to the overall buoyancy of the enclosure, making it easier to manage and deploy in underwater scenarios.
Have you considered thermal insulation?
The thermal insulation properties of polyurethane help regulate temperature within the enclosure. This is particularly important for electronic components, as extreme temperature variations can adversely affect performance. Polyurethane helps maintain a stable internal temperature, protecting sensitive equipment from heat or cold in underwater environments.
This versatile material can be easily moulded into complex shapes and sizes. This characteristic allows for the customisation of submersible enclosures to fit specific electronic components and design requirements. Manufacturers can create enclosures that precisely match the dimensions and specifications of the equipment they are meant to protect.
Perfect for UV resistance
Ultraviolet (UV) radiation exposure is a common challenge in outdoor and underwater applications. Polyurethane exhibits resistance to UV radiation, ensuring that the material does not degrade or weaken when exposed to sunlight. This UV resistance enhances the overall durability of submersible enclosures, especially those intended for long-term deployment.
SLAYSON®‘s NEMA 6P and IP68 SUBSEA Range
SLAYSON®‘s SUBSEA range of Deep Submersible Enclosures is tailored for applications in renewable energy, submarine exploration, and remotely operated vehicles (ROVs); these enclosures offer the ultimate protection against the harshest marine conditions.
Constructed from a Rigid Polyurethane Composite, these enclosures boast exceptional water resistance and impact resilience. Complemented by corrosion-resistant Stainless Steel type 316 hardware, SLAYSON® ensures longevity even in the face of saltwater exposure, a common challenge in marine applications.
The integrity of the SUBSEA enclosures is guaranteed by a single piece Silicon O-ring, meticulously engineered to provide a watertight seal. This innovative sealing solution protects vital electrical equipment from the ingress of water. It allows for the transmission of acoustic and wireless signals, ensuring seamless communication capabilities in the underwater domain.
Meeting Stringent Standards: NEMA Type 6P, IP67, IP68, IK10 Impact Resistance
The SUBSEA range complies with NEMA Type 6P, ensuring robust protection against environmental factors. With IP67 and IP68 ratings according to IEC 60529, these enclosures are impervious to dust and capable of withstanding prolonged immersion in water up to 262 feet (80 meters).
The enclosures also boast an impressive IK10 Impact Resistance rating, ensuring they can withstand external forces and potential collisions in challenging underwater environments. Crafted with seamless single-mould construction, this range eliminates weak points and enhances structural integrity. This construction method contributes to the enclosures’ robustness and allows for customisation to meet the specific requirements of diverse underwater applications.
Tested against the rigorous ASTM B117 Salt Spray Test, the SUBSEA enclosures demonstrate exceptional corrosion resistance, ensuring reliable performance despite harsh marine elements.
