Rotationally molded marine products offer rugged, seamless, and low-maintenance performance in harsh aquatic environments. One-piece hollow bodies provide inherent buoyancy and impact tolerance, while UV-stabilized polymers resist saltwater, fouling, and weathering over long service lives.
APPLICATION
- Navigation, channel, and marker buoys
- Pipe/instrumentation floats; hose and cable support floats
- Recreational watercraft (rotomolded kayaks, sit-on-tops, canoes)
- Oil-spill containment booms and barrier floats
BENEFITS
- Seamless, leak-resistant construction with uniform wall thickness
- High impact and abrasion resistance; low maintenance
- UV, salt, and chemical resistance for long-term durability
- Design flexibility for colors, outfitting, foam-filling, and ballast options
- Lightweight for easy transport, launch, and recovery; field-repairable
TYPICAL MATERIALS
Marine-grade LLDPE/MDPE (UV-stabilized), HDPE for higher stiffness; optional foam-filled cores (PU/PE) for fail-safe buoyancy; stainless/galvanized hardware interfaces.
OUR ROLE
Diamer act as both a materials supplier (marine-grade resins, color and additive masterbatches, fittings) and a design/manufacturing partner for custom rotomolded buoys, floats, and kayaks.
