CNC Custom Foam

UNION COMPOSITES' DNV GL-certified StruCell® structural PVC foam provides superior buoyancy solutions for demanding marine applications like ROVs, AUVs, and offshore platforms. This closed-cell (>95%) rigid PVC foam offers exceptional strength-to-weight ratios (45-250kg/m³ densities) with 6.2MPa compressive strength for deep-sea pressure resistance. CNC-machinable for custom geometries, it features <1.5% water absorption, corrosion resistance, and thermal stability (-50°C to +80°C). Ideal for submersible housings, ship hulls, and buoyancy modules, our marine-grade PVC foam outperforms traditional materials with optimized weight reduction and long-term durability in harsh saltwater environments.

UNION's rigid structural PVC foam boards revolutionize campervan and motorhome construction, offering superior performance versus traditional plywood and aluminum honeycomb. As a DNV GL-certified core material, our closed-cell PVC foam provides 50% weight reduction, 100% waterproof protection, and CNC-ready machinability for precision RV interiors. Ideal for walls, ceilings, flooring, and cabinetry, these marine-grade panels deliver unmatched thermal insulation (0.035–0.055 W/m·K), UV resistance, and fire-retardant properties (UL94 V-0). Trusted by Australian RV builders for extreme climate durability. Request free samples for your conversion project.

UNION COMPOSITES' V-Groove Scrim Board PVC rigid foam revolutionizes catamaran tunnel design with its patented wave-damping structure. This marine-grade rigid foam features precision-cut V-grooves and fiberglass scrim reinforcement, reducing hull drag by up to 15% while maintaining DNV GL-certified buoyancy stability. Engineered for high-speed catamarans, the closed-cell PVC core (60-130kg/m³ densities) combines <1.5% water absorption with exceptional compression resistance (up to 3.0MPa). Ideal for tunnel reinforcement and hydrodynamic optimization, our CNC-machined panels are trusted by naval architects for competitive sailing vessels and passenger ferries.
