Cost-Saving Premium Quality
UNION delivers TOP 3 global quality at 20-30% lower cost vs EU/US brands.
A fiberglass sandwich panel is a composite structure with outer GRP/FRP skins bonded to a central PVC foam core, providing rigidity without added weight. UNION's panels use our high-performance StruCell® structural PVC foam core, which ensures the sandwich panel maintains integrity under load, flex, or moisture exposure.
Our panels achieve neutral weight balance in structural applications, with core densities from 60–200 kg/m³ optimized for stiffness and insulation. The closed-cell PVC foam core limits water absorption to <0.5% (ASTM D2842), preserving panel performance over decades. As a PVC foam core supplier, we assemble full panels or supply CNC-machined cores for your lamination process, cutting production time.
High Strength and Low Weight: GRP/FRP skins (2–5mm thick) over PVC foam core reduce panel weight by 50% vs. solid fiberglass, boosting fuel efficiency in vehicles.
Closed-Cell Structure: StruCell® structural foam core resists compression up to 3.5 MPa, preventing delamination in high-stress zones.
Corrosion Resistance: FRP/GRP surfaces and hydrolysis-resistant PVC foam core withstand saltwater, chemicals, and UV for marine-grade durability.
CNC Machining Precision: Custom contours with ±0.1mm tolerances for complex grp composite panels, ready for direct installation.
Thermal Insulation: Low conductivity (0.03 W/m·K) from the PVC foam core suits refrigerated or insulated applications.
Waterproof & Rot-Proof: Unlike wood-core panels, our closed-cell PVC foam core (<1% water absorption) prevents delamination, osmosis, and rot, ensuring a maintenance-free lifespan.
Superior Stiffness & Strength: The structural foam core handles shear loads effectively, preventing panel buckling under stress.
Core Densities: P45 to P300 for tailored stiffness.
Skin Finishes: Gelcoat, anti-skid, or perforated for bonding.
Panel Sizes: Up to 12m x 2.5m; thicknesses 20–150mm.
Our frp foam core panels excel where weight savings and rigidity matter. The structural PVC foam core provides the shear strength that makes fiberglass sandwich panels suitable for:
· Marine Industry: Bulkheads, decks, hatches, and superstructures for yachts and workboats using marine structural foam.
· Transportation: Lightweight walls, floors, and roofs for RVs, campervans, and refrigerated truck bodies.
· Construction: Interior partitions and cladding—GRP skins offer fire resistance and easy cleanability.
· Industrial: Drone frames, wind energy nacelles, and corrosive environment enclosures requiring robust GRP sandwich panels.
No Minimum Order Quantity (MOQ): We accept prototype and small-batch orders.

Order Confirmation: Verification of panel dimensions, core density (P60-P250), and skin specifications.
Core Preparation: StruCell® PVC foam sheets are CNC machined or grooved to ensure perfect resin flow and bonding.
Lamination: Automated vacuum infusion or continuous lamination process bonds the FRP skins to the structural foam core.
Curing & Cutting: Panels are cured under controlled heat and cut to precise tolerances (±1mm).
Quality Control: Ultrasonic testing for delamination and visual inspection of gelcoat finish.
Global Shipping: Panels are stacked with protective film and corner guards on steel pallets.
