What is Jloncell PVC Foam Core
PVC foam core is a closed-cell, rigid structural foam core material widely used in composite sandwich structures, including marine foam core, drone foam, boat deck core material, and other high-performance applications. As a high-performance PVC foam core, it is manufactured from cross-linked polyvinyl chloride, offering excellent mechanical properties, lightweight structure, and long-term durability.
The PVC foam core features a uniform, closed-cell structure, providing outstanding resistance to water absorption, chemicals, and fatigue. Its high strength-to-weight ratio makes it ideal for applications like foam core boat building, marine structural foam core, and corecell foam, where lightweight and high stiffness are critical.
As a versatile structural foam core, PVC foam core is compatible with various resin systems including polyester, vinyl ester, and epoxy. It can be used in multiple manufacturing processes such as vacuum infusion (VARTM), RTM / LRTM, hand lay-up, and compression molding, making it suitable for foam core boat construction and other composite projects.

How to Select the Right Rigid PVC Foam
| Application | Density (kg/m³) | Typical Use | Engineering Purpose / Notes |
| Marine (Boatbuilding) | 45–60 | - Small racing boats, kayaks - Superstructure of large yachts - Non-structural interior components | Designed for extreme weight reduction. Used in low-load areas to reduce overall vessel weight, improving speed and fuel efficiency. |
| 60–80 | - Hull bottom and deck of small/medium yachts and fishing boats - Sides of workboats - Secondary structures of high-speed boats | Best cost-performance range. Provides an optimal balance between weight reduction and structural strength. Most widely used density range. | |
| 80–130 | - Hull, deck, and sides of large yachts and passenger vessels - Load-bearing bulkheads - Areas supporting heavy equipment (e.g., engine foundations) | Suitable for higher load conditions. Increased density improves compressive and shear strength for larger vessels and harsher environments. | |
| 130–300 | - Critical load-bearing areas in high-performance boats - High point-load zones (mast bases, winch bases) - Local reinforcement inserts | Provides strength and stiffness close to balsa. Ideal for high-load zones while avoiding water absorption and processing issues associated with wood cores. | |
| UAV / Drone | 45–60 | - Equipment bays - Fairings | Primarily used for protection. Highly weight-sensitive applications. |
| 60–80 | - Main fuselage and arms - Fixed-wing wings / lifting surfaces | Provides a balance between lightweight and structural stiffness. ⚠ For high-speed propellers or central wing box structures, PMI foam is recommended. | |
| Wind Turbine Blades | 45–60 | - Trailing edge / aft edge - Blade tip area | Lightweight design reduces blade mass and improves energy efficiency. |
| 60–80 | - Mid shell (blade shell structure) | Provides sufficient stiffness for shell stability. | |
| 80–130 | - Main spar - Shear web | High strength and shear resistance for major load-bearing structures. | |
| — | - Blade root | Typically uses higher-strength balsa for maximum structural performance. |
PVC Foam Processing Options for Composite Manufacturing
| Scheme | Type | Description | Molding Process |
 | Flat Plate | There is no other post-processing. If you want curved surface, you can get it upon treating the flat plate by thermoforming. | Suitable for hand lay-up, compression molding and other processes of the flat plate with sandwich structure. |
 | Scrim Foam | Small squares are formed by cutting on one side of the flat plate in both directions of length and width with gluing fiberglass mesh on the other side. | Suitable for products with curved surfaces. |
 | Double Cuts | Cut both sides of the core material to the extent 55-60% of the thickness and the cutting positions are staggered. The amount of resin absorption is much less than that of scrim foam. | Suitable for the application with small curvature. |
 | Perforated Plate | Perforate holes with diameter of about 2 mm on plates. You can adjust the diameter of holes according to the thickness and density of the core material. Trapped air formed in the process of lamination can be removed from the bottom of the core material by perforating holes. Also, the resins can flow from one side of the core material to the other side. | Suitable for hand lay-up, vacuum infusion, compression molding process to improve the adhesive strength. |
 | Slotted Plate | Guide slots are set on the plate surface. Guide slots can be disposed in length or width direction on one side or both sides of the plate. The groove(s) can work as the flow path of resins and can remove the trapped air when using the resin vacuum infusion lamination process. | Suitable for vacuum infusion and compression molding process to produce products with large area. |
 | Slotted Perforated Plate | 20mm. On the basis of slotted plates, perforate holes with a diameter of 2 mm in the slots that the spacing between every two is 20 mm in the length or the width direction of the plate. | It has features of the two above core materials, suitable for vacuum infusion, compression molding and vacuum bagging process to produce large-scale products. |
