The global PVC foam core market in 2025 continues to expand, driven by:
Increasing demand for larger, lighter rotor blades.
Extensive use in hulls, decks, and superstructures.
Lightweight modules for trains, buses, and EVs.
Shift toward CFC-free, recyclable, low-VOC materials.
Compared to PET or SAN foams, PVC foam cores strike a balance between performance, processability, and cost — making them the most common choice in sandwich composite manufacturing.

JLON, SinoComposites, Gurit APAC — fast-growing manufacturing base with competitive costs.
PVC foam core panels are used in hulls, decks, and bulkheads of high-speed boats and yachts. For instance, JLON CELL foam cores are applied in sandwich hulls for Asian shipbuilders due to their low resin uptake and high fatigue resistance.
PVC cores serve as lightweight reinforcement in rotor blade shells. DIAB’s Divinycell H and Gurit’s PVC series are standard in several 60–80m class blades.
Lightweight interior panels in trains and buses often use PVC core composites, reducing weight by up to 30% compared to plywood alternatives.
Choose density according to design stiffness and load.
Confirm heat resistance for processes over 100 °C (e.g., prepreg curing).
Always request mechanical test data and third-party certificates (DNV, ISO).
Evaluate machining & bonding compatibility for your resin system.
For high-volume or OEM use → DIAB, Gurit, 3A Composites.
For customized or cost-efficient production → JLON, SinoComposites.
For small projects or prototyping → Easy Composites, CoreLite.
In 2025, PVC foam cores remain the dominant structural core material for lightweight composites, balancing performance, processability, and cost. With ongoing innovation in recycling, automation, and performance optimization, global suppliers — from pioneers like DIAB and 3A Composites to fast-emerging manufacturers like JLON Composite — are redefining the standards of structural efficiency and sustainability for the next decade.
