PVC Foam Core FAQs
What is PVC Foam Core?
PVC Foam Core is a lightweight, closed-cell polymer material produced by foaming polyvinyl chloride (PVC) resin. It features a honeycomb-like microstructure with over 95% closed-cell rate, offering high strength at low densities (45-250 kg/m³). As a trusted PVC Foam Core supplier, UNION COMPOSITES manufactures StruCell® PVC Foam Core for demanding applications like marine composites and wind turbine blades, providing excellent thermal insulation, chemical resistance, and low water absorption (<1.5% per ASTM D2842).
What are the key advantages of using StruCell® PVC Foam Core over other foam materials?
StruCell® PVC Foam Core stands out with its rigid, load-bearing structure (up to 6.2 MPa compressive strength), ultra-high closed-cell design for minimal resin uptake, and extreme temperature stability (-240°C to +100°C). Unlike standard foams, it offers DNV GL certification, superior fatigue resistance, and CNC machining compatibility, making it a cost-effective choice for marine, automotive, and aviation projects—saving 20-30% on material costs compared to EU/US brands.
What densities and thicknesses are available for PVC Foam Core boards?
Our PVC Foam Core boards come in densities from P45 (45 kg/m³) for lightweight insulation to P250 (250 kg/m³) for high-pressure applications. Standard thicknesses range from 2mm to 70mm, with custom options available. We maintain a precise thickness tolerance of ±0.2mm, ensuring consistency for structural PVC foam core in sandwich panels and custom CNC cuts.
What surface treatments do you offer for PVC Foam Core?
We provide a variety of surface treatments for PVC Foam Core, including plain boards, punched boards, one- or two-sided grooved boards, grooved and punched options, scrim boards, scrim and punched boards, hyperbolic boards, and hyperbolic punching plates. Custom treatments are available to enhance bonding, resin flow, and performance in applications like boat building or GRP/FRP fiberglass sandwich panels.
How does PVC Foam Core perform in marine environments?
UNION's marine-grade PVC Foam Core is DNV GL-certified for saltwater resistance and UV stability, with <1.5% water absorption. It's ideal for boat hulls, decks, bulkheads, and ROV buoyancy foam, offering superior strength-to-weight ratios and corrosion resistance compared to traditional materials like balsa wood.
What is the delivery time and MOQ for PVC Foam Core orders?
We offer fast delivery: 5-7 days for small orders and 15-20 days for full containers. There is no minimum order quantity (MOQ), and we provide free A4 samples to help you test our PVC Foam Core. Global shipping includes FCL/LCL options with AEO-accredited customs clearance in over 30 countries.
Is PVC Foam Core environmentally friendly and recyclable?
Yes, our PVC Foam Core is recyclable and complies with eco-friendly standards, unlike some foams that produce microplastics. It's designed for long-term durability (3-5x lifespan of alternatives), reducing waste in applications like wind energy and automotive manufacturing.
