PVC Foam Industry News & Technical Updates

Autoclave curing combines controlled heat and pressure with a vacuum-bagged laminate. This guide explains process qualification for PVC sandwich cores, including why P200’s documented 4.8 MPa compressive strength does not define its allowable cure pressure.

Closed-cell PVC foam supports lightweight sandwich construction across marine, wind and transport applications. Explore documented StruCell® grades starting at 48 kg/m³, moisture and processing limits, and a practical material-validation checklist.

Selecting a PVC foam core for buoyancy is a pressure calculation: density sets the working depth, and water absorption sets how much lift the part keeps. Measured data at 50 m shows P80 deforming by 0.16% with 2.49% water uptake, while P60 deforms by 8.88% at the same pressure.

PVC foam board (Sunboard, Celuka board) and structural PVC foam core share the same polymer and closed-cell look, but they are made by different processes and are not interchangeable. This guide compares extruded advertising-grade board with moulded, cross-linked structural core on process, density, strength, heat resistance, water absorption and resin compatibility, and explains which applications each one suits. It also lists the StruCell structural PVC foam core grades from 48 to 300 kg/m3 with sheet sizes, thicknesses and surface options.

When you design load-bearing composite panels, you need a high-strength, cross-linked PVC foam core. This closed-cell material effortlessly handles heavy shear, bending, and compression forces. Conversely, you use standard PVC foam board—an un-cross-linked, heavily filled plastic sheet—strictly for

Discover the engineering mechanics behind the composite sandwich panel structure. Learn how separating high-strength outer skins with a lightweight PVC foam core maximizes bending stiffness and delivers an exceptional strength-to-weight ratio for marine, wind energy, and industrial applications without compromising structural stability.

This article explores the strategic advantages of pairing PVC foam core with carbon fiber in wind turbine blade manufacturing. Highlighting UNION’s StruCell® PVC Foam Core, the post details how the material's closed-cell structure delivers an exceptional strength-to-weight ratio, ultra-low resin absorption (<1.5%), and outstanding fatigue resistance. By integrating PVC foam core, manufacturers can significantly enhance aerodynamic efficiency and environmental durability while reducing both blade weight and overall production costs by up to 30%. Backed by DNV GL, ISO 9001, and ASTM certifications, PVC foam core proves to be a reliable, cost-effective, and high-performance solution for modern wind energy projects.

Selecting the right core material is critical for advanced marine composite manufacturing. This article explores the essential parameters engineers verify when choosing a DNV certified marine structural foam, highlighting how rigorous testing, chemical compatibility, and precise density control reduce risks and ensure predictable lamination performance in modern shipbuilding.

Selecting the right PVC Foam Core for vacuum infusion is critical for achieving lightweight, high-strength, and cost-effective composite structures. Success depends on five decisive factors: optimized density (45–250 kg/m³), ultra-high closed-cell content (>95%), minimal resin absorption, exceptional CNC machining tolerance (±0.2mm), and trusted certifications such as DNV-GL. When these elements are properly optimized, PVC Foam Core delivers superior mechanical performance, reduced material costs, and repeatable quality across marine, wind energy, automotive, and drone applications.

Perforated PVC Foam Core sheets are engineered to optimize resin distribution and mechanical interlocking in sandwich panel composites. By creating controlled vertical channels through the closed-cell structure, they ensure superior wet-out, minimize voids, accelerate infusion cycles, and improve overall bond strength. This article examines the science behind different perforation patterns, important performance trade-offs, practical implementation guidance, and proven real-world performance across marine, wind energy, automotive, and drone applications.
