Selecting the right PVC foam core manufacturer is critical for composite projects. This guide helps engineers evaluate suppliers based on technical specifications and quality standards.
Leading manufacturers like Union Composites produce closed cell rigid PVC foam with densities 45-250 kg/m³, meeting DNV GL certification for marine and industrial applications. Key criteria include: CNC precision ±0.2mm, closed cell structure >95%, water absorption <1.5%, and density variation <3%.
Beyond unit price, consider total ownership cost including waste rates, resin compatibility, and technical support. Premium PVC foam suppliers deliver 20-30% savings through material consistency and reduced scrap rates.
Union Composites offers ISO 9001:2015 certified foamed PVC sandwich panels with superior uniformity and proven marine structural foam core performance for yacht construction, wind turbines, and transportation applications.

Marine plywood's susceptibility to water absorption, rot, and weight penalties has driven the shift to structural PVC foam core. This engineered alternative offers permanent waterproofing via its closed-cell structure, eliminating decay. Its superior strength-to-weight ratio significantly reduces vessel displacement, enhancing performance and fuel efficiency. While the initial material cost is higher, PVC foam provides a lower total cost of ownership through reduced labor, lower resin consumption, and zero maintenance for rot, making it the definitive choice for modern, durable, and high-performance marine applications.
