Sandwich Panel GFRP/PVC Foam Core
Verifiedcomposite· GFRP Foam Sandwich· Divinycell Sandwich
A lightweight sandwich composite consisting of thin E-glass/polyester skins bonded to a rigid PVC foam core (Divinycell H80), manufactured via vacuum-assisted resin transfer molding (VARTM) at room temperature. This class of material combines the corrosion resistance and workability of polyester/vinylester matrices with the structural efficiency of closed-cell foam, creating a high strength-to-weight panel suitable for marine and aerospace environments. Engineers select this sandwich construction when bending stiffness and impact resistance are critical but weight must be minimized, making it a practical alternative to solid laminates or heavier structural foams in cost-sensitive applications.

Regulatory Screening
Environmental
RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
