PVCschuimpllagen

PVC schuimpllagen are layers made from polyvinyl chloride foam (PVC foam) that serve as lightweight cores in various products. The foam is produced by incorporating blowing agents into PVC resin, creating a relatively rigid, closed-cell structure with low density. Depending on formulation, the foam can be used as a rigid or semi-rigid core in sandwich panels or as a standalone foam sheet.

Key properties include low weight, good thermal insulation, and sound dampening. The closed-cell nature gives moisture resistance and relatively good dimensional stability, while surfaces can be laminated or bonded to skins such as wood, metal, or solid PVC. Foam densities for these layers typically range from low to mid densities, with thicknesses from fractions of a millimeter to several millimeters, depending on the application.

Common applications of PVC schuimpllagen include insulation cores in architectural and industrial sandwich panels, underlayment for flooring, packaging cushioning, and lightweight automotive or furniture components. They are often bonded between outer skins using compatible adhesives and may be produced by extrusion or calendering processes.

Processing and handling considerations include ensuring good bonding between the foam and skins, controlling surface finish, and selecting compatible stabilizers and additives for heat and weather exposure. Environmental considerations involve the chlorine content of PVC; recycling and proper end-of-life management are important, with possibilities for regrinding and reprocessing into new foam products.

Advantages of PVC schuimplagen are light weight, good insulation and damping, and ease of fabrication; limitations include relatively lower heat resistance, potential flammability concerns, and environmental impacts associated with PVC.
