Fine-cell foams for topographical models and maps -Image

LAST-A-FOAM® used for topographical models and maps throughout the world.Topographers enjoy the consistent cell-structure and density of the FR-4500 and FR-7100 foam boards, which makes cutting their models with CNC routers simple and accurate. The fine small cells allow easy paint finishing of completed models, and the dimensional stability of sheets keep models flat and true. Valued in notable institutions worldwide helping people to see and understand topography in a direct and reliable way.

Turn to the company where great ideas take shape.

General Plastics Manufacturing Company has three products lines: rigid foam, flexible foam, and production parts.

Rigid foam is used for composite core, tools, models, and signs.

Flexible foams are for applications where energy absorption, fire retardancy, appearance, and versatility are important.

Production parts are build-to-print composite parts for the military, aerospace, and transportation industries.

We work alongside our customers to find the best product for their needs.
