Hard Foam

LAST-A-FOAM® rigid CFC-free polyurethane foam boards and products are cost-effective, versatile, strong and durable. They are manufactured using our unique chemical formulas to be exceptionally uniform and consistent in all physical properties. You will find a wide spectrum of formulations in multiple densities.

Polyurethane Foam Sheets & Blocks

Our high-density, flame-retardant, marine and rigid polyurethane foams are also available in a broad range of physical forms, including rigid foam boards and blocks. This allows us to best align HDU foam properties with your specific needs – and help you contain material and manufacturing costs.


SUBMERSIBLE FOAM SERIES Hydrostatic pressure-resistant foams provide buoyancy for underwater flotation applications without liquid penetration. They are also used as core material in resin-transfer molding.


PERFORMANCE CORE SERIES Tough BMS 8-133-qualified foam cuts crisply for machining complex shapes. It also serves as impact- and fire-insulation liners for hazardous material, and as human bone-test media.

FR-3800 FST

PERFORMANCE CORE SERIESThis rigid foam core material satisfies fire, smoke and toxicity (FST), and heat release requirements for aerospace applications.


THERMOFORMABLE BOARD SERIES These foam boards are ideal for composite panel cores and other structures where compound-curved surfaces or other details can be made with common thermo-forming methods.


TOOLING BOARD SERIESTough, grain-free machineable boards for styling, design and master models, composite/layout tool masters, and pattern making. An optimal wood alternative for outdoor signage and displays.


MICROCELL SERIES These foam boards are ideal for precision tooling applications, or as modeling foam. Advanced microcell technology creates a grain-free, ultra smooth exterior for painted finishes, significantly reducing process time.


HIGH-TEMP TOOLING BOARD SERIES Supports prepreg composite layout tooling for high-temperature applications up to 400ºF. Ideal for prototype machining, vacuum forming, pattern making, and limited-run tooling.


AEROSPACE GRADE SERIES Flame-retardant foam for aircraft composite core withstands processing up to 250ºF. Superb for models and design prototypes, vacuum-form dies and mold patterns, honeycomb edge closeout.


MULTI-USE CORE SERIES Uniform foam is easily finished or painted for low-cost core applications, hand-carved models, prototypes, CNC-machined topographical maps, composite layup tools, industrial patterns.


STRUCTURAL THERMAL INSULATION BLOCK SERIESHigh-density urethane cellular foam combines high compressive strength with little deflection and extraordinary thermal insulation to support heavy structural loads. Ideal for construction uses.


Structural strength with moisture resistance offers boat designers a top-quality, non-decaying wood alternative that is fully compatible with fiberglass-laminating production methods.
