Rigid Polyurethane Foam Products
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. Our rigid foam materials are available in sheets or blocks.
Our high-density, flame-retardant, marine and rigid polyurethane foams are also available in a broad range of physical forms, including rigid and hard 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.

LAST-A-FOAM® RIGID FOAM SHEETS & BLOCKS
Advanced dielectric foam material for use in radomes, antennas and other radio frequency (RF) communication systems. RF-2200 addresses the need for an RF-transparent protective layer with extended thermal processing capabilities.
Subsea | Composite Core
Hydrostatic pressure-resistant foams provide buoyancy for underwater flotation applications without liquid penetration. They are also used as core material in resin-transfer molding.
Aerospace | Composite Core | Dielectric | Marine | Nuclear | Medical
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.
Aerospace | Composite Core
This rigid foam core material satisfies fire, smoke and toxicity (FST), and heat release requirements for aerospace applications.
Composite Core | Sports & Recreation
These foam boards are ideal for composite panel cores and other structures where compound-curved surfaces or other details can be made with common thermoforming methods.
Aerospace | Dielectric | Marine | Medical | Prototypyes | Tooling/Molds
Tough, grain-free machinable boards for styling, design and master models, composite/layout tool masters, and pattern making. An optimal wood alternative for outdoor signage and displays.
Marine | Tooling/Molds | Prototypes and Models
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.
Tooling & Molds
FR-4800 is a high-temperature tooling board with low CTE that can be used with high-temperature resin systems, such as vinyl esters, epoxies, and BMIs, in high-pressure autoclaves and fiber-reinforced composites.
Aerospace | Marine | Tooling/Molds
Supports prepreg composite layout tooling for high-temperature applications up to 400F. Ideal for prototype machining, vacuum forming, pattern making and limited-run tooling.
Composite Core | Construction | Dielectric | Marine | Prototypes | Sports/Recreation | Subsea | Tooling/Molds
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.
Aerospace | Composite Core | Marine | Sports/Recreation | Subsea
Flame-retardant foam for aircraft composite core withstands processing up to 250°F. Superb for models and design prototypes, vacuum-form dies and mold patterns, honeycomb edge closeout.
High-density urethane cellular foam combines high compressive strength with little deflection and extraordinary thermal insulation to support heavy structural loads. Ideal for construction uses.
Marine | Subsea
Structural strength with moisture resistance offers boat designers a top-quality, non-decaying wood alternative that is fully compatible with fiberglass-laminating production methods.
