Product Cheat Sheet

LAST-A-FOAM® RF-2200 Rigid Foam
High-performing, RF-transparent protective layer for radomes, antennas and other applications where low dielectric constant and loss tangent are necessary.

LAST-A-FOAM® R-3300 Rigid Foam
Semi-submersible foam engineered to resist water penetration. Optimal for shallow to mid-water (1200 ft.) subsea buoyancy systems, marine and underwater robotics applications. Also used in resin-transfer molding as core material.

LAST-A-FOAM® FR-3700 Rigid Foam
Tough, aerospace-grade foam cuts crisply for machining complex shapes for composite cores. Also serves as impact and fire insulation liners for hazardous material and as human bone-test media.

LAST-A-FOAM® FR-3800 FST Rigid Foam
Halogen-free, lightweight foam core that complies with FST and OSU 65/65 requirements for commercial aircraft interiors. Used in conjunction with other materials, it contributes to both aesthetics and safety, while reducing cost.

LAST-A-FOAM® FR-4300 Rigid Foam
Low-density foam boards ideal for composite panel cores and other structures where compound-curved surfaces or other details can be made with common thermoforming methods.

LAST-A-FOAM® FR-4500 Rigid Foam
High-density, grain-free, machinable foam boards for styling, design and master models, composite/layout tool masters and pattern making. An optimal wood alternative for outdoor signage and displays.

LAST-A-FOAM® FR-4600 Rigid Foam
Ideal for precision tooling applications, prototypes and models or 3D displays. Advanced microcell technology creates a grain-free, ultra-smooth exterior for painted finishes, reducing process time.

LAST-A-FOAM® FR-4700 Rigid Foam
High temperature tooling foam that supports prepreg composite layup tooling for applications up to 400° F. Ideal for prototype machining, vacuum forming, pattern making and limited-run tooling where metallic dies are cost prohibitive.

LAST-A-FOAM® FR-6700 Rigid Foam
Flame-retardant foam for aircraft composite core withstands processing up to 250°F. Superb for galleys, lavatories and honeycomb edge closeout.

LAST-A-FOAM® FR-7100 Rigid Foam
Economical, uniform foam that is easily finished or painted for low-cost core applications, hand-carved models, prototypes, CNC-machined topographical maps, composite layup tools and industrial patterns.

LAST-A-FOAM® R-9300 Rigid Foam
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.

LAST-A-FOAM® R-9800 Rigid Foam
Lightweight yet strong material provides a homogeneous background that is transparent to X-rays. Ideal core panel for X-ray and diagnostic tables, CT scanner beds and as calibration materials.

LAST-A-FOAM® TR-Marine Rigid Foam
Structural strength with moisture resistance offers boat designers a top-quality, non-decaying wood alternative that is fully compatible with fiberglass-laminating production methods.

LAST-A-FOAM® EF-4000 Flexible Foam
Low-density foam formulated to absorb significant vibration while protecting and cushioning payloads. Extremely durable and relatively unharmed by environmental factors.

LAST-A-FOAM® TF-5070 Flexible Foam
Highly resilient, flame-retardant foam used for shock isolation system in construction, impact-mitigating pad shipping containers and vibration-damper pads for mechanical equipment.

LAST-A-FOAM® TF-6070 Flexible Foam
High-density foam designed for shock isolation of heavy objects when the supporting foam will be under long-term static stress.

LAST-A-FOAM® FP-8000 Flexible Foam
Open-cell, fire-resistant foam exhibits high hysteresis as well as excellent recovery from dynamic impacts. Used for aircraft interior crash padding. A low resilience allows foam to absorb most impact energy.

Foam Comb Foam-Filled Honeycomb
Lightweight, flexible foam-filled honeycomb material serves as a multi-purpose aerospace seal and filler. Ideal for interior trim parts and areas that require noise reduction.
