Elliott Company of Indianapolis (Indianapolis, Ind., U.S.) is showcasing its Elfoam rigid polyisocyanurate foam core materials. Elfoam is a rigid, unfaced, closed-cell foam combining low weight, structural integrity, thermal efficiency, fire and chemical resistance, and machinability for composite and industrial applications.
CAMX attendees can view five Elfoam grades — P200, P250, P300, P400 and P600 — with nominal densities from 2.0 to 6.0 lb/ft³ and compressive strengths from 27-142 psi, giving engineers and fabricators a range of options to balance weight, strength, insulation and processing needs for a given application.
The material’s thermal and environmental specifications include an R-value of up to 6.0 per inch, a service temperature range spanning cryogenic conditions to 300°F and a Class 1 flammability rating. Its closed-cell structure is designed to provide moisture resistance and long-term dimensional stability, while its machinability supports fabrication of prototypes, tooling and molds.
Elfoam is available as blocks, sheets and custom-fabricated shapes, and can be delivered pre-cut to specified dimensions and contours; this is intended to reduce in-house machining, material handling, scrap and overall build time. Elliott supports needs ranging from rapid prototypes and one-off components to high-volume, repeat production programs.
Applications for Elfoam span sandwich panels, pultruded and resin-infused structures, fiber-reinforced polymer (FRP) tanks and shelters, industrial and commercial doors, truck and trailer bodies, shipping containers, railcars, marine structures and refrigerated transportation systems, as well as pipe, tank and vessel insulation, environmental test chambers and cold storage systems.
The company has produced Elfoam products since 1957 and works with OEMs, engineers and fabricators on material selection and fabrication strategies. CAMX attendees are invited to meet the company’s technical team to discuss performance goals, processing requirements and application challenges.
