General Plastics LAST-A-FOAM® FR-3740 Polyurethane Foam
Categories:	Other Engineering Material; Composite Core Material; Polymer; Thermoset; Polyurethane, TS; Thermoset Polyurethane Foam, Unreinforced
Material Notes:	Product Description: LAST-A-FOAM® FR-3700 is a CFC-free, rigid, closed-cell, flame-retardant polyurethane foam available in densities ranging from 3 to 40 pounds per cubic foot. Tougher and less friable than our FR-6700 series, this aerospace-grade, BMS 8-133-qualified foam enables cutting of crisper edges, making it well-suited to machining complex shapes for composite cores. It exhibits a high strength-to-weight ratio due to its cellular structure and cross-linked resin. Because of its closed-cell structure, LAST-A-FOAM® FR-3700 has excellent resistance to water absorption and will not swell, crack, or split on exposure to water. LAST-A-FOAM® FR-3700 provides exceptional protection for hazardous cargo and payloads as an impact- and fire-insulation liner in transport or packaging containers. It also serves as human bone test media. Features: Stable Inert Resistant to most chemicals and solvents Easily shaped with common woodworking tools Performs well as wood replacement Will not support fungal growth Applications: Models and design prototypes Composite Core Honeycomb edge close-out for aircraft interior sandwich panels used in overhead storage bins, passenger cabin class dividers, galleys and lavatories Vacuum form dies and mold patterns Information provided by General Plastics Manufacturing Company
