Core replaces PVC

SP Systems (Isle of Wight, U.K.) has introduced Corecell T-Foam, a structural SAN (styrene acrylonitrile) core designed to replace crosslinked PVC in composite sandwich constructions. Compatible with polyester and epoxy resins, the foam processes to 120°C/248°F, and at 100°C/212°F in use, retains almost 60 percent of

SP Systems (Isle of Wight, U.K.) has introduced Corecell T-Foam, a structural SAN (styrene acrylonitrile) core designed to replace crosslinked PVC in composite sandwich constructions. Compatible with polyester and epoxy resins, the foam processes to 120°C/248°F, and at 100°C/212°F in use, retains almost 60 percent of its room-temperature compressive properties (conventional crosslinked PVC foams retain less than 20 percent), according to the company. Reportedly, T-Foam cored products exposed to temperature variation will better maintain their properties and experience very little core print-through.
