08.2011 (replaces 03.2011) ® BALTEK SBC Certified Select Grade Structural Balsa CHARACTERISTICS Outstanding strength and stiffness to weight ratios First class, select grade lumber, FSC-certified Ecological product, 100% plantation grown Full traceability and highest lumber quality due to strict process control from seedling to final product Extremely wide operating temperature range -212 ° to +163 ° (-414 ° to +325 ° C C F F) Fulfills most FST (flame, smoke, toxicity) requirements Excellent fatigue and impact resistance Good sound and thermal insulation Good moisture resistance APPLICATIONS Marine Hulls, decks, superstructures Road and Rail Floors, roofs, side skirts, front-ends, doors, interiors Wind energy Rotor blades (shear webs & shells), nacelles, spinners Aerospace: Floors, cargo pallets, cargo containers, bulkheads, general aviation (fuselage and wing) Defense Naval vessels, containers, cargo pallets, shelters, ballistic panels Industrial Tanks, containers, architectural panels, infrastructure, impact limiters, sporting goods PROCESSING Adhesive bonding Compression molding Contact molding (hand/spray) Pre-preg processing (up to 180 ° 355 ° C, F) Resin injection (RTM) Vacuum infusion BALTEK® SBC is a core material produced from certified kiln-dried balsa wood in the ‘end-grain’ configuration. Forest Stewardship Council (FSC) Certification ensures that the balsa lumber is sourced from 100% plantation grown trees and that all production steps are tightly monitored. This guarantees full traceability from seedling to the delivered product and that highest quality of balsa is provided. BALTEK® SBC is the only FSCcertified structural balsa core material. SBC has extremely high strength and stiffness to weight ratios and achieves an excellent bond with all types of resins and adhesives. It is compatible with a variety of manufacturing processes and is resistant to temperature changes or exposure to fire and chemicals. BALTEK® SBC is an ideal core material for an extensive range of applications subjected to static or dynamic loads in service. All while FSC-certified as a renewable resource.
