LOW K-200 MARINE POLYIMIDE FOAM

Pg-04-5.jpg

Low K-200 is a range of thermal and acoustical insulation products fabricated from lightweight, fire-resistant polyimide foam. Open-cell foam is available for thermal and acoustical hullboard, pipe covering, and transmission-loss treatment. Closed-cell foam is available for anti-sweat hull treatment.

 

APPLICATIONS

  • Shipboard hulls, bulkheads, overheads, and ducts requiring thermal and/or acoustical treatment per DOD-I-24688

  • Submarine hull and frame sections requiring sound transmission-loss treatments. TLT-DB is the U.S. Navy’s approved alternate to MIL-T-24708.

 

FEATURES/BENEFITS

  • Weight reduction: Lightweight polyimide foam offers substantial weight savings.

  • Fewer mechanical fastening devices required

  • Polyimide foam is inherently fire resistant, thus yielding longer burn-through times, low surface-burning characteristics, very low smoke developed, and no significant toxic off-gassing.

  • Full approval by the U.S. Navy

  • Factory-applied facings and jacketings include glass cloth, aluminized mylar, Tuffskin, perforated glass cloth, and others.

  • Improved habitability and increased resistance to abuse and water damage

  • Shipboard chilled-water lines and systems up to 100 °F. Vapor barrier jacketing or lagging is required per MIL-STD 769 and MIL-STD 635.
