Overview
Marine Vacuum Insulation Panels | LNG Ship Thermal Insulation

Product Summary
To meet the extreme cryogenic insulation demands of LNG/LPG carriers, Super Tech BPP combines BVP vacuum technology with rigid PIR insulation to deliver armor-grade protection, high-performance cold retention, and efficient installation.

Advantages of BPP Marine Vacuum Insulation Panels

• Armor-Grade Strength (BVP Technology): Protects vacuum level like armor, eliminating leakage and swelling problems common with most VIPs that use barrier film. The rigid base shell is hot formed for excellent resistance to deformation and puncture.
• Superior Cryogenic Insulation (PIR Composite): Uses PIR to offer better physical properties and fire performance than conventional polyurethane; designed for cryogenic environments from -196°C to -100°C.
• Easy Installation: BPP is bonded to the flat insulation board with a low-temperature-resistant adhesive and serves as the primary insulation layer for membrane-type LNG and LPG ship tanks, enabling fast and efficient installation.

Super Tech BPP Product Value

• High Efficiency and Energy Savings: With an extremely low effective thermal conductivity, 40 mm of BPP provides insulation comparable to 100 mm of polyurethane, significantly reducing the daily boil-off rate (BOR) of LNG/LPG.
• Safe, Clean, and Environmentally Friendly: Releases no fiber dust and contains no VOCs, meeting strict marine environmental and safety requirements; offers excellent fire and corrosion resistance.
• More Cargo Space and Lower Operation Cost: Ultra-thin design increases available tank volume, improving cargo capacity and voyage economics.
• Stable Structure and Long Service Life: Stainless-steel enclosure resists aging and puncture; corner deformation and manufacturing processes are tightly controlled and the extremely low overall leak rate ensures stable performance through product life cycle.

Applications

• LNG Carriers: Designed for membrane-type LNG carriers where high space utilization is required.
• LEG Ethylene Carriers: Suitable for fully refrigerated liquid ethylene tanks (-104°C) requiring precise temperature control.
• Floating Storage and Regasification Units (FSRU): Provides reliable protection for offshore floating gas storage under vibration and vessel inclination.
• LPG Carriers: Suitable for fully or semi-refrigerated LPG tanks to reduce energy loss and maintain tank pressure balance and cargo quality.
• Deep-Freeze Refrigerated Vessels: Used in ultra-low-temperature cargo holds (e.g., -60°C) to maximize cargo space and preserve quality over long periods.
• LNG-Fueled Vessels: Insulates LNG fuel tanks and supply lines in compact machinery spaces to meet cryogenic fuel storage standards and support lower-emission shipping.

Caractéristiques / spécifications techniques

• Core technologies: BVP vacuum technology combined with rigid PIR composite insulation.

• Temperature suitability: PIR composite designed for cryogenic environments down to -196°C and up to -100°C operational range indicated for cryogenic application.
• Thermal performance: 40 mm BPP provides insulation comparable to ~100 mm polyurethane (very low effective thermal conductivity).
• Bonding/installation: Bonded to flat insulation board with low-temperature-resistant adhesive; intended as primary insulation layer for membrane-type tanks.
• Enclosure material: Stainless-steel enclosure providing corrosion resistance and long service life.
• Environmental & safety: No fiber dust, no VOCs; improved fire and corrosion resistance compared with conventional options.
• Reliability: Extremely low overall leak rate to ensure stable vacuum performance throughout lifecycle; eliminates typical VIP leakage/swelling issues associated with barrier film.
• Typical use cases: Membrane-type LNG/LPG carriers, LEG ethylene carriers, FSRU, deep-freeze refrigerated vessels, LNG-fueled vessel tanks, other cryogenic shipping applications.
