Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • Thermal Insulation: Designed to provide high-performance thermal insulation for pipes, reducing heat loss/gain in commercial and industrial applications.
  • Material Efficiency: Made of polyisocyanurate (PIR) rigid foam, offering superior thermal resistance (ASTM C591 compliance) and durability for long-term use.

Key features

  • 1. Material Technology

    • With polyisocyanurate rigid foam, you can achieve superior thermal resistance and corrosion resistance compared to traditional fiberglass or foam insulation*. The material’s closed-cell structure ensures long-term durability in harsh environmental conditions.

  • 2. Performance Parameters

    • With an R-value of up to 8.3 per inch (per ASTM C518), you can reduce heat loss by up to 30% compared to standard fiberglass insulation*. This high thermal efficiency makes it ideal for maintaining temperature stability in critical systems.

  • 3. Certification Standards

    • With certifications like CE, ASTM C591, and DNV, you can ensure compliance with global safety and performance regulations for industrial and commercial applications*. These standards validate its reliability in demanding environments.

  • 4. Scenario Solutions

    • With a pre-formed cylindrical design, you can achieve seamless installation on pipes of varying diameters, minimizing gaps and thermal bridging*. Its rigid structure ensures stability in both residential and industrial settings, from HVAC systems to chemical processing plants.

  • 5. Durability & Compatibility

    • With corrosion-resistant foam and a smooth surface finish, you can extend equipment lifespan by protecting pipes from moisture and environmental degradation*. The material’s compatibility with diverse substrates ensures broad application flexibility.
