Blowing Agents

Industrial infographic illustrating pentane blowing agent applications, including appliance insulation (Cyclopentane), construction sandwich panels and spray foam (n-Pentane and Isopentane blends), and EPS/XPS polystyrene foam systems, alongside ISO tank and drum export packaging options.

Junyuan Petroleum Group manufactures high-purity pentane blowing agents and custom-blended formulation systems for rigid polyurethane (PU/PIR) foam, expandable polystyrene (EPS), and extruded polystyrene (XPS) applications. The product range covers pure grades — Cyclopentane, n-Pentane, and Isopentane — along with pentane blends engineered to precise boiling points and vapor pressure profiles for optimal thermal insulation performance.

Main Applications & Product Range

  • Appliance Insulation: Pure Cyclopentane and high-Cyclopentane blends for zero-ODP, ultra-low GWP refrigerator and freezer insulation systems.
  • Construction & Building Boards: n-Pentane, Isopentane, and custom-ratio blends optimized for continuous sandwich panels, PIR block foam, and spray foam formulations.
  • Expandable & Extruded Polystyrene (EPS/XPS): Pentane solvents used as physical blowing agents for packaging and structural insulation boards.

Custom Formulation & Export Packaging

Junyuan offers 20+ standardized and customizable blending options, supporting cell-structure control and density optimization to match specific processing parameters. Products are available for global bulk delivery in ISO tanks (25/26 CBM) or heavy-duty steel drums, backed by full Technical Data Sheets (TDS), MSDS, and export certification.
