Description

Our n-Pentane / Isopentane (50/50) Blowing Agent Blend is a balanced, high-purity hydrocarbon foaming agent specifically engineered for expandable polystyrene (EPS) and rigid polyurethane (PU) foam manufacturing.

Formulated with an equal 50% n-Pentane and 50% Isopentane ratio, this blend offers ideal pre-expansion speed and uniform cell density control, enhancing the thermal insulation and dimensional stability of final foam products.

Key Features & Benefits

  • Balanced Expansion Rate: Equal blend ratio ensures stable foam expansion and excellent cell structure.
  • Eco-Friendly Blowing Agent: Zero Ozone Depletion Potential (ODP) and ultra-low Global Warming Potential (GWP).
  • High EPS Efficiency: Improves block integrity, surface smoothness, and processing speed in EPS molding.
  • High Purity Quality: Manufactured under strict process controls to guarantee low non-volatile residue.

Main Applications

  • Expandable Polystyrene (EPS) beads and block molding
  • Rigid Polyurethane (PU) insulation boards and panels
  • Structural and packaging foam solutions
