Pentane (Blowing Agent)
- Product Description
-
- Commodity name: Pentane (Blowing Agent)
Expandable Polystyrene (EPS): Pentane is incorporated into polystyrene beads during the suspension polymerization process. When heated, the pentane vaporizes, expanding the beads into a foam. EPS is widely used in construction (insulation for walls, roofs, and floors), packaging (protective packaging), and various other applications. Polyurethane (PU) Foams: Pentane, particularly cyclopentane, is a key blowing agent for rigid PU foams used in refrigeration and insulation.
Chemical Name:Pentane (Blowing Agent)
Shape:Colorless liquid (for *n-pentane* and *iso-pentane*)
Component:Primary component: Pentane isomers (used as blowing agents in EPS production), n-Pentane (normal pentane)
Other names:
Pentane blend, Foam expansion agent, EPS blowing agent, n-Pentane / iso-Pentane mixture

Application:
Expandable Polystyrene (EPS): Pentane is incorporated into polystyrene beads during the suspension polymerization process.
When heated, the pentane vaporizes, expanding the beads into a foam.
EPS is widely used in construction (insulation for walls, roofs, and floors), packaging (protective packaging), and various other applications.
Polyurethane (PU) Foams: Pentane, particularly cyclopentane, is a key blowing agent for rigid PU foams used in refrigeration and insulation.
It helps achieve high insulation performance in refrigerators and other insulated products.
Pentane is also used in flexible PU foams for applications like cushioning and upholstery.
Other Applications: Pentane is also used in the production of extruded polystyrene (XPS) foam.
It can be used in spray polyurethane foam (SPF) for insulation in hard-to-reach areas or for renovation projects.
The specific type and ratio of pentane isomers can be tailored to optimize the foam's properties for different applications.
Packing:
Steel drums (200 kg)
ISO tank containers (bulk delivery)
Specialized pressurized containers (for safety)
Storage:
Temperature range: Below 30°C (86°F) (to minimize evaporation and pressure buildup)
Keep containers tightly sealed (pentane is highly volatile)
Follow hazardous chemical storage regulations (flammable liquid class)
Keywords： Pentane (Blowing Agent)
