LPG as a blowing agent and process fuel for expanding polystyrene beads into the lightweight foam products used in packaging, insulation, and consumer goods.
Expanded Polystyrene (EPS) manufacturing uses LPG (primarily pentane, a component of LPG) as the blowing agent embedded in polystyrene beads. When heated with steam, the LPG vaporizes and expands the beads up to 50 times their original volume. The expanded beads are then moulded into finished EPS products.
LPG also fuels the steam boilers that provide the process steam for pre-expansion and moulding. BPCL Commercial LPG is supplied to EPS manufacturers producing packaging for electronics, food containers, fish crates, construction insulation boards, and lightweight automotive fillers.
LPG's boiling point and thermal properties make it ideal for controlled, uniform bead expansion.
LPG-fired boilers provide the process steam for pre-expansion and block moulding operations.
BPCL LPG's consistent composition ensures reproducible EPS density and cell structure across production batches.
19 kg and 35 kg cylinders suit small EPS moulders; bulk supply serves large integrated EPS block plants.
Bulk piped LPG supply is also available for high-volume consumers. Contact BPCL to discuss your requirements.
