Production process: pre-foaming → curing → molding
Pre-expansion: Use 80-100℃ steam to heat the raw materials to increase the beads by 40-50 times.
Maturation: The pre-expanded beads are dried in the silo to equalize the internal pressure. The beads will have greater mechanical elasticity.
Molding: The pre-expanded and dried beads are transferred to the mold, and steam is added again to make the beads stick together to form a finished product.
Features: low thermal conductivity, low density, high mechanical properties, low water absorption, easy operation and installation, aging resistance, sound insulation, and buoyancy.
