Ordinary B3 grade EPS was used as B2 / B1 flame retardant EPS. The use of this kind of inferior insulation board will reduce the fire resistance performance of EPS and increase the fire risk of construction engineering.
Foamed plastic is a plastic with many small bubbles inside the foam. The foam box, or fully automatic foam machine, is a box type packing container made of foam plastic. So what data and equipment do we need to produce EPS foam boxes?
When EPS raw material beads are smashed into production, foaming agent has been mixed in, generally 4-7% pentane. In the mold, high-temperature steam is used for foaming and molding, and up to 98% of the finished product can be air. Beads can be divided into flame-retardant and non-flame-retardant, and can also be divided into large, medium and small according to their radius.
