About Packaging product supplier in Bangladesh
Expanded polystyrene, or Packaging product supplier in Bangladesh for short, is a simple material with a unique combination of qualities. It offers high resistance to the passage of heat energy-it is a very effective insulator. It is also economical, offering high R-value per dollar.
Packaging product supplier in Bangladesh (EPS) are commonly known as bead boards. The raw material is a small bead. These are heated with steam and the softened plastic expands as the pentane gas trapped in the plastic beads expands. These pre-expanding beads are then cured during an aging process. The cured beads are then introduced to a mold where further contact with steam softens and expands the beads to fill the mold cavity and fuse the beads tightly together. The molded foam can be in large rectangular blocks that are further processed by cutting with hot wires into standard sized sheets or custom-cut billets. This is known as block molding. The basic EPS blocks are cut and shaped to produce a variety of True Foam sheet(Cocksheet supplier), board and panel products including True Wall, True Fit, Foundation Plus/Sheathing, Insul Wall, and others.
For certain true foam products, such as Reward Wall ICFs and Styropack shipping containers, the polystyrene is shape molded during final expansion.
Packaging product supplier in Bangladesh is structurally rigid and stable, yet very light. It is very easy to cut and shape using the simplest of tools. It produces no irritating fibers or annoying dust. EPS products make the job quicker for both contractors and do-it-yourselfers.
EPS insulation doesn’t change or deteriorate over time. EPS sheets(Cocksheet supplier) and panels cannot sag or bunch. EPS insulation is unaffected by freeze-thaw cycles and cannot rot or mold. EPS insulation’s R-value is permanent.
EPS insulation is very resistant to the passage of water, yet it “breathes”. Vapour passes through, which avoids condensation buildup within walls. This prevents a serious problem which can arise with other insulation systems. Due to the rigid closed-cell structure of EPS, there is no possibility of air movement inside the wall which can lead to heat loss in loose or blanket materials.
