EPE foaming principlePearl cotton foaming machine is mainly used to produce EPE sheet. LDPE resin is melted and mixed with butane gas, talcum powder, anti shrinkage agent and its color masterbatch. It is extruded by extruder and foamed at die head and die lip. Then it passes through setting circle to fix sheet size. The final product is rolled by receiving roller. Can be made into a variety of sizes and thickness of pearl cotton packaging materials. It can also be used as a special-shaped auxiliary machine to make pearl cotton tube rod, bail type, U-type, V-type corner protector, packaging furniture, door edge, window edge, etc
Pearl cotton, also known as EPE pearl cotton, is composed of numerous independent bubbles generated by physical foaming of low-density polyethylene grease. It overcomes the shortcomings of the ordinary styrofoam, such as friability, deformation and poor recovery. It is a new environmental protection packaging material.
Working principle of pearl cotton net cover machine: extrude Du unit of plastic foam net, add various chemical raw materials such as resin into the material barrel through hopper, heat them up, inject foam gas into the material barrel, mix them with the material barrel, extrude and cool them from the die head, input them into the tractor, cut them automatically to produce Dao sets of different specifications of foam net, or produce them by changing the machine head and die Different specifications of foam rod, foam tube and other products, the adjustment of formula can produce different color and quality of plastic foam products.If you want to know more about it please do not hesitate to contact me.
