Ps foam sheet extrusion line adopts gentian type double-stage series high foam technology. The raw material is general polystyrene granule. In the extruding process, vesicant is injected into the ps foam sheet machine at high pressure. After extruding, foaming cooling, shaping and hauling off, the ps foam sheet machine can wind to finished ps foam sheet rolls. After the PS foam sheet extrusion line, the finished PS foaming sheet can be made into variety of packaging vessels such as fast food box, aquatic plate, supermarket tray, cake tray, KT board, instant noodle bowl, foam tray etc. It is widely used in the packing of food, fruit advertising, industrial products and so on. This PS foam sheet extrusion line adopts a high speed non-stop hydraulic filter changer and PLC controller, advantages as advanced structure, stable performance, easy operation and high quality.
The liquid chemicals are delivered either by railroad tanker cars or tank trucks and pumped into large holding tanks. From there, the chemicals are pumped into smaller heated mixing tanks, and are kept separate if they react with each other. For continuous manufacture of foam such as slabstock, more than two monomer streams are typically used. Continuous dispensing (also called open pouring or free-rise) is used in the production of rigid and flexible low-density foams. A specific amount of each chemical, measured by metered pumps, is fed from the mixing tanks into a mixing head, where the blending of the chemicals take place. The reactive components are poured onto a moving surface or conveyor belt, where the foam rises and cures to form slabstock.
EPE foam cloth called pearl cotton which is made of polyethene (LDPE), after heating and plasticizing, foaming, cooling, and extrusion process. The characteristics of the material are: Sound insulation, heat insulation, moisture, shock, non-toxic, no smell, plasticity is good etc. It can make 0.5-25mm sheet material. Haiyuan EPE foam machine and pe foam sheet extrusion line can use EPE foam cloth to make all kinds of packing materials and packing materials after the overlying, film-forming. Our EPE foam machine is widely used in electronics, electrical components, handicrafts, daily necessities, glass, ceramics, household appliances, furniture, fruit and other products packaging.
Most foams consist of the following chemicals: 50% polyol, 40% polyisocyanates, and 10% water and other chemicals. Polyisocyanates and polyols are liquid polymers that, when combined with water, produce an exothermic (heat generating) reaction forming the polyurethane. The two polyisocyanates most commonly used are diphenylethane diisocyanate (MDI) and toluene diisocyanate (TDI). Both are derived from readily available petrochemicals and are manufactured by well-established chemical processes. Though MDI is chemically more complex than TDI, this complexity allows its composition to be tailored for each specific application. MDI is generally used in rigid foams, whereas TDI is typically used for flexible foam applications. Blends of MDI and TDI are also used.
