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.
Polyols are active hydrogen monomers based on polyesters, polyethers, or hydrocarbon materials that contain at least two active hydrogen atoms. The type of polyol used will determine whether the foam produced is flexible or rigid. Since most polyols immediately react with isocyanates when added together, it is easy to combine the polymerization and shaping processes into one step. During the polymerization proccess, the polyol and polyisocyanate molecules link and interconnect together to form a three dimensional material.
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.
The molecular structure, amount, and reaction temperature of each ingredient determine the characteristics and subsequent use of the foam. Therefore, each formulation must be designed with the proper ingredients to achieve the desired properties of the final material. For instance, a switch in blowing agent may require an increase in this additive to maintain thermal properties. Increasing the amount of blowing agent requires more water and a switch in surfactants to maintain optimum bubble sizes and formation rates during foaming. The density of the foam is determined by the amount of blowing. The stiffness and hardness of polyurethane can also be tailored by changing the level of flexible polyol in the chemical formulation. By mixing different combinations of the starting materials, the rates of the reactions and overall rate of cure during processing can be controlled.
