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.

Since there is such a wide range of polyurethane chemistries, it is difficult to recycle foam materials using just one method. The majority of recycling involves reusing flexible slabstock foams for carpet backing. Over 100 million lb (45.4 million kg) of polyurethane carpet cushion is recycled every year into bonded carpet cushion. This involves shredding the scrap into flakes and bonding the flakes together to form sheets. Other methods have recently been developed. One method involves pulverizing the foam into granules, dispersing these granules in a polyol blend, and molding them into the same parts as the original. Ground polyurethane can also be added to original systems as a filler in amounts of up to 10%. Another method called press bonding bonds granulated scrap using an isocyanate-based binder into large boards with densities ranging from 400-900 kg/m3.

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.
