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.
Surfactants are used for controlling the size of bubbles and include silicones, polyethers, and similar materials. Other additives that may be used include cross-linking agents, chain-extending agents, fillers, flame retardants and coloring materials, depending on the application. Polymerization rates for most industrial polyurethanes range from several seconds to about five minutes. Slower reacting formulations can be mixed and molded by hand, but require long cycle times. Faster systems provide shorter cycle times but must use machines for mixing. Polyurethane formulations are generally processed into a wide range of products by reactive molding, spraying, or open-pouring techniques.
PS Recycling machine is mainly used to recycle the high foam polystyrene and high foam polyethene products. PS Recycling machine is the ideal equipment to recycle waste materials. This PS Recycling machine features a compact structure and easy operation. The high foam plastic can be directly used to make granulation without comminuting. At present, the ps recycling machine from Haiyuan plastic recycling machine supplier is the ideal energy-saving equipment.
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.
