The industry faces other environmental challenges that will require the development of new blowing agents. Hydrochlorofluorocarbons are scheduled to be phased out in the United States under the Montreal Protocol by the year 2003. Several international efforts may eliminate or even ban HCFCs before this date. The market for flexible foam will continue to expand into nontraditional areas, such as shock absorption, acoustical applications, and toys. This will require improvements in material properties and processes, as well as the development of new chemicals to meet the demands of new applications for other types of foams. A new catalyst has already been developed for semi-rigid foam systems, which lowers densities and fill weights, as well as reduces demold times.
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.
