Polyurethane applications include soft foam, hard foam, reaction injection molding (RIM) elastomers, cast elastomers, as well as soles, adhesives, coatings, sealants, etc., among which foam accounts for the majority, and soft foam accounts for the majority of foam. Soft foam is mainly used in furniture shockproofing, mattresses, the lower layer of carpets, car seat cushions, shockproof packaging, etc. Rigid foam is mainly used in insulation, as a building insulation laminate, which can be compounded with soft materials such as paper, aluminum foil or hard materials such as aluminum or steel plates; Potest etiam esse in refrigerators, freezers, etc., et industriae scelerisque velit; In addition, quod habet applications in packaging, translationem, etc. Rim products sunt maxime usus est in Books industria, inter Dashboards, bumpers, corpus tabulata, vexillum apparatu, et etiam in agriculturae apparatibus, et ludis bonis. Polyureurethane castings sunt maxime in industreriae coronas, Nullam rotae, printer scutulis, TRADUCTOR zonas, pumps, etc. omnia mollis spuma. Post separationem et purificationem, mollis spuma est interficiam in frusta quaedam magnitudine. Et spumam pieces sunt coartur cum tenaces. Et tenaces est a polyurethane factum de Toluene Diisocyanate (TDI) et Diphenylmethane Diisocyanate (MDI) et Polyether Vocatus, et moles usus est X% -20% of moles spumam. Post addendo catalyst, mixta mixta in fingunt ad urgeat et succensa et pressurized curare. Secundum ad applicata pressura, fingitur products cum diversis densities (40-100kg / m3) potest adeptus. Alio modo uti spumam est comminuet mollis spuma in pulveris quandam magnitudine humilis temperatus et miscere pulveris cum polyolmodi. Ad moles ad polyol ad XV% -20% Et Slurry factum de polyolmodi et pulveris est mixta cum isocyanic acidum, tum spumam in spumam dispensando apparatu. Per moderantum moles catalyst et isocyanic acidum, a spumam cum bono perficientur potest adeptus, quod potest esse comparari ad perficientur de spuma ex originali materia.
Praeterea, Polyurethane potest esse subiecta alcoholysis, hydrolysis, fregisset, etc. recuperare Polyollas et related rudis materiae. Potest processionaliter a vapor hydrolysis, glycol hydrolysis, fregisset, etc.
