Product Description Product DescriptionThe PU mould can be a closed mould to expand your PU agent into a block.Users Prepare the formula inadvance and feed them into the box mould,it automatically expand into a block. Users can de mould it by manual lock to open side walls.We equip electrical heating system and insulation layor at mould bottom and walls.It increase the foaming process speed.The heating temperation in the mould can be adjusted.We can also custom its configuration and size as per requirement from buyers.Machine ApplicationPU block size example1200*1200*1000Power Supply380V/220V FAQQ:What PU chemicals needed and how to foam PU block?A:The combination of polyether and Polymeric Methylene Diphenyl Diisocyanate (PMDI) typically refers to the materials used in the production of polyurethane (PU) foam. Here is a breakdown of the chemicals involved:Polyether:Polyether polyols are one of the main components used in the production of polyurethane foam. These compounds are typically created through the reaction of an initiator (such as glycol) with epoxide monomers. Polyether polyols provide flexibility and resilience to the final polyurethane foam product.Polymeric Methylene Diphenyl Diisocyanate (PMDI):PMDI is a type of diisocyanate used in the production of polyurethane foam. It is a mixture of compounds containing methylene diphenyl diisocyanate (MDI), which is a key component in the formation of urethane linkages in polyurethane materials. PMDI is commonly used in the production of rigid polyurethane foams due to its excellent mechanical properties and resistance to fire.When polyether polyols and PMDI are combined in the production of polyurethane foam, the PMDI reacts with the polyols to form the polyurethane polymer network. This reaction is known as the isocyanate reaction and is essential for the formation of the foam structure.The specific chemical structures and compositions of polyether polyols and PMDI can vary based on the manufacturing process, intended application, and desired properties of the polyurethane foam being produced. It is crucial to follow proper handling and safety protocols when working with these chemicals due to their reactivity and potential health hazards.Company Profile
