It is not like polyethylene or China CASCELL® IH poly Like vinyl chloride and other polymers, monomers need to be polymerized into pellets before they can be processed into products. In particular, rigid polyurethane foam has a particularly low thermal conductivity and is a high-quality thermal insulation Thermal insulation and cold preservation material. The density and hardness of polyurethane foam can be changed with different raw materials and formulations. The current trend is to continuously expand the application fields. During the synthesis of polyurethane, the chemical structure, specification, variety and other adjustment formula combinations of the raw materials can be adjusted to produce terminal products with various properties and uses, such as electrical conductivity, magnetic permeability, high temperature resistance, low temperature resistance, wear resistance, and difficult Products such as combustion, high resilience, slow resilience, high density, low density, reticulated foam, hydrophilic foam, etc. Core material foam, core material foam manufacturer, core material foam price Performance advantages of PMI foam Performance characteristics of PET core foam. Polyurethane is directly processed from monomer raw materials into polymer products at one time, which eliminates the need for polymerization, separation, refinement, and extrusion into pellets. Intermediate process. It has excellent physical and mechanical properties, acoustic properties, electrical properties and chemical resistance.Polyurethane core foam plastics'>Multi-domain applications of core foam plastics: Polyurethane foam has a wide range of applications, almost infiltrating all sectors of the national economy, especially in furniture, bedding, transportation, refrigeration, construction, heat insulation and other sectors. It is very common and has become one of the indispensable materials. In order to save energy in buildings, the Ministry of Construction has promulgated energy-saving measures requiring the use of new thermal insulation materials. Polyurethane core foam plastic sandwich materials are the main varieties to be promoted One, which will further expand the development of polyurethane foam materials., meet the various technical requirements put forward by various industrial fields in the national economy. In addition, in terms of molding construction, other plastics cannot be compared with it. For a long time, the application of polyurethane foam has been mainly used as Pads and thermal insulation materials
