Datong extruded board wholesale sells high quality extruded board

???Polystyrene foam is divided into two types: expansion type and continuous extrusion type. Compared with boards, boards are the third generation of rigid foam insulation materials. Technically, they overcome the complicated production process of boards and have the advantages of Superior performance that cannot be replaced by boards. It is a plate made of polystyrene resin and other additives through an extrusion process with a continuous and uniform surface layer and a closed-cell honeycomb structure. These thick plates with a honeycomb structure have no gaps at all. This closed-cell structure The insulation material can have different pressures (-) while having the same low value of thermal conductivity (only ./.) and long-lasting excellent insulation and compression resistance, with a compressive strength of up to -. The insulation board is an extruded polystyrene insulation board. It is made of polystyrene resin as raw material plus other raw materials and polymers. It is heated and mixed through a special process while injecting a catalyst, and then continuously extruded and molded. The manufactured rigid foam board, whose scientific name is extruded polystyrene foam for thermal insulation (abbreviation), has a perfect closed-cell honeycomb structure. This structure allows the board to have extremely low water absorption (almost no water absorption). ), moisture-proof, airtight, lightweight, corrosion-resistant, low thermal conductivity, high pressure resistance, anti-aging (almost no aging decomposition during normal use), long service life, low thermal conductivity and other excellent performance energy-saving and environmentally friendly insulation Material. Its mechanical properties are unmatched, plus its tight closed-cell structure due to continuous extrusion. Its density, water absorption, thermal conductivity and steam permeability are lower than other types of boards, and it is currently a recognized thermal insulation material in the market. 3 king managers of sales calls
