What are insulation board, extrusion board, EPS, XPS, polyurethane board, phenolic board, and what are their uses, do you know?
Insulation board (including extruded plate, polyurethane board, phenolic board, glass wool board, rock wool board, etc.)
The insulation board is easy to understand, which is the board for building insulation. It includes extruded panels, polyurethane boards, and other boards made of thermal insulation materials.
Polystyrene (Polystyrene, abbreviated PS)
PS is a polymer synthesized by radical polymerization of styrene monomer. It is a colorless transparent thermoplastic with a glass transition temperature higher than 100 C, so it is often used to make disposable containers which need to withstand boiling water temperature, as well as disposable foam lunch boxes, building insulation materials and so on.
EPS (also known as foam board, polystyrene foam board, benzene board, polystyrene board)
EPS board is a kind of white object which is made of EPS beads containing volatile liquid foaming agent and heated and pre-developed in the mold. It has the characteristics of micro-closed hole structure. The white foam used for packaging is EPS.
XPS (also known as extruded polystyrene board, extruded panel)
The full name of extruded polystyrene board is extruded polystyrene foam board, referred to as extruded board, also known as XPS board, extruded polystyrene board. It is a rigid foam plastic sheet made from polystyrene resin with other raw materials, excipients and polymers by heating, mixing and injecting catalysts at the same time, then extruding and pressing. Its scientific name is extruded polystyrene foam plastic for insulation (XPS), XPS has a perfect closed-cell honeycomb structure, this structure makes XPS sheet. Very low water absorption (almost no water absorption), low thermal conductivity, high compression resistance, anti-aging (normal use almost no aging decomposition phenomenon), is a special material for geothermal insulation layer. The picture shows the green feather environmental protection Extrusion board.
Little knowledge: Polystyrene foam plastic is divided into two kinds: expansive EPS and continuous extrusion XPS. Compared with EPS sheet, XPS sheet is the third generation of rigid foam insulation material. It overcomes the complicated production process of EPS sheet and has the superior performance that EPS sheet can not replace.
Polyurethane board (polyurethane, PU or PUR)
Polyurethane is a kind of polymer containing urethane-type repetitive unit in macromolecular chain, which is called polyamino acid ester. PU is a product of polyisocyanate and polyether or polyester polyols in a certain proportion. Polyurethane board is a kind of polyurethane sandwich board made entirely of PU or made of PU and color steel plate. It is mainly used in the external insulation system of industrial and civil buildings.
酚醛板（Phenolic Foam Board)
Phenolic plate (Phenolic Foam Board)
Phenolic board is made of phenolic foam material. Phenolic foam material belongs to high molecular organic rigid aluminum foil foam product. It is foamed by thermosetting phenolic resin. Phenolic insulation boards are widely used in developed countries.
