[0002] Extruded board is a rigid foam plastic board made of polystyrene resin supplemented with polymer, which is heated and mixed, injected with catalyst, and then extruded to produce continuous closed-cell foaming. It has an independent closed bubble structure inside and is an environmentally friendly thermal insulation material with excellent properties such as high pressure resistance, low water absorption, moisture resistance, airtightness, light weight, corrosion resistance, super anti-aging, and low thermal conductivity. After the extruded board is extruded, it needs to be cooled and then cut into the required size.
