GRAPHITE EPS INSULATION BOARD
Modified molded polystyrene foam graphite polystyrene board is a polystyrene foam board with closed-cell structure made of expandable modified polystyrene beads after heating and pre-foaming in a mold. It is made from raw materials through processes such as pre-firing, curing, molding, drying and cutting. It can not only be made into foam products of different densities and shapes, but also can produce foam sheets of various thicknesses.

Foam board (common types include polystyrene foam EPS, extruded polystyrene foam XPS, etc.) is widely used in building insulation, product packaging, cold chain logistics and other fields due to its light weight, excellent thermal insulation and cushioning performance, but the deformation problem will directly weaken its function - such as the deformation of the thermal insulation layer reduces the thermal insulation efficiency of the wall, and the deformation of the packaging foam causes damage to the inner products. To solve the deformation problem of foam board, it is necessary to systematically implement measures from the dimensions of material intrinsic characteristics, environmental adaptation, and structural design. The core is to crack the deformation incentives in a targeted manner.
