Graphite EPS Insulation Board for External Wall System

Product Description

EPS/GEPS molded polystyrene foam is a type of polystyrene foam board with a closed-cell structure, produced by heating pre-expanded polystyrene bead granules and then heating them in a mold. It is made from raw materials that undergo processes such as pre-expansion, maturation, molding, drying, and cutting. This foam can be used to create various types of foam products with different densities and shapes, as well as various thicknesses of foam boards. It is widely used in building exterior walls, insulation, packaging, refrigeration, daily necessities, industrial casting, and more. It can also be used in exhibition venues, storefronts, advertising signs, toy manufacturing, and other applications. To meet national energy-saving building requirements, it is mainly used for external wall insulation, internal wall insulation, floor heating, and other applications.

Product Name	Graphite-polystyrene board
Compressive Strength	≥100 (different applications have varying requirements for strength levels)
Thermal Conductivity	0.032-0.040 W/(m·K)
Water absorption rate (%) (VN)	≤6 (tested after 24 hours of immersion in water).
Main applications	It is widely used in building interior and exterior wall insulation systems, especially for exterior wall insulation projects with fire-proof requirements and the need to use B1-grade polystyrene board.
Storage conditions	It should be placed in a cool, ventilated, and dry place.

Graphite polystyrene board is a new type of insulation board, which is made by introducing graphite into expanded polystyrene. On the basis of maintaining excellent thermal insulation performance, it also has good flame retardant and fireproof performance, and belongs to B1 class flame retardant insulation board. Due to the addition of fine graphite particles, the insulation board made is silver gray. These tiny graphite particles are like mirrors, reflecting heat radiation and reducing heat loss, so the thermal insulation effect of the product is 20% higher than that of ordinary EPS, and the amount can be reduced by 50%.

Excellent thermal insulation performance
Low thermal conductivity: The thermal conductivity of EPS board is between 0.03W/(m. K) and 0.04W/(m. k). The honeycomb structure can effectively prevent heat conduction and provide excellent insulation effect. High energy efficiency: EPS board can significantly reduce the energy consumption of buildings, meeting the energy-saving standards of green buildings.

Good impact resistance board
The material has certain elasticity and impact resistance, can effectively absorb external force and return to its original state, and plays a protective role in construction and packaging.

Lightweight characteristics
The density of EPS board is low and the weight is light, which is convenient for transportation and installation, and will not cause additional burden to the building structure.

Moisture-proof and waterproof performance
The EPS board structure is a closed honeycomb structure, which does not absorb water or has a very low moisture absorption rate, making it suitable for use in humid or rainy environments.

Convenient construction
The material is easy to cut and shape, construction is simple, and it is suitable for various complex shapes of surfaces. In construction, it can be well combined with various bonding materials and finishing materials.

High durability
EPS board is not easy to age and deformation, can maintain good performance for a long time, and the service life is usually more than 50 years.

Main Uses

Used for external wall insulation, internal wall insulation, floor heating, and other applications.
