Modified polystyrene board is a specially treated polystyrene (EPS) board with excellent thermal insulation, flame retardancy, impact resistance, and breathability. It is widely used in building exterior wall insulation, color steel sandwich panels, underfloor heating, and other fields.

The production process of modified polystyrene board mainly includes the following steps: first, mix polystyrene particles evenly with specialized modifiers; Then, the mixture is melted, extruded, cooled, and pelletized using an extruder to produce modified polystyrene particles; Finally, the modified polystyrene particles are produced into modified polystyrene boards through foaming molding process.

The advantages of modified polystyrene board are mainly reflected in the following aspects:

Good thermal insulation: Modified polystyrene board has a low thermal conductivity, which can effectively reduce heat transfer and energy consumption.

Superior flame retardant performance: Modified polystyrene board is added with special flame retardants, which have good fire resistance and meet the national A-level fire protection standard.

Strong impact resistance: Modified polystyrene board has high compressive strength and impact resistance, which can effectively resist external impact.

Good breathability: The modified polystyrene board has a microporous structure inside, which is conducive to the discharge of water vapor and keeps the wall dry.

Environmental protection and energy conservation: Modified polystyrene board is non-toxic, odorless, pollution-free, in line with national environmental protection requirements, and conducive to energy conservation and emission reduction.

In summary, modified polystyrene board, as a high-performance building insulation material, has been widely used in the construction field due to its excellent thermal insulation, flame retardancy, impact resistance, and breathability.
