Product Description

Product Description

Extruded polystyrene (XPS) board is a rigid foam panel manufactured through a thermal extrusion process. Produced from polystyrene resin and additives, it features a continuous, uniform surface and a closed-cell, honeycomb-like structure. As a third-generation rigid foam insulation material, it is widely used in building insulation projects.

XPS board possesses an integral closed-cell honeycomb structure with tight joints and no internal voids; it offers compressive strength ranging from 150 kPa to 500 kPa and thermal conductivity as low as 0.028 W/(m·K). The material demonstrates exceptional thermal insulation performance and compressive strength (up to 220–500 kPa). It is suitable for applications such as building roof insulation and underfloor heating systems.

Product Name	XPS Extruded Polystyrene Board,Extruded polystyrene board, XPS board

Closed-Cell Rate	>99%
Key Advantages	Excellent thermal insulation, high compressive strength, strong hydrophobicity & moisture resistance, lightweight & easy installation, high stability & corrosion resistance, eco-friendly
Service Life	30–40 years with stable performance, no decomposition, no mildew

XPS board is produced by heating and mixing polystyrene resin with polymers, adding catalysts and conducting continuous closed-cell foaming through extrusion. Its internal independent closed-cell bubble structure endows the material with multiple superior properties: high compression resistance, low water absorption, excellent moisture resistance, air impermeability, light weight, corrosion resistance, superb anti-aging performance and low thermal conductivity. It is an eco-friendly thermal insulation material.

Excellent Thermal Insulation Performance

Boasting over 99% closed-cell rate to form an internal vacuum layer, XPS board effectively blocks heat convection and delivers stable, long-term insulation. Outperforming 80% closed-cell rate of polyurethane foam, 20mm XPS board equals the insulation effect of 50mm EPS board or 120mm cement perlite, making it an ideal building insulation material.

Superior Compressive Strength

With a unique structural design, XPS board features outstanding compression and impact resistance. Its compressive strength ranges from 150–500 KPa to withstand diverse ground loads, suitable for geothermal projects, expressways, airport runways, square floors, large cold storage and vehicle interior insulation.

Superior Hydrophobic and Moisture-proof Performance

The stable, gap-free molecular structure of polystyrene resists water absorption fundamentally. It avoids performance degradation caused by water penetration, frosting and freezing damage, maintaining stable insulation and compression performance in low-temperature and humid environments.

Lightweight & Easy Installation

The integrated closed-cell and honeycomb structure endows the board with light weight and high rigidity. It is durable, easy to cut, transport and construct, greatly improving on-site installation efficiency.

High Stability & Corrosion Resistance

Featuring ultra-stable chemical properties, XPS board resists aging, decomposition and corrosion. It maintains intact performance for 30–40 years without mildew or toxic volatilization, adapting to long-term use in various harsh environments.

Eco-friendly & Safe

Made of environmentally friendly raw materials with stable chemical properties, XPS board produces no industrial pollution during production, releases no harmful substances and is harmless to human bodies, qualifying as a green and safe building material.

Main Uses

Roof thermal insulation, underfloor heating, cold storage insulation, and refrigerated vehicle insulation.
