KEJIA XPS extruded board, full name of extruded polystyrene foam board , is a new type of board with closed cell honeycomb structure made by continuous extrusion molding process with polystyrene resin as the main raw material, polymer auxiliary materials and catalyst added.

Its interior is an independent closed bubble structure, which is an environment-friendly thermal insulation material with excellent performance such as high compression resistance, low water absorption, moisture-proof, airtight, light weight, corrosion resistance, anti-aging (30-50 years of long-term use), low thermal conductivity, etc.

Kejia Energy saving will analyze the characteristics of XPS extruded board for you. Its core advantages are reflected in four aspects: thermal insulation, compression and waterproofing, lightweight and durable, and environmental performance:

Excellent thermal insulation performance

1. Low thermal conductivity: The thermal conductivity is only 0.028W/(m · K), far lower than traditional insulation materials such as EPS board (expanded polystyrene) and foamed polyurethane. The insulation effect of 20mm thick XPS board is equivalent to 50mm thick foamed polystyrene or 120mm thick cement perlite, significantly reducing material usage and building load.

2. High closed cell rate: With a closed cell rate of over 99%, a vacuum layer is formed to effectively prevent air flow and heat dissipation, ensuring long-lasting and stable insulation performance. Compared to the 80% closed cell rate of foamed polyurethane, XPS boards are less prone to performance degradation due to air infiltration during long-term use.

Excellent compressive and waterproof performance

1. High compressive strength: Depending on the model and thickness, the compressive strength can reach 150-700kPa and can withstand ground loads, vehicle crushing, and other scenarios.

2. Moisture proof and Waterproof: The water absorption rate is extremely low (volume water absorption rate ≤ 1%), and the polystyrene molecular structure does not absorb water. The board has no gaps, effectively solving problems such as water leakage, penetration, frosting, and condensation. It can still maintain insulation performance and structural integrity in humid or low-temperature environments.

Lightweight and durable, easy to construct

1. Lightweight texture: The fully closed cell foam structure and honeycomb like physical structure endow the board with lightweight and high-strength characteristics, making it easy to cut, transport, and install. It has high construction efficiency and is not easily damaged.

2. Strong durability: chemically stable, does not age, decompose, or produce harmful substances, with a service life of up to 30-60 years. In high temperature or high humidity environments, it can still maintain excellent performance without mold or harmful substances.

Outstanding environmental performance

1. Material environmental protection: The production materials are made of environmentally friendly materials, which do not produce industrial pollution.

2. Recyclability: Solid waste materials formed during the production process can be recycled and reused, meeting the requirements of sustainable development.

Application Scenario:

XPS extruded polystyrene board is widely used in building roofs, exterior walls, ground insulation, as well as transportation fields (such as roadbeds, parking platforms, airport runways, etc.), cold storage, car interior decoration insulation and other scenarios. Its lightweight, high strength, insulation, and waterproof characteristics make it a cost-effective choice in modern architecture and engineering fields.
