EPS insulation board and XPS insulation board are two insulation boards with very similar names. What are the differences? Let us introduce them to you.
The main component of EPS is polystyrene resin , which is a foam material with a closed-cell structure formed by foaming and molding. XPS is a rigid foam material with a closed-cell structure made of polystyrene resin or its copolymer as the main component,
with a small amount of additives added, and is made by heating and extrusion.
1. XPS insulation board is an extruded polystyrene thermal insulation board. It is made of polystyrene resin as the raw material, plus other raw and auxiliary materials and polymers, and is heated and mixed while injecting a catalyst, and then extruded and pressed to form a rigid foam plastic board. Its scientific name is extruded polystyrene foam for insulation. XPS has a perfect closed-cell honeycomb structure, which makes the XPS board have extremely low water absorption, low thermal conductivity, high compressive resistance, and aging resistance.
2. EPS polystyrene insulation board: EPS polystyrene insulation system is a system that integrates thermal insulation, insulation, waterproofing and decorative properties. EPS insulation board is made of polystyrene particles as raw materials and is pre-foamed after being heated. A plate that is heated and formed in a mold. The main features are good thermal insulation performance, significant energy saving effect, significant waterproof and crack resistance performance, which can protect the main structure and extend the life of the building.
3. EPS insulation board is a board made of polystyrene particles as raw material, pre-foamed by heating and then heated and formed in a mold. The main features are good thermal insulation performance and significant energy saving effect. The EPS polystyrene insulation system is a system that integrates thermal insulation, heat insulation, waterproofing and decorative properties.
EPS (polystyrene) insulation board and XPS (extruded polystyrene) insulation board are two common types of building insulation materials, and they have some obvious differences.
EPS insulation board is a plate-shaped material processed by expanded polystyrene particles.
Has the following characteristics:
1. Low thermal conductivity and good thermal insulation performance;
2. The price is relatively economical and suitable for large-scale use;
3. Lightweight, easy to construct and process;
4. Recyclable and environmentally friendly.
However, EPS insulation board is slightly inferior to XPS insulation board in terms of compressive strength and water absorption.
XPS insulation board is a high-density board made by extruding extruded polystyrene particles at high temperature.
It has the following features:
1. Lower thermal conductivity and better insulation effect;
2. Strong compressive resistance, suitable for basements, roofs and other places that need to bear weight;
3. Long service life, good durability, not easy to age;
4. Strong resistance to water absorption and high stability.
However, the price of XPS insulation board is relatively high and not suitable for large-area applications.
In general, EPS insulation board is suitable for occasions with low insulation requirements and economical and affordable, while XPS insulation board is suitable for occasions with high requirements for insulation performance and durability. When choosing, it is necessary to comprehensively consider factors such as insulation effect, quality requirements, budget, etc. according to specific project requirements to determine the most suitable insulation material.
