Understanding XPS Foam Board

huamei Product Page

XPS, or Extruded Polystyrene, is renowned for its superior thermal insulation capabilities and smooth surface, effectively mitigating thermal bridging. Its remarkable Thermal Resistance properties make it a preferred choice in various applications, including Roof Insulation, Wall Insulation, Floor Insulation, Swimming Pools, Heavy Industrial Floors, Cold Storage, Ice Rink Foundations, Logistics Vehicle Manufacturing, and High-Speed Railway Bases.

Technical Specifications of XPS Insulation Board

Key Properties of XPS Insulation Board

Applications of XPS Board

Roof, Wall, and Floor Insulation

XPS foam board is widely utilized for insulation in the industrial housing sector, offering long-term thermal resistance owing to its nearly closed cellular structure that surpasses that of Polyurethane (PU) by approximately 80%. Its exceptional water resistance further enhances its suitability.

Usage in Composite Panels

XPS Insulation Board is effectively employed in decorative and thermal panels, applicable for various structures such as external walls, internal rooms, tunnels, laboratories, hospital partitions, and furniture.

Cold Storage and Logistics Trucks

XPS serves as a thermal insulation board with planed and grooved surfaces, ideal for the manufacturing of Cold Chain Logistic trucks.

Foundations for Ice Rinks and Roads

This extruded polystyrene board can be employed for foundational pavements, including runway constructions and expressways. The lightweight and waterproof characteristics of XPS foam mitigate ground subsidence caused by road leaks, enhancing longevity and safety during extreme weather conditions.

High-Speed Railways and Airport Runways

XPS Board Types for High-Speed Rail Applications

The High Compression X700 Extruded Polystyrene Foam Board possesses a Compression Strength of 700 Kpa and is often used for High-Speed Railway Bases in China. Its role is significant in safeguarding the rail systems against damage from freeze-thaw cycles.

Production of High Compression Strength XPS Board

To achieve a Compression Strength of 700 Kpa, CO2 serves as the blowing agent, resulting in smaller pore sizes and a density of up to 50 Kg/m³. This production process involves maintaining high system pressures in the extruder to ensure CO2 remains in liquid form.

Wind Blade Insulation

This insulation board is also prized for its softness, providing necessary cushioning underfoot while maintaining a Compression Strength of 700 Kpa, aiding in thermal resistance.

Benefits of XPS Foam Board

• Long-lasting thermal resistance
• Durability
• Excellent moisture resistance
• High compression strength
• Remarkable fire resistance
• Outstanding sound absorption capabilities
• Environmentally friendly choice

Fire Safety Ratings of XPS Foam Board

XPS Foam Board must adhere to a minimum fire classification of B2 Grade in China, with B2 corresponding to an Oxygen Index greater than 26. Notably, B1 Grade equates to grades B and C in the European standard, while B2 correlates to grades D and E.

Selecting the Right XPS Board for Your Needs

When installing XPS for building insulation alongside roof, wall, or floor applications, a thickness under 50mm suffices. However, for specialized needs such as Cold Chain Logistics or Cold Storage, thicker panels such as 75mm to 100mm are often required. In such instances, larger extrusion lines with a capacity of 800 Kg/h or more may be necessary.

Transition Away from Freon in XPS Production

The early production of Styrofoam insulation boards utilized Freon-based blowing agents. However, given the environmental impact, manufacturers globally are phasing out Freon in favor of CO2 and other eco-friendly alternatives, contributing positively to environmental protection.

China's HCFC Phase-Out Strategy

• From , Freeze HCFC production and consumption to the average amount of year and set it as a Base Amount;
• By , reduce 10% of the Base Amount;
• By , reduce 35% of the Base Amount;
• By , reduce 67.5% of the Base Amount;
• By , fully stop use of HCFCs.

Factors Influencing Styrofoam Board Pricing

Thickness

Common requirements range from 35mm to 85mm, with more significant thicknesses potentially increasing costs.

Density

Density significantly impacts production costs; higher density correlates to higher pricing.

Surface Finishing

Surfacing options include smooth, grooved, and rough finishes, with smooth surfaces generally being the most economical.

Compression Strength

Compression strength and density are directly related; higher compression strengths typically entail increased costs.

Thermal Conductivity

This property gauges how effectively a material can conduct heat. Lower thermal conductivity values yield better insulating properties.

Fire Ratings

XPS boards are classified into three fire ratings: B1 (Oxygen Index >30), B2 (Oxygen Index >26), and non-flame retardant varieties.

Dimensional Stability

XPS boards exhibit a maximum shrinkage of less than 2%.

Color Options

Available colors for XPS boards include yellow, pink, blue, white, and green, with white being the standard color.

Custom Dimensions

Length does not affect pricing. However, custom dimensions may incur slight additional charges for smaller quantities.

Payment Conditions

Payment terms can also influence pricing levels.

Order Quantity

Bulk orders often lead to the possibility of negotiating for lower prices with manufacturers.
