Trapezoidal groove extruded board
- Product details
-
Excellent thermal insulation performance
It has the characteristics of high thermal resistance, low linearity, and low expansion ratio. Its structure has a closed cell rate of over 99%, forming a vacuum layer to avoid air flow and heat dissipation, ensuring the durability and stability of its insulation performance
Excellent high-strength compressive strength:
Due to the special structure of XPS board, its compressive strength is extremely high and its impact resistance is extremely strong. Depending on the different models and thicknesses of XPS, its compressive strength can reach 150-500Kpa or more, and it can withstand various system ground loads.
High quality hydrophobicity, moisture resistance, good stability, and corrosion resistance
In long-term use, it does not age, decompose, or produce harmful substances. Its chemical properties are extremely stable and will not degrade due to water absorption or corrosion, causing its performance to decline. It can still maintain its superior performance in high temperature environments. The product has environmentally friendly properties and does not volatilize harmful substances, which is harmless to human health. The production raw materials are environmentally friendly and do not produce any industrial pollution. 、
application field
Plastic board is often used for building roof insulation, steel structure roof, building wall insulation, airport runway insulation layer, etc. due to its excellent insulation performance; Due to its excellent pressure resistance, it is often used for square flooring, ground frost heave control, central air conditioning ventilation ducts, high-speed railway roadbeds, etc.

common problem
Q
What are the main types of building insulation materials? What are the advantages and disadvantages of each?
A
Advantages: Good fire resistance (Class A non combustible), good breathability, and high stability.
Disadvantages: Slightly higher thermal conductivity than organic materials, higher water absorption rate, and easy generation of fiber dust during construction.
Organic insulation materials (such as EPS polystyrene board, XPS extruded board, PU polyurethane):
Advantages: low thermal conductivity, good insulation effect, light weight, and convenient construction.
Disadvantages: The fire rating is mostly B level (requiring the addition of flame retardants), it is prone to deformation at high temperatures, and its durability is slightly poor.
Composite insulation materials (such as integrated insulation board, vacuum insulation board):
Advantages: Excellent comprehensive performance, high construction efficiency, and some can achieve Class A fire protection.
Disadvantages: High cost and strict requirements for the flatness of the base layer.
Q
How to choose insulation materials suitable for the project?
A
Fire prevention requirements: Grade A materials are required for high-rise buildings (>100m); Low level B1 (flame retardant) is available.
Climate conditions: In extremely cold regions, materials with low thermal conductivity (such as PU, XPS) are preferred; Low water absorption is required in humid environment (such as XPS, foam glass).
Base type: Concrete walls often use boards; Complex shapes can be coated with polyurethane or insulated mortar.
Economy: EPS has the lowest cost; Vacuum insulation board is expensive but thin.
Policy and regulations: B2 level materials are prohibited in some areas, and local standards need to be consulted.
