PA66 GF25 Extrusion Grade Use in Thermal Insulation Strips

PA66 GF25 Extrusion grade material is widely used in the manufacturing of thermal insulation strips, particularly in building applications such as doors, windows, and curtain walls. The main function of thermal insulation strips is to reduce heat conduction and improve the energy efficiency of buildings. Here is an introduction to the use of glass fiber-reinforced PA66 in thermal insulation strips:

1. Material Characteristics:

• High Strength and Rigidity: Glass fiber-reinforced PA66 has excellent mechanical properties, able to      withstand long-term mechanical stress, ensuring stability and durability of the thermal insulation strips under various environmental conditions.

• Low Thermal Conductivity: PA66 itself has a relatively low thermal conductivity. Even with glass fiber      reinforcement, it effectively blocks heat transfer, providing good thermal insulation.

• Weather Resistance and Chemical Resistance: This material resists UV rays, moisture, and chemical corrosion,      ensuring long-term performance of the thermal insulation strips.

• Dimensional Stability: The addition of glass fibers improves the dimensional stability of the material, reducing      thermal expansion or contraction due to temperature changes, and maintaining the structural integrity of the insulation strips.

2. Role of Thermal Insulation Strips in Buildings:

• Thermal Bridge Isolation: Thermal insulation strips are typically placed in the hollow sections of aluminum      windows or curtain walls. They cut off the path of heat transfer between the inside and outside, thereby improving the energy efficiency of the building.

• Improving Comfort: Effective thermal insulation strips help maintain a stable indoor temperature, reduce      condensation caused by temperature differences, and enhance occupant comfort.

• Energy Efficiency and Environmental Protection: Thermal insulation strips made from glass fiber-reinforced PA66 can significantly reduce energy consumption, decrease the use of HVAC systems, and contribute to environmental protection.

3. Advantages of Glass Fiber-Reinforced PA66:

• Superior Mechanical Properties: Compared to traditional unreinforced nylon or other plastics, glass fiber-reinforced      PA66 offers higher strength and rigidity, suitable for high-performance building components.

• Longevity and Reliability: Due to its excellent weather and chemical resistance, glass fiber-reinforced PA66 thermal      insulation strips have a longer service life and lower maintenance costs, maintaining functionality over time.

• Good Processability: Glass fiber-reinforced PA66 is easy to process through extrusion molding, allowing for the creation of complex cross-sectional shapes to meet various design requirements.

4. Application Scenarios:

• High-Performance Doors and Windows: In high-end residential, commercial, and public buildings, glass fiber-reinforced PA66 thermal insulation strips are widely used in aluminum doors and windows to meet energy efficiency and environmental requirements.

• Curtain Wall Systems: In large curtain wall systems, the role of insulation strips is crucial in reducing heat transfer and maintaining a comfortable indoor environment.

In summary, PA66 GF25 Extrusion grade, due to its excellent properties, is an ideal material for manufacturing thermal insulation strips and plays an important role in modern building energy efficiency designs.
