Polyamide Thermal Break Strips

25% Glass-Filled PA66 Insulation Strips is primarily made of Polyamide 66 (PA66), a high-performance engineering plastic (nylon). To enhance strength, dimensional stability, and heat resistance, approximately 25% glass fiber (GF) is typically added as reinforcement. Thus, the complete designation is commonly PA66 GF25.

Product Introduction

Polyamide Thermal Break Strips are engineered using high-performance Polyamide 66 (PA66), a robust engineering plastic that offers exceptional durability and resistance to wear. The material’s low thermal conductivity polyamide thermal break strips makes it an excellent choice for preventing heat transfer in building systems, including windows, doors, and curtain walls. To further enhance the strength, dimensional stability, and heat resistance, these strips are reinforced with 25% glass fiber (GF), ensuring superior performance in demanding applications.

These high-strength Polyamide thermal break strips provide long-lasting reliability, preventing outdoor heat from entering in summer and indoor heat from escaping in winter. Their impact-resistant polyamide thermal break strips nature ensures they can withstand physical stress and mechanical impact during installation and long-term use. The weatherproof Polyamide thermal break strips offer protection against harsh environmental conditions, maintaining their integrity even in extreme temperatures and humid environments.

With added corrosion-resistant polyamide thermal break strips properties, these strips are designed to provide durable, long-term performance in both residential and commercial applications. Whether you're constructing energy-efficient windows or reinforcing curtain walls, these long-lasting Polyamide thermal break strips are the ideal solution for improving insulation and optimizing energy performance.

GF25 Heat Insulation Bar boast an ultra-low thermal conductivity of 0.25 W/m·K, making them the core energy-saving component in thermally broken aluminum doors and windows.

Product Advantage

Polyamide Thermal Barrier Profiles significantly improve the insulation performance of windows and curtain walls, dramatically reducing overall building heating/cooling energy consumption.
Glass-Fiber Reinforced Polyamide Strips exhibit minimal dimensional changes due to moisture absorption or temperature fluctuations, with PA66 GF25 material offering excellent wear resistance.
PA66 Thermal Insulation Bars must demonstrate superior UV resistance and anti-oxidation properties to ensure long-term window performance stability.
GF-Reinforced Nylon Insulation Strips show strong chemical resistance against common construction substances (e.g., cleaners, sealants).
As an excellent electrical insulator, Polyamide 66 Thermal Break Profiles are halogen-free, environmentally compliant, and fully recyclable.

Polyamide Heat Insulation bar feature a linear expansion coefficient (CTE) of 3.0×10⁻⁵/K, achieving perfect compatibility with aluminum's thermal movement.
