Our PA66GF25 Thermal Barrier Strips benefit from 25% glass fiber reinforcement, delivering a longitudinal tensile strength of ≥84MPa—far exceeding standard nylon strips—and exceptional dimensional stability, resisting deformation even in extreme temperatures ranging from -40°C to ≥220°C. The strips feature low water absorption, ensuring long-term reliability in humid indoor and outdoor environments, while their RoHS-certified, non-toxic composition makes them eco-friendly and aligned with global green building trends. All raw materials are high-grade PA66 GF25 granules, guaranteeing the inherent quality of each strip.
The specialized polyamide formula of PA66GF25 Thermal Barrier Strips minimizes thermal conductivity, significantly reducing heat transfer between aluminum structural components and cutting building energy consumption by over 30% compared to uninsulated aluminum profiles. The innovative multi-chamber design further optimizes insulation efficiency by blocking thermal bridging, making the strips a perfect choice for high-performance energy-saving building envelopes.
These strips boast superior UV resistance, withstanding over 30 years of outdoor exposure without aging or performance degradation—outperforming traditional PVC thermal break strips by a wide margin. They also feature excellent aging resistance, maintaining a transverse tensile strength of ≥60MPa after accelerated aging tests, ensuring long-lasting performance in harsh weather conditions such as rain, snow and extreme temperature fluctuations.
Certified Quality Assurance: Our PA66GF25 Thermal Barrier Strips hold ISO 9001 quality management and ISO 14001 environmental management certifications, complying with international construction and environmental standards for global application.
Exceptional Noise Reduction: Windows and curtain walls fitted with our strips achieve 30dB noise insulation, creating quiet and comfortable indoor environments for residential and office buildings.
High Precision & Customization: Dimensional accuracy is guaranteed within ±0.05mm via high-precision molds and random production inspections; we also offer customized laser printing and tailored dimensions to meet specific project requirements (standard color: black).
20 Years of Manufacturing Expertise: With two decades of focus on polyamide thermal break strips, our automated production lines support mass and custom production, with factory-direct pricing eliminating middlemen for cost-effectiveness.
Specialized in manufacturing PA66GF25 Heat Insulation Bars for 20 years, equipped with 20 automated production lines, supporting customized production.
