UL94 V-0 flame class, RoHS 3.0 compliant, Glass-Fiber Reinforced PA66 Thermal Profiles is fully recyclable, 43 % lower CO₂ than PVC.
The low thermal conductivity of PA66GF25 Strips makes them ideal Noise Reduction Thermal Barrier Strips, blocking heat conduction and sound transmission in aluminium structures. They act as a reliable thermal break, cutting building energy consumption and enhancing indoor thermal comfort for residential and commercial projects.
25% glass fiber reinforcement endows our Polyamide Insulation Strips with high tensile strength (longitudinal ≥84MPa, transverse ≥80MPa) and a high modulus of elasticity (≥4600MPa). The strips resist deformation under external stress, ensuring long-term structural stability for aluminium windows, doors and curtain walls.
Our PA66GF25 Strips perform stably in extreme temperatures from -40°C to +120°C, with a Vicat softening temperature of ≥240°C and melting point of ≥255°C. They feature a low water absorption rate (0.1%-0.3%), avoiding expansion or deformation in humid environments, and excellent chemical resistance for harsh industrial settings.
Corona-treated PA66GF25 Window Insulation Bars instantly grip roll-coat adhesive, enabling 3-second positioning and 5× faster assembly than conventional strips, significantly improving production efficiency for aluminium profile manufacturers.
We adhere to strict ISO 9001 quality control throughout production, ensuring homogeneous glass-fiber dispersion for our Weatherproof Thermal Break Strips—a fiber-free surface that perfectly matches anodized color finishes and creates seamless curtain-wall joints. Beyond mechanical and thermal performance, the strips offer superior electrical insulation, preventing arc flashes and leakage currents in electrical equipment. As an eco-friendly solution, our PA66GF25 Strips are fully recyclable, reducing the carbon footprint of construction and industrial projects. Custom extrusion services are also available to meet bespoke size and design requirements for unique project needs.
Homogeneous glass-fiber dispersion gives Weatherproof Thermal Break Strips a fiber-free surface; perfect for anodized color matching and seamless curtain-wall joints.
