Product introduction:
Polyamide insulation strip (PA66 insulation strip) is a high-performance engineering plastic material, specially designed for aluminum alloy doors and windows, curtain wall systems, used to block heat conduction between metal profiles, significantly improving the insulation, sound insulation and energy-saving performance of doors and windows.
– Core ingredients: PA66 (polyamide 66) + glass fiber (GF25%-30%)
– Working temperature range: -40℃ to 120℃ (strong weather resistance)
Product features:
1. Excellent thermal insulation performance
– Low thermal conductivity (≤0.3 W/m·K), effectively blocking indoor and outdoor heat transfer, reducing building energy consumption.
2. High strength and durability
– Glass fiber reinforcement (25%-30% GF), tensile strength ≥120MPa, bending strength ≥150MPa, no deformation after long-term use.
3. Weather resistance and stability
– UV resistance, high and low temperature resistance (-40℃ to 120℃), adaptable to extreme climates, excellent anti-aging performance.
4. Safety and environmental protection
– Halogen-free flame retardant (optional flame retardant grade V0), no volatile harmful substances, in line with green building standards.
5. Precise size and adaptability
– Customizable cross-sectional shape (I-type, C-type, T-type, etc.), perfect fit with aluminum alloy profiles, easy to install.
