aluminum doors and Windows
Wuhan Yuanfa Plastic Products Co., Ltd. has been firstly certified as “Industry authorized Enterprise” by China Construction Metal Structure Association of Aluminum Curtain Wall Commission and the product PA66GF25 thermal barrier strip becomes “the recommended products cited” in the industry.
Our company undertook and drafted GB-T23615.1 National Standard Accessorial material for architectural aluminum alloy profiles-Part I: Thermal barrier strip of polyamide.
Polyamide PA66GF25 thermal barrier strip has high mechanical strength, high heat and sound insulation, high precision in size.
Product Features
1. With the most advanced extrusion technology in the world, we can satisfiy different
requirements of desigh and ensure the durability of thermal break aluminum doors and
windows and framed curtain walls.
2. The working temperature of the thermal insulation strip is 220°C, Melting Point reaches to
246°C. This enables coating process after assembly of composite profiles;
3. High mechanical strength, able to connect with metal hardware fittings when bearing draw
and shear stress;
4. Excellent product tolerance of less than 0.1mm, ensuring air and water tightness and overall
composite profile dimensions;
5. High corrosion-resistance, weather-resistance, heat-resistance, alkali-resistance and long life
of usage;
6. The thermal expansion coefficient of PA66GF25 is similar to aluminum thus ensures that
product does not affect the integrity of the thermally insulated aluminum profiles;
7. Precisely dimension ensures the lifespan of aluminum extrusion tools, no danger of bending
cracks during rolling, very good knurling effect at the hammer head and easy to assemble.
8. Energy conservation and environment-friendly products; Management Certification: ISO
9001:2008.
