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.

PA66GF25 thermal barrier strip

Service Advantages

Design and development of new-model thermal barrier strip

Shortest supply period; normal types available;

Sizes to be determined subject to the requirements of customers (500m/pic)

Product Features

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; High mechanical strength, able to connect with metal hardware fittings when bearing draw and shear stress; Excellent product tolerance of less than 0.1mm, ensuring air and water tightness and overall composite profile dimensions; High corrosion-resistance, weather-resistance, heat-resistance, alkali-resistance and long life of usage; 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; 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. Energy conservation and environment-friendly products; Management Certification: ISO 9001:2008.
