PA66+GF25 thermal insulation strip(Wuhan Yuanfa)
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 - I Shape strips
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)
Technical Support
To provide the matching and the most advanced production line of thermal barrier materials and the relevant services.
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.Product Performance
GB/T 23615.1-2009 Accessorial for architectural aluminum alloy profiles
Part 1: Thermal barrier strip of polyamide
Based on the Chinese standard GB/T 23615.1-2009 Thermal barrier strip
