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.

Advantages of Thermal Insulation System

Effectively increased thermal in the system property insulation;Reduces condensation on the window;Sound insulated;Improve comfort and living condition;Possible double color coatings provide better aesthetic effect.

Packing specification

The products, with a length of 6m for a piece, 100 pieces for a bundle, are packed with transparent plastic film. As required by the customers, 10000 meters in one package, with 500m/pic each.

Storage Conditions

      It is suggested that the product be stored in the ventilated and dry environment, horizontally placed, paying attention to waterproof, keeping away from the heat source, avoiding heavy pressure and the contact with acid, alkali as well as organic solvent.

Each YUANFA strip comes with a laser marking
