Type HK Extruding Grade PA66 Thermal Break Strip Polyamide Strip in Aluminum Windows
Production Description
Nylon66 Thermal barrier strip of polyamide extruding product, which is widely used for bridge insulating aluminum profile, has excellent performance such as high temperature resistance, chemical resistance, ultraviolet resistance and water resistance. The Linear Expansion Coefficient of the product is close to that of aluminum profile, which makes long durance of spacer and aluminum profile. The product meets the National Standard of GB/T23615.1-2009.
Product Feature
1. 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;
2. High mechanical strength, able to connect with metal hardware fittings when bearing draw and shear stress;
3. Excellent product tolerance of less than 0.1mm, ensuring air and water tightness and overall composite profile dimensions;
4. High corrosion-resistance, weather-resistance, heat-resistance, alkali-resistance and long life of usage;
5. 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;
6. 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.
The shape HK thermal barrier polyamide strip can prevent the window frame from dust and water, has a better mechanical performance, is the first generation and easiest shape of insulating strips.
For the shape HK, we can provide the following size or customize according to customers' requirements.
It is mainly used in insulation broken bridge aluminium products, helping to reduce heat loss or heat gain through the aluminum, and has better performance in terms of power usage.
