Product Description
Over the years, polyamide heat-insulation strip has been widely used in glass curtain walls due to its good properties and low cost. Especially Polyamide 66 reinforced by 25% glass fiber thermal break strips, they are inserted into aluminum window, door and facade profile for thermal insulation.
The shape T polyamide thermal barrier material can prevent the window frame from dust and water, also has a more firmness mechanical performance than the shape I, mostly used on the sash.
For the shape T, we can provide the above size or customize according to customers' requirements.
Advantages
1.Effectively increased thermal in the system property insulation.
2.Reduces condensation on the window.
3.Sound insulated.
4.Improve comfort and living condition.
5.Possible double color coatings provide better aesthetic effect.
6.Various shapes will be designed for the customer's requirements.
7.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.
8.High corrosion-resistance, weather-resistance, heat-resistance, alkali-resistance and long life of usage.
9.linear thermal dilation coefficient almost identical to that of aluminium profiles.
