Production Description
Broken bridge aluminum insulation strip is an important criterion for distinguishing aluminum alloy doors and windows and broken bridge aluminum doors and windows. It is precisely because of the appearance of broken aluminum insulation strips that the aluminum doors and windows of the broken bridge have good thermal insulation and sound insulation performance.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.
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.
According to different storage time and ambient climate, the dimension of PA strips will increase slightly because of the natural moisture absorption. And the mechanical properties will change slightly too.
So, PA strips should be transported and stored under dry conditions away from the influence of weather. (rain, direct sunlight etc.)

1.Sample water content less than 0.2% by weight.
2.Norm laboratory condition:(23±2)ºC and (50±10)% relative
humidity.
3.The specifications marked with "a" only applies to I-shape strip
otherwise, the specifications concluded between supplier and buyer
through consultation, shall be written in contract or purchase
order.
First, Store profiles horizontally in order to prevent bending or twisting the material, otherwise long storage periods cause permanent sagging. Support long lengths.
Second, Maintain ambient temperature in the range from 15 to 20 °C.
Third, Protecting against moisture.
Delivery
For common specifications, we have molds , we can send out the strips in 10-15 working days after receiving the payment.
For special specifications, we have no molds. We need to produce the mold first. Customer should pay for the mold cost.
Packages
For all specifications, they could be packaged in linear, customer
can decide the cutting length.
For the simple specifications like shape 'I' and shape 'C', they
can be packed in rolls. Usually 300-600 meters/roll.
