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.
The shape C polyamide thermal insulation strip can prevent the
window frame from dust and water, also has a more beautiful
appearance than the shape I, but not so firm.
For the shape C, we can provide the following size or customize
according to customers' requirements.

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.
Storage Conditions
The strips will 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.
For all specifications/shapes, they could be packaged in linear,
the length will be 6 meters, or customized.
For the Shape "I", "C", and some simple shapes, they can be packed
in rolls. 400-600 meters/roll.
Delivery
We have the production capacity of 100000 meters per day. For common specifications, we have molds, and will be shipped in 10-15 working days after receiving the deposit.
