Heat Insulation Nylon Strips Used in Windows
Shape I, shape C, shape T, shape CT and shape HK is the most common shape, we can also according to customer requirements or drawings to customize other special shape.
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.

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.
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.
We have the production capacity of 100000 meters per day. For common specifications, we have molds, and will be shipped in 15-20 working days after receiving the deposit.
