Nylon Polyamide66 Strips Noise and Heat Insulation Good Quality Used for Sliding Doors and Windows
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 100,000 meters per day. For common specifications, we have molds, and will be shipped in 10-20 working days after receiving the deposit.
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.
