Multi Cavity Thermal Break Profile Nylon 66 Heat Insulation Strip Polyamide Building Material
HK 14.8-35.3mm Nylon Thermal Break Insulator
Production Description
Multi-cavity polyamide profile for windows and doors. Used on curtain wall system, or in facade system, and being the part of energy-saving window system for reducing heat conduction. Shapes can be customized, we're majored in developing polyamide profiles for window system.
For the shape HK, we can provide the following size or customize according to customers' requirements.
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.
