Production Description
Over the years, polyamide heat-insulation strip has been widely used in glass curtain walls due to their good properties and low cost. Especially Polyamide 66 reinforced by 25% glass fiber thermal break strips, are inserted into the aluminum window, door and facade profile for thermal insulation.
Polyamide advantages –and a few of their disadvantages – include:
- High mechanical strength
- High toughness, stiffness and hardness
- Good fatigue resistance
- Good impact resistance
- Excellent wear resistance
- Good electrical insulating properties
- No resistance to UV rays
- Lightweight; sometimes used in applications in place of metals
- Excellent fuel and oil resistance
- Attacked by strong mineral acids and absorbs polar solvents
- High water absorption
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.
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.
