Product Description
Polyamide material is the most commonly used for thermal bridge breaking. Polyamide 66 is a semi-crystalline polymer (25% glass fibre) with good mechanical and chemical resistance properties, due to the uniform packing of the molecules in the crystalline region.
This polyamide absorbs the water contained in the humidity of the environment. As the water content within the polymer matrix increases, there is a dimensional increase and changes in the mechanical properties of the polymer.
The shape CT thermal barrier polyamide strip can prevent the window frame from dust and water, has a better mechanical performance, is the first generation and easiest shape of insulating strips.
For the shape CT, we can provide the following size or customize according to customers' requirements.
Advantages
high quality, competitive price, free sample support and short lead time, high mechanical strength, high toughness, high softening point, good wear resistance, self-lubrication, long-term work at higher temperatures, high CTI value, excellent electrical insulation, low smoke and toxicity characteristics.
Application
It is mainly used in insulation bridge aluminium products, helping to reduce heat loss or heat gain through the aluminum, and has better performance in terms of power usage.
