PA66 GF25 windows insulated aluminum parts polyamide thermal break strips.
Polyamide PA66 thermal break strips has high mechanical, high heat deflection temperature,high precision in size.
Because of its great advantages, this kind of material is usually used in insulation broken bridge aluminium products such as or heat insulation aluminium windows and aluminum doors, helping to reduce heat loss or heat gain through the aluminum, and has better performance in terms of power usage.
The shape C 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 C, we can provide the following size or customize according to customers' requirements.
