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.
we have great advantage especially in thermal break strip for heat insulation aluminium windows,aluminum doors aluminum profile,aluminum fence and curtain wall, etc.
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.


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.
It is mainly used in insulation broken bridge aluminium products, helping to reduce heat loss or heat gain through the aluminum, and has better performance in terms of power usage.
