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.
The shape HK 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 HK, 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.
