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 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.
Nylon66 Thermal barrier strip of polyamide extruding product, which
is widely used for bridge insulating aluminum profile, has
excellent performance such as high temperature resistance, chemical
resistance, ultraviolet resistance and water resistance. The Linear
Expansion Coefficient of the product is close to that of aluminum
profile, which makes long durance of spacer and aluminum profile.
The product has been tested by the Material Test Center of SGS. The
product meets the National Standard of GB/T23615.1-2009.
1. The Heat Insulation Profiles for windows & doors were
manufactured in line with Chinese national standards GB/T
23615.1-2009, with extremely high mechanical strength and withstand
tensile shear stress, can be acted as the connecter to the
2. The thermal expansion coefficient is the same as that of the
aluminum alloy, which can avoid hesitation thermal expansion and
contraction and lead to the separation between the thermal
insulation strip and the metal.
3. High corrosion-resistance, weather-resistance, heat-resistance,
alkali-resistance and long life of usage.
4. Excellent product tolerance of less than 0.1mm, ensuring air and
water tightness and overall composite profile dimensions.
5. The thermal expansion coefficient of PA66GF25 is similar to
aluminum thus ensures that product does not affect the integrity of
the thermally insulated aluminum profiles.
6. Precisely dimension ensures the lifespan of aluminum extrusion
tools, no danger of bending cracks during rolling, very good
knurling effect at the hammer head and easy to assemble.
For shape, we can customize it according to customers'
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.

The strips will be stored in the ventilated and dry environment,
horizontally placed, paying attention to waterproof, keeping away
from the heat source, avoiding heavy pressure and the contact with
acid, alkali as well as organic solvent.
We have the production capacity of 100000 meters per day. For
common specifications, we have molds, and will be shipped in 15-20
working days after receiving the deposit.
