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.
Shape I, shape C, shape T, shape CT and shape HK is the most common
shape, we can also according to customer requirements or drawings
to customize other special shape.
Detailed Infomation
Advantages
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
hardware.
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'
requirements.
Application
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.
