What is Polyamide Thermal Break Strip (PA66 GF25%)

There are many different materials to produce thermal break strips, such as PA66 GF25%, ASA, ABS, PVC. Among them, polyamide material is the most popular material for thermal break. Thermal insulating profiles made of polyamide PA 66 GF25% (25% glass fiber reinforced polyamide) have significant advantages.

The coefficient of linear thermal expansion (linear elongation coefficient) of the polyamide profiles is equivalent to the aluminum profile. Therefore, the polyamide profile is not subjected to internal stresses after it is pressed to aluminum profile. This is one of the most important advantages of using the polyamide material as a thermal barrier.

Secondly, the deflection temperature of the polyamide profiles under load is high. Even at 200° C for about 15 minutes, no deformation occurs. Therefore, it can easily be heated in the ovens at the powder coating process.

Thirdly, polyamide profiles do not emit toxic gases in case of fire. They are environmentally friendly.

In addition, dimensional stability and resistance to chemicals of polyamide thermal barriers are high.

Why do you need a thermal break?

Why are thermal breaks important? Thermal breaks are essential for any external modern glazing system. Thermal bridging can be responsible for up to 30% of a property's heat loss. This lowers the homes energy efficiency, leading to higher heating bills.

1. Sample water content less than 0.2% by weight.
2. Norm laboratory condition:(23±2)ºC and (50±10)% relative humidity.
3. The specifications marked with "a" only applies to I-shape strip otherwise, the specifications concluded between supplier and buyer through consultation, shall be written in contract or purchase order.

We have been making research and development for special material of PA66 GF25 thermal break strip since 2006. We have a deep understanding and rich experience of the relevant industry during this year.
Before establishing Polywell, we only faced China's domestic market. After starting the foreign trade business, we found that if we only sell raw materials, we cannot achieve an overall solution. Therefore, our company cooperates with the other two companies to research the series of products related to thermal break strips, and we are devoted to providing customers with overall solutions for thermal break strips.

Packaging:

For all shapes, they could be packaged in linear, the length will be 6 meters, or customized.

For some simple shape like "I" and"C", they can be packed in rolls. The length of one roll is around 400-600 meters.

Storage:

According to different storage time and ambient climate, the dimension of PA strips will increase slightly because of the natural moisture absorption. And the mechanical properties will change slightly too.

So, PA strips should be transported and stored under dry conditions away from the influence of weather. (rain, direct sunlight etc.)

Delivery:

shipped in 10-15 working days after receiving the payment
