What is the difference between PA thermal break strips and PVC thermal break strips?

PA thermal break strips and PVC thermal break strips are made of different materials, and this difference in material results in distinct performance characteristics. So, when purchasing thermal break strips, how can we tell the two apart? Below, we’ll explain this issue. 1. The surface of a PA thermal break strip is not as smooth as that of a PVC thermal break strip. 2. When snapped, a PA thermal break strip produces a crisp, clear sound, and its fracture surface remains undeformed, allowing it to be rejoined seamlessly. In contrast, a PVC thermal break strip turns white at the fracture point and deforms, making it impossible to rejoin. 3. It takes only one or two snaps to break a PA thermal break strip by hand, whereas a PVC thermal break strip requires about ten snaps.
PA thermal break strips and PVC thermal break strips are made of different materials, and this material difference results in distinct performance characteristics. So, when purchasing thermal break strips, how can we tell the two apart? Below, we’ll explain this issue.
1. The PA thermal break strip does not have the smooth finish of a PVC thermal break strip.
2. When the PA thermal break strip is snapped, it produces a crisp, clear sound, and the fracture surface remains undeformed, allowing it to be rejoined and restored. In contrast, when the PVC thermal break strip is snapped, the fracture surface turns whitish and deforms, making it impossible to rejoin and restore.
3. Breaking the PA thermal break strip by hand requires only one or two attempts, whereas the PVC thermal break strip needs more than ten.
4. For products of the same specification and model, such as I-14.8, the PA thermal break weighs 45.1 g per meter, while the PVC thermal break weighs 57 g per meter.
The above are several key points you can refer to when distinguishing between PA thermal break strips and PVC thermal break strips, with the hope that they will help you select the right type of thermal break strip.
