Insulation strip is an important part of energy saving and heat insulation for doors and windows. However, some low prices in the market often use PVC insulation strip instead of PA66 nylon strip in order to reduce the production cost of doors and windows, so as consumers, how can we distinguish whether the heat insulation strip is PA66 nylon strip or PVC strip
Insulation strip is an important part of energy saving and heat insulation for doors and windows. However, some low prices in the market often use PVC insulation strip instead of PA66 nylon strip in order to reduce the production cost of doors and windows, so as consumers, how can we distinguish whether the heat insulation strip is PA66 nylon strip or PVC strip?
It is also a black insulation strip. It is difficult for ordinary consumers to distinguish whether the insulation strip is PA66 nylon strip or PVC strip. Here, the editor will teach you three tips:
the first trick: look at it, observe it carefully, and watch the Heat insulation strip from different angles. PVC heat insulation strip is particularly bright, and some PVC heat insulation strips have sculptural feel, PA66 nylon heat insulation strip is cold extrusion technology, the surface is smooth and smooth, and the color is black, and there are Wheel marks pressed by synchronous gears at both ends; PVC strip looks uneven and smooth, and the color is gray and black. Let's take a look through two photos below.
The second trick: fire, PA66 nylon strip is combustible, you can light it with a lighter, the flame is a little light blue, if it is not blown out, it will continue to burn; And PVC insulation strip can also be lit with a lighter, but after leaving the fire source, it will go out by itself.
The third trick: break the heat insulation strip by hand. PA66 nylon strip can be broken by hand, while PVC heat insulation strip is very soft and needs to be broken after repeated for more than ten times, which is not easy to break, when the PA66 nylon insulation strip is broken, the sound is very crisp, while PVC strip will turn white after being broken several times, and there is no sound and it has been deformed.
