The differences between several common insulating glass sealing lines on the market are as follows:
1. PVC material. The insulating glass sealing line of this material is generally made of PVC material;
2. PU material, this material is the most commonly used in insulating glass sealing lines. It is characterized by low price and good wear resistance;
3. TPU residential profile, this is a new type of insulating glass sealing line made of environmentally friendly materials. Its biggest advantage is that it is environmentally friendly and pollution-free;
4. PE polyethylene profile, which is an insulating glass sealing line processed from PE plastic pipes.
The differences between the above four types are only based on their appearance. In fact, their internal structures are the same. They are all products that combine two different substances using hot melt. From a performance point of view, the difference between them is that the thermal conductivity of PVC material is large, so when the outside temperature is low, it will cause indoor heat to dissipate quickly and a cold bridge occurs, while the thermal conductivity of TPU material is small, so it is used in winter When there is no cold bridge phenomenon due to the large temperature difference between indoor and outdoor. In addition, the heat insulation effect of PE type is better than that of TPU, but the price is many times higher than that of TPU.
