The performance difference between PET double-sided tape and oily double-sided tape
There are probably two types of double-sided tapes for high-temperature resistance: one is PET double-sided tape, and the other is oily double-sided tape.
Friends who make double-sided tape should know that both PET double-sided tape and oily double-sided tape can withstand high temperatures. So when should we choose PETS double-sided tape and when should we choose oil-based double-sided tape?
First of all, there are still many differences between PET double-sided tape and oily double-sided tape. First of all, from the perspective of the substrate, the PET double-sided tape is made of PET, while the oily double-sided tape is made of tissue paper. The biggest difference between the two is that the PET tape is continuously pulled and will not deform. On the contrary, the oily double-sided tape is deformed because it is tissue paper and if it is forced, the tape is prone to break. Analyzed from the material, the PET double-sided tape has a high-temperature resistance, which can withstand about 200 degrees, and has quite good thermal stability, while the oil-based double-sided tape is different, and its temperature resistance is about 80 degrees. about.
Secondly, from the perspective of product price alone, the price and cost of PET double-sided tape are generally higher than that of oily double-sided tape. Normally, the price of PET double-sided tape is more than 20 yuan per square, And the price of oily double-sided tape is about 6 yuan a square.
In the end, the two have very different viscosities. The viscosity of oily double-sided tape will gradually weaken overtime after one year and a half. The opposite is true for PET double-sided tapes. Over time, PET double-sided tapes become more sticky and permanently sticky.
