PET protective film market crisis analysis, tempered glass film will gradually replace PET protective film
What is a tempered glass film? Why is the tempered glass film gradually replacing the PET protective film?
PET protective film market crisis analysis:
The tempered glass film is a new type of protective film for touch screen end users. The tempered glass film will gradually replace the PET protective film. The tempered glass film has high strength, scratch resistance, drop resistance, high definition, smooth touch, sensitive reaction, and can be added Fingerprints and anti-Blu-ray features have many advantages.
Every new industry has its opaque and non-standard phenomenon. At present, the problems of tempered glass film products in the industry are mainly reflected in the following places:
one. Some models do not indicate the thickness of tempered glass
For products made of tempered glass with a thickness of 0.4mm and above, most of the products in the industry (except for online sales) do not indicate or conceal the thickness of tempered glass.
two. Concealing the thickness of AB double-sided tape on tempered glass
Neither the tempered glass film manufacturer nor the tempered glass film trader marks the thickness of the AB double-sided tape used on the tempered glass, resulting in concealing the true thickness of the tempered glass film. The tempered glass film product consists of two parts: tempered glass + AB double-sided tape. The thickest layer of AB double-sided tape is 0.2mm and the thinnest is 0.093mm. The true thickness of the so-called 0.4-thick tempered glass film product in the market is: 0.493 Mm - 0.6mm.
At present, there are only three manufacturers that can provide qualified AB double-sided adhesive quality in the world. The thickness of double-sided adhesive of Kaisimao (Japan) AB is 0.093mm, and the thickness of double-sided adhesive of NiPPA (Japan) AB is 0.125mm. , TMS (Korea) AB double-sided adhesive thickness: 0.2mm.
three. Tempered glass film is not tempered (no scratch resistance)
Tempered glass film is a new type of product. Many people do not understand the product and cannot distinguish the inferior product. The tempered glass film without scratch resistance is mainly because the glass material is made of ordinary glass without tempering, or It is made of plastic glass.
four. Anti-fingerprint tempered glass film does not have anti-fingerprint function
The anti-fingerprint tempered glass film only applies the anti-fingerprint oil on the surface of the glass. The anti-fingerprint function disappears when the hand is wiped off. Because it has the anti-fingerprint function, the cost will increase by more than 30%, based on cost competitiveness. Consider that the tempered glass film in the domestic market does not have a true anti-fingerprint function.
Fives. AB double-sided adhesive material quality problem
The core technology of tempered glass film products is AB double-sided tape used on tempered glass. AB double-sided tape is made of special silica gel based on one side of PET substrate and acrylic side. At this stage, AB double-sided adhesive products with qualified quality are imported (Japan, Korea). In addition to the above three manufacturers from Japan and South Korea, AB and double-sided adhesives from domestic and other manufacturers have many quality problems, such as bubbles. It can't be stuck, the light transmittance is poor, and the touch is not well reacted.
The two double-sided adhesives of Japanese manufacturers use water-grain on the 0.4mm-thick glass. It will disappear automatically after a few hours. The principle is because the 0.4mm glass surface is rough and the phenomenon caused by the silicone exhaust. But it does not affect any use of the end user, accurately speaking, it is not a quality issue.
six. Review
The tempered glass film subverts the concept of the PET protective film. The tempered protective film provides a real protection function, and can add various practical functions such as scratch resistance, drop resistance, blue light prevention and color pattern.
