When it comes to the hardness of tablet tempered film on the market, most businesses will say that the tempered film hardness of our tempered film manufacturers has reached 9H, which is guaranteed. When it comes to the classification of tempered film hardness, this is the reason, because The 9H hardness in the 9H package of our actual label really exists, but this refers to the label on the hardness of the pencil, and the label on the Mohs hardness can only reach the hardness of 6-7. It may be close to 9H. Our smart film manufacturers also encountered some situations and explained to customers the hardness of 9H. Most of the customers were in doubt about their performance and expressed that they did not understand. The explosion-proof film, smart film and apple tempered film produced so far are also the same 9H As long as the label is a tempered film, there is a 9H label. Everyone naturally combines 9H with a tempered film over time.
