Is hydrogel film good

Mobile phones have now become a necessity in people's lives. The first thing many people do after buying their favorite mobile phone is to put a film on the phone to prevent the screen from being scratched. Mobile phone films have developed from the initial adhesive films to tempered films to the new hydrogel films. Each step represents the evolution of mobile phone films. Tempered glass has the function of anti-falling, so is hydrogel film good? Let’s learn about the function of hydrogel film.

Compared with the hydrogel film, the tempered film with the most users feels closest to naked film, is also very clear, anti-fingerprint and scratch-resistant, and is not expensive. However, one disadvantage is that it is too thick. The popularity of curved screens and 2.5D glass has brought new disadvantages to tempered films besides thickness: because it cannot be bent, it has poor adaptability to curved screens.

So full-screen tempered films and half-screen tempered films appeared. The color around the full-screen tempered film is difficult to completely match the color of the phone itself, and rainbow patterns will appear in the center. Another major problem is that the full-screen tempered film will cover a very small part of the display area at the edge, especially for narrow-frame phones. The half-screen tempered film (i.e. the traditional tempered film) cannot cover the edge of the screen, which looks abrupt and ugly. Later, due to the full adhesion of the hydrogel film, it became the perfect match for the curved screen.

The biggest advantage of the hydrogel film is that it can be moved at will during the application process. You can apply the film on your phone by yourself without having to spend money to find a professional to do it. Even if bubbles appear when you apply the film, the bubbles will automatically disappear after a day or two. Isn’t it amazing?

The ultra-lightness and ultra-thinness of the hydrogel film will not affect its drop resistance at all. It uses the elasticity of Urethane and an adsorption force of up to 570g to firmly wrap the screen, effectively reducing shock by 90%. It also has good anti-fall protection for the increasing number of 2.5D screens.

The user experience is that the touch is sensitive without any drag; the touch is smooth, anti-fingerprint and anti-greasy, and it feels clean and refreshing. Moreover, the curvature of the edges does not accumulate dust and fits perfectly. In addition, it is wear-resistant and scratch-resistant, soft yet strong, and not as difficult to stick as the legend says.

There are many types of TPU and PET hydrogel film materials, but none of them are valuable. Their value depends on the auxiliary materials. Use the least amount of glue to achieve the greatest bonding effect. Then add the material’s self-repairing function, which is the elasticity brought by TPU and auxiliary materials. The ingredients of the spray are water + lubricant + alkaline fragrance base. The product must be specially developed and cannot be copied. The cost of process + materials is about thirty or forty yuan, so there is a reason why hydraulic membrane is expensive.

The main material of hydrogel film, OCA, needs liquid activation and must be assisted by AC spray. The hydrogel film that claims to not spray water is made of benzene pump AB glue, and its adsorption force is only about 100g, which will cause certain damage to the screen.

If the quality is not good and the film is just labeled as a hydrogel film, then it is really speechless! However, it is reported that the real hydrogel film is really easy to use, but relatively speaking, the cheapest one costs about 40 to 50 yuan per piece. The real hydrogel film is smoother than the TPU film that costs a few dollars, and it can be said to have a glass feel. It not only feels good, but also can protect the phone well and is very good at dust prevention. It is a great savior for many curved screen mobile phones on the market.
