The PET silicone screen protector is suitable for mobile phones, computers, and various screen monitors

PET silicone protective filmThere are many types of it, including some anti-static functions, high temperature resistance functions, etc. It has many excellent properties and is widely used in many places. So, what are the characteristics and die-cutting performance of PET silicone protective film? Let's take a look below.

Characteristics of PET silicone protective film

1. Ultra clean: Apply in a cleanroom operating room with a dust level of 1000 (per liter), suspend and dry in a cleanroom operating room with a dust level of 10000.

2. Accurately control the release force of fluorine release film manufacturers: Ion gravure printing technology enables us to precisely control the release force of release films. The current conventional products are very light, light, medium, heavy, and very heavy. The level of demolding force can meet your different requirements for demolding force in die-cutting processing, making your processing both cost-effective and feasible. In addition, we can customize products according to your different needs using the required release force.

3. Moisture prevention: Especially in the humid production environment of southern China.

4. Anti silicone oil dripping: The unique ion gravure printing technology makes the adsorption of silicone oil more firm, and it will not be the same when lifting the tape off the release film. Remove the silicone oil to make it cleaner. Commonly used for lens protective film.

5. Anti static: A surface protective material with the function of preventing static damage

6. Anti slip: The surface of the release film is anti slip, which can make the processed items easy to package and use.

7. Multiple thicknesses: Use different thicknesses to meet the different requirements of processing technology.

8. Multiple colors: a wide variety of types

Silicone protective filmIt is a screen protector mainly used to protect electronic products.

At present, the mainstream silicone protective film is PET silicone screen protective film, which is suitable for surface protection masks, mirrors, glass, etc. of mobile phones, computers, and various screen monitors. A protective mask that is scratch resistant, dust-proof, and radiation resistant.

The silicone protective film adopts a unique imported environmentally friendly electrostatic adsorption silicone layer technology.

This protective film can be divided into: digital product protective film, car protective film, household protective film, food preservation protective film, etc. It is suitable for various screen protectors, computer keyboard protection during production, and surface protection. The surface protection and anti vibration protection of LCD screens and LCD screens should be applicable to the surface protection of electronic displays, instrument surfaces, automotive instruments, and casings. Air conditioning surfaces and various household appliances, metal sealing plates, optical plates, optical resin plates, etc.

With the popularity of mobile phones and other digital products in China, protective films have gradually become the general term for screen protectors. And its functions in the field of screen protectors are also diverse, with the earliest high-definition scratch resistance now favored by OK8 functional protective films. From the earliest PP materials to current AR materials, these materials have undergone many years of development and have gradually been accepted by most mobile phone groups. The silicone protective film mold has high-precision extrusion coating, high cleanliness, no white spots, white mist, sand holes, no wire drawing, no scratches, etc; It has low adhesion, high adsorption force, automatic bubble discharge, fast and high temperature resistance, strong chemical solvent resistance, easy cutting and punching, and can be peeled off without leaving any residual glue.

What is the performance of silicone protective film in terms of die-cutting

The die-cutting quality and method of silicone protective film material are related to factors such as die-cutting equipment accuracy, die-cutting board accuracy, die-cutting blade and material matching.

The die-cutting characteristics of various silicone protective film materials are also different, and the performance of die-cutting silicone protective films is also different. The factors that affect the quality of die-cutting are the type, strength, and thickness of the end face material.

The types of surface materials can be basically divided into two categories: paper and film. It's simple, the cutting process of paper is slightly different from that of film materials. Although theoretically, the surface material and adhesive must be cut together during the die-cutting process, theoretically speaking, die-cutting paper material is the comprehensive result of tool cutting and paper breakage. That is to say, the cutting edge of the UV machine transformer is also squeezed to both sides of the paper. Therefore, the die-cutting accuracy of paper-based materials is not very high. During the analysis process, it is common to see some labels with burrs, which are caused by the relatively coarse and natural breakage of the material fibers.

Based on the die-cutting characteristics of paper materials and considering blade wear, the angle of the flat die-cutting blade is 52 °. Assuming a large angle, the extrusion deformation of the material will be greater, that is, the discriminative power of the horizontal trend will intensify the fracture phenomenon of the material. The die-cutting of film materials is simply the process of completely cutting the spray paint gun. Due to the toughness and non natural fracture of most thin film materials, it is not advisable to cut off two-thirds of the thickness. It must be completely cut off or cut off by four fifths of its thickness, otherwise it will peel off together with the label when it is discharged.

Silicone protective filmThe die-cutting film material should have sharp edges and high hardness. A small angle die-cutting machine should be used, with blade angles ranging from 30 ° to 42 °. Assuming the use of a large angle die-cutting machine, not only is die-cutting difficult, but if the blade is not sharp, the surface material will not be cut, and the backing paper may break, resulting in bleeding of the finished label with shackles on the edges. In short, the precision of die-cutting film is higher than that of paper-based materials. Therefore, die-cutting materials have certain requirements for the accuracy of the die-cutting board and backing paper, as well as the accuracy of the device.
