What is masking tape?
Shading tape is the use of special imported environmental protection base material, the surface after special treatment, so as to achieve partial shading or complete shading, and the back of the single or double coated with strong durable adhesive tape. Shading tape black single/double side tape with shading function, using black film made by unique printing process as the substrate, has excellent shielding and insulation.
Shading tape is also called opaque tape, widely known as shading material, is a kind of adhesive material that can be used for LED and LCD display border wrapping, shielding light source and blocking light source penetration. Its shading performance is superior, the material is soft, the paste is firm, not easy to warp. Is a kind of LED and LCD used on the low cost, good effect of accessories products.

Classification of masking tape:
Divided by material: shading paper tape, shading film tape;
Divided by color: bright silver masking tape, dumb silver masking tape, black silver masking tape, black masking tape (black black masking tape), black and white masking tape, silver masking tape, white film (white masking tape);
According to the adhesive property: single-side adhesive masking tape, double-side adhesive masking tape according to the shading degree: semi-transparent masking tape, completely opaque masking tape;
According to the bottom material, it can be divided into: single release bottom shading tape and double release bottom shading tape.

Features of masking tape:
1, black PET substrate surface can be matt treatment.
2, Polyester film papering at 25 μMPET, peel tested at 180° at a tensile rate of 300mm/min.
3, 1000 grade clean environment processing, excellent cleanliness.
4, the use of black coating printing, good shelter. Black coating provides excellent insulation.
5, storage temperature: 5~30℃ to avoid direct sunlight, low temperature (below 0℃), high temperature (above 40℃), high humidity (above 70%RH) environment placed.

Application of masking tape:
1, masking tape can be applied to electronic equipment LCD and backlight module fixed, for electronic equipment, LCD panel and backlight module fixed is very important, only will be fixed with LCD panel and backlight module, to ensure the normal use of electronic equipment.
2. Shading tape can be applied to shading. In the process of using electronic equipment, it must be applied to the shading tape, so as to be able to shading the electronic equipment. Generally, shading tape are matte black surface, matte black surface also can bring many other benefits for shading tape, for example can make shading tape has certain scratch-resistant performance, good scratch-resistant resistance, can not only make the shading tape on the surface of the beautiful, will not affect the use of the electronic equipment experience, but also can play a protective role of electronic equipment. Matte black surface of the masking tape, but also can have a certain anti-handmark performance, that is, in the process of using electronic equipment, will not leave fingerprints on the electronic equipment.
3, suitable for mobile phone screen and liquid crystal display, with dark shading, reflective back function, mainly used for laptop computers, mobile phones, PDA, LED, LCD and other products of shading and reflection, can also be used for luminous keyboard, ultra-thin advertising light box, back light board (sheet) and other products of shading use.

Commonly used in the electronic field of masking tape:
The current trend in mobile phone design is to add functionality while keeping the product thin and light. When you use the phone at night or in low light, the LED light placed under the phone's keys allows you to see the letters and numbers on the keys. Now some mobile phones put a layer of flexible keyboard light guide film between the phone button and the light source. This layer of light guide film can send out the LED light source evenly and with low loss, thus playing the role of reducing energy consumption.
And mobile phone LCD screen related to there is a shading tape. The tape is made up of black and white layers, with the white part facing the back light, allowing light to bounce off the inside to enhance brightness. The black part prevents the light from leaking out.
▼ and white glue
Black and white adhesive, a kind of masking tape, is mainly used for adhesive and shading in optical display devices. It is made of PET material and coated on both sides.
Features of black and white glue
1, with black and white double color special substrate, white surface absorption is very little;
2. Excellent shading performance;
3. It has high adhesion performance for all kinds of adhesive materials.
Black and white tape use summary
1, used for LCD (liquid crystal display) and backlight module fixing;
2. Used for shading and fixing of backlight module and LCD (liquid crystal display).
3. Paste cloth on the upper side of the light source or the side of the product;
4, mainly play the role of shielding and reflecting light.
The application of black and white glue on mobile phone
Black and white masking tape for color screen mobile phone backlight,GPS backlight and other electronic display manufacturing industry. It has the advantages of moisture resistance, ultraviolet resistance and good shading effect, and moderate viscosity, and does not leave residual glue after tearing. Black tape has high density, complete shading, good viscosity, and is not easy to break in high temperature and high speed operation.
With the rise of smart products in recent years, especially smart phones have become a consumption trend of contemporary young people. As a backlight frame fixing and shading die-cutting parts, black and white glue is needed on every mobile phone, so the production quantity of mobile phones is basically the demand for black and white double-sided adhesive in the whole backlight industry.
Black and white glue in other electronic digital products on the application
Black surface excellent shading and white surface good reflection, PET, stainless steel, with high adhesion, weather resistance, aging resistance and punching processing performance.
The shading tape of the electronic industry not only needs low light transmittance, but also needs strong adhesion, rebound resistance, adaptability and good die-cutting. This tape has a wide range of applications. It can be used in laptops and tablets (touch screen and window blocking and fixing), smart phones (touch screen and main parts blocking and fixing), televisions and monitors (backlight module blocking and LED light bar fixing) and so on.
