Classification, feature and application of Masking Tape

What is masking tape

Masking tape is the use of special imported environmental protection substrate, the surface through special treatment, so as to achieve partial shading or complete shading, and back one or two sides of the adhesive tape.
Masking tape is black single/double sided tape with light shading, using a unique printing process to produce black film as the base material, has excellent shielding and insulation.

Masking tape is also known as opaque tape, widely also known as shading material, is a kind of adhesive material can be used for LED and LCD display bezel edge, shielding light source, block light source penetration. 
Its shading performance is superior, the material is soft, paste firm, not easy to become warped. It is a kind of low cost and good effect accessory used on LED and LCD.

Classification of masking tape

According to the material: masking paper tape, masking film tape
According to the color: Bright Silver masking tape, Matt Silver masking tape, Black and silver masking tape, Black and white masking tape, Silver masking tape, White film (white masking tape)
According to the adhesive: single-sided adhesive masking tape, double-sided adhesive masking tape according to the degree of shading: semi-transparent masking tape, completely opaque masking tape.
According to the bottom material: single release bottom masking tape, double release bottom masking tape

Features of masking tape

1. Black PET substrate surface can be matte treatment.
2. Test was done at 180° mountings with 25μmPET myst at a tensile speed of 300mm/min.
3. 1000 level clean environment processing, cleanliness is excellent.
4. Printing with black coating, good shielding.The black coating provides excellent insulation.
Storage temperature: 5-30 ° C Avoid direct sunlight, low temperature (below 0 ° C), high temperature (above 40 ° C), high humidity (above 70%RH) environment.

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 the LCD panel and backlight module fixed, can ensure the normal use of electronic equipment.
2. Masking tape can be applied to block light. In the process of using electronic equipment, it is necessary to apply masking tape, so as to be able to block 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. The matte black surface of the masking tape, but also can have a certain anti-fingerprint performance, that is, in the process of using electronic equipment, will not leave fingerprints on the electronic equipment.

3. It is suitable for mobile phone screen and LCD screen, with black face shading and back reflection function, mainly used for shading and reflection of notebook computer, mobile phone, PDA, LED, LCD and other products, also can be used for light shading of luminous keyboard, ultra-thin advertising light box, backlight board (piece) and other products.

Masking tape used in electronics
The current trend of mobile phone design is to increase the use of functions while ensuring that the product is thin and light. When you use the phone at night or in low light, the LED light placed under the button allows us to see the letters and numbers on the button. Now some mobile phones put a layer of flexible keyboard light guide film between the mobile phone button and the light source. This layer of light guide film can transmit the LED light source evenly and with low loss, so as to reduce energy consumption.
There is also a kind of masking tape related to the LCD screen of mobile phones. The tape is made up of black and white layers. When used, the white part faces the backlight, allowing the light to constantly reflect inside, thus enhancing the brightness. The black part prevents light from leaking out.

Black and white adhesive tape

Black and white adhesive tape, a kind of masking tape, is mainly used in optical display devices to play the role of adhesive and shading, material is PET, two sides coated.

Features of black and white adhesive tape
1. With black and white double color special substrate, white surface light absorption is very little.
2. Good shading performance.
3. It has high adhesive properties for all kinds of sticky materials.

The purpose of black and white adhesive tape is summarized
1. Used to fix LCDS and backlight modules.
2. Used for shading and fixing backlight module and LCD (liquid crystal display).
3. A patch used to attach to the upper side of a light source or to the side of a product.
4. It mainly covers and reflects light.

The application of black and white adhesive tape on mobile phone
Black and white masking tape used for color screen mobile phone backlight, GPS backlight and other electronic display manufacturing industry. It has the advantages of moisture resistance, uv resistance and good shading effect, and medium viscosity, no residue after tearing. Black tape has high density, can completely block the light, and good viscosity, in high temperature and high speed operation is not easy to fragment.

With the rise of smart products in recent years, especially smart phones have become a consumer trend of contemporary young people, and black and white glue as backlight border fixing and shading Die cutting parts, every mobile phone needs to use black and white glue, so the production number of mobile phones is basically the whole backlight industry demand for black and white double-sided adhesive.

The application of black and white adhesive tape in other electronic digital products
Black face excellent shading and white face good reflective, for PET, stainless steel and other high adhesion, weather resistance, aging resistance and punching processing performance.

The electronic industry masking tape not only needs low light transmittance, but also needs strong adhesion, rebound resistance, adhesion and good die-cutting. This kind of tape has a wide range of applications, can be used in notebook and tablet computers (touch screen, Windows block and fixed), smart phones (touch screen and main parts of the shading and parts fixed), TV and monitor (backlight module block, LED light strip fixed) and so on.
