1. According to the nature: rubberized protective film, self-adhesive protective film
(1) The type of the rubber protective film adhesive is a solvent type rubber adhesive, a solvent type acrylic adhesive, an aqueous acrylic adhesive, and a silicone adhesive. In the meantime, water-based acrylic adhesives are the most widely used products, which can adjust the adhesion slightly, and have good transparency and weather resistance.
(2) Self-adhesive protective film is generally produced by co-extrusion, and its self-adhesive layer is generally EVA, ultra-low density polyethylene or polyolefin plastomer resin. This structural method has gradually become the mainstream of the mall. Because it has more benefits than the adhesive film, such as no residue, stable adhesion, lower the cost of the user and higher profits for the manufacturer of the protective film.
2. According to the classification of glue
Rubber system: natural rubber, styrene-butadiene rubber, synthetic rubber; rubber-based protective film features: soft, can reach the sticky after all; the molecular fluidity is good; relatively easy to tear; natural rubber resistance to aging is poor; the price is higher.
Acrylate type: emulsion type (aqueous), solvent type; acrylate type rubber protective film features:
(1) emulsion type acrylic acid (aqueous acrylic acid): the fluidity is relatively poor, the sticky time is relatively long after arrival, the low viscosity of the protective film will increase the viscosity with time, the environmental protection data, the weather resistance is good, and the speed is fast. Tear film
(2) Solvent acrylic: It is difficult to reach the high environmental standards required, and other characteristics are similar to emulsion acrylic.
3. according to the classification of protective film
PE protective film, PVC protective film, PET protective film, OPP protective film, other protective film
4. according to the protective film shopping mall classification
(1), traditional protective film: such as galvanized steel protective film, colorful steel protective film, glass plate or plastic sheet protective film. Such traditional protective films are mostly of low added value, have low requirements for functions and crystal points, and are mostly rubberized protective films.
(2) Protective film for flat flasher: The application plan includes flat flasher, TFT-LCD module, backlight module, glass substrate and various optical components such as polarizing plate and colorful filter. Such protective film has extremely high requirements for viscosity and crystal point manipulation, and is a high value-added, high-tech threshold.
(3) Protective film for high-tech electronics: such as the protective film used in Dry Film or wafer polishing processes. Such protective films are generally required to be produced in a clean room, and the requirements for crystal points are extremely demanding. Only a handful of protective film manufacturers have the technology to meet these requirements.
HuaLiBao Co.,Ltd adheres to the enterprise spirit of “fine and strong” and the business philosophy of “equality and integrity”, and firmly establishes the awareness of quality brand.
