Types Of Protective Film Glue
- Aug 14, 2018 -

Rubber glue as the name implies, the main raw material is mainly rubber, mainly produced by European and specific Japanese protective film manufacturers, the main feature of the product is more tolerant, that is, a viscous product can be applied to the product surface from smooth to rough, compared to acrylic glue protective film Generally speaking, the viscosity of protective film of rubber type is only about four grades, while the protective film of acrylic glue must be separately classified into one product every 20g/25mm interval, so there are many kinds of protective film of acrylic glue. The protective film is a lot simpler. The second advantage of the rubber-type protective film is also because of its tolerance, so it can be used with a higher viscosity of the protective film, which is particularly suitable for complex applications, such as stainless steel plate, aluminum plate stamping processing.


Acrylic glue


Acrylic glue, also known as pressure-sensitive adhesive, is mainly tincture. Tincture is a kind of polymer active substance. Temperature has a certain effect on molecular activity. The tincture of glue affects the use of adhesive tape directly. Excellent peelability, film cohesion, high transparency, no degumming, no residue in the substrate, suitable for manufacturing low, medium, high viscosity performance protective film. Generally divided into solvent and emulsifying, that is, commonly known as oil glue and water glue. Acrylic glue has wide application scope and good stability in general. The disadvantage is that the exhaust is poor, the response to humidity is greater, but also easier to leave a white fog on the black surface, commonly known as ghost imagination.


Silica gel


The development of silica gel is based on acrylic glue, because in recent years, the demand for surface protection of 3C products is increasing, and a large part of these applications into the so-called after-sales market, that is, the store, and then by consumers themselves DIY. This part of the application, especially emphasis on the special exhaust, so as to avoid the occurrence of bubbles in the film process, and silica gel to meet the needs of this part of consumers, silica gel are used for PET substrate produced by the screen protection paste.
