What is the main purpose of PU protective film

PU protective film is based on transparent PET and coated with polyurethane adhesive. It has high-quality lubricity and zero pollution to pasted raw materials. It is especially suitable for maintaining touch display screen in the whole process of production, manufacturing and transportation, and is also suitable for maintaining intelligent machines and flat plates in the whole process of transportation.

Electro-optic PU protective film has excellent adsorption force and excellent reliability. Electro-optic PU protective film will gradually replace silicone protective film and become the main force in the sales market of touch screen protective film.

Its key uses include a number of levels:

Maintain smartphones and tablets throughout the delivery process?

Control panel, manufacture and maintenance of laminated glass for spectacle lenses?

Maintain the touch screen throughout the delivery process?

PU protective film characteristics:

A high-temperature protective film with environmental protection PET as the base material and sizing PU glue to make it have low adhesion, can cater to long-term, and is not easy to open glue after removal.

Product features: high transmittance, strong aging resistance, low adhesion and very easy to tear, no residual glue, heat resistance;

Commodity characteristics: high cleanliness level, strict manipulation of dirty things; It has high-quality adhesive characteristics for the pasted object. After pasting, it will be separated from the glue stain, and the commodity definition will be above 90%;

PET is the base material polyurethane adhesive system to form electronic optical protective film products. Its repeated application and excellent sealing performance can be used for maintenance of various electronic optical materials. Compared with the traditional protective film, it has low pollution and is especially suitable for deep processing of ITO glass for touch display screen. Its characteristics are better than those of silica gel protective film. The key is to deal with the fog of silica gel protective film and the problem of partial glue opening.
