Magic Paper is a unique product.
Magic Paper is made up of many layers of polypropylene and voids filled with gas and charged with electricity. This construction makes it possible for the permanent electric charge to stay inside of the film. The electric field contained in Magic Paper produces an adhesion force, which creates an adhesion force with most common types of surfaces - wall, window, wood, and stone. This process should not be confused with a static charge; it is a totally different process. The process of introducing the electrical charge into Magic Paper is a proprietary process.
Previous technology used a charge which is only on the surface of the film. The old technology lacks the major features of Magic Paper i.e. level of magnetism, the adhesive charge is one fourth, the paper cannot be printed and it looses its adhesive power within a short period of time, it is not suitable to be hung on walls more than once, cannot be used as posters, etc.
After an initial decrease in adhesion force just after the production, the adhesion force of Magic Paper remains relatively constant for long periods of time after the product has been delivered to a customer. In field tests, periods of adhesions of more than five years have been observed.
Magic Paper is recyclable as Polypropylene (PP) is a polymer containing carbon (C) and hydrogen (H). When polypropylene is burned, heat, water (H2O) and carbon dioxide (CO2) is produced. No toxic gases are released in the burning process.
The grade of polypropylene used contains some titanium oxide, which is used to enhance the whiteness of PP, and hence, to increase the resistance of the Magic Paper to UV-light.
Magic Paper uses standard polypropylene (PP), the following physical properties apply:
- Temperature limits: HIGH 107 C - LOW -57 C
- Melting temperature 170 C
Resistance to:
- strong acids - excellent
- strong alkalis - excellent
- grease and oils - good to excellent
- organic solvents - good
- high relative humidity - excellent
- sunlight fair - good
The recommended highest usage temperature for Magic Paper for longer periods of time is 60 C.
