HOMBITEC RM 130 F - Effective inorganic UV-Protection

In addition to visible light, sunlight also contains electromagnetic wavelengths which are not perceptible to the human eye. High-energy UV-A and UV-B radiation, in particular, constitute a significant potential danger to organisms, organic substances and pigmented systems.

Woods used in decorative applications, such as parquet flooring and furniture, are therefore often protected by means of fine particled titanium dioxide when the UV protection system used is required to assure color neutrality and long-term stability.

Protection of the human skin by means of appropriate sun lotions is familiar to us from everyday life. UV absorbers based on fine-particled titanium dioxide long ago proved their efficiency in this respect. These systems are notable for their high transparency, lack of migration hazards and their extremely good absorption performance. This property profile is also indispensable for UV protection in packaging applications.

This high level of effectiveness is achieved by means of systematic adjustment of the so-called micro-rutile to accord with the special technical requirements in this specialized field.



Performance The effectiveness of HOMBITEC RM 130 F can be illustrated using UV/visible spectra. In the visible range, the transparency of an LDPE film extended with 0.5 % HOMBITEC RM 130 F is similar to that of the non protected specimen. In the ultraviolet wavelength range (250 to 400 nm), on the other hand, transmission is reduced as a function of absorber concentration. High energy UV-B radiation is effectively absorbed, in particular.



The properties discussed above make HOMBITEC RM 130 F suitable for all packaging systems in which high transparency, color neutrality and effective UV protection of the packaged goods are needed. The fact that both the inorganic pigment itself and the organic coating possess the necessary approvals means that this product can be used without difficulty in the field of foodstuffs packaging. It goes without saying that this system can also be used in commercial packaging applications.
