Portaryte® micronized functional fillers are used in a broad range of applications. The most important characteristics are:
- excellent chemical inertness (outdoor and chemical applications)
- low level of impurities, such as transition and heavy metals
- low content of quartz (low abrasiveness, no health issues)
Because of these characteristics, Portaryte® fillers are successfully used in an extended range of paint & coating applications such as industrial, marine and powder coatings.
Portaryte® fillers are also used in various industrial sealant and adhesive applications due to their excellent chemical resistance. The exceptionally high density of baryte makes Portaryte® a filler of choice for sound deadening in automotive and domestic applications (e.g. polyolefin sewer pipes)
