PORTARYTE® is produced from carefully selected very white, naturally occurring, baryte. The standardised quality of PORTARYTE® is guaranteed by means of an ISO 9001 certified quality management plan. The chemical composition of raw material and product is closely monitored and particle size kept within a narrow variation.

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).
