As part of its agreements with the High Performance Fillers division of the German group Quarzwerke , Provençale SA , 2nd European producer of calcium carbonate to the industry, offers three new product lines.
Aspenger’s Muscovite mica extracted from Austrians deposits and characterized by:
– A layered structure
– A high aspect ratio
– Particle size distribution mastered
– High whiteness
– High purity
– Low oil absorption
– Very low levels of heavy metals
This allows to improve the properties of the finished product , particularly in terms of :
– Reduced shrinkage and cracking
– Improved membership
– Improved resistance to abrasion, thermal shock , weather , aggressive chemical and UV radiation and infrared
– Reduction of the permeability of the film .
All these features allow use in all types of water-based paints , but also in anticorrosion paints as well as for industrial or road paints .
In the field of plastic , mica influences :
– HDT
– Strength and flexural modulus
– Withdrawal
– Chemical resistance
– Permeability
– Dielectric capacity
For plastics applications , the products are available with a surface treatment and are particularly suitable for use in thermoplastic polymers (PA, PBT , PP , PE , PS , for example) but also in the thermoset elastomers and rubbers .
In addition to the classic very white , the « T » series has the advantage, due to its low crystalline silica foams , not to be subject to labeling STOT RE2 – H373 .
This allows easy handling during production operations and the compliance of the finished product with new environmental regulations .
Aspolit
It is a natural mineral filler bicomponent muscovite mica and quartz extracted Austria.
This unique composition enables this filler, usable mainly in the field of coatings , to provide the same characteristics as those of the improved mica quartz ( hardness , abrasion resistance and acid )
Kaolin calcined AD kaolin.
The calcined kaolin is widely used in the paper industry as well as for paints and plastics. It is currently used as an extender for titanium .
This new grade CALK 89/1.3 , made in Central Europe, is characterized by low humidity , a high brightness and a very small particle size .
In addition to the painting area where they have a high opacity , ability flame retardant allows him opportunities in the field of plastics.
