Abstract. Wollastonite is a metasilicate having an inosilicate (chain silicate) structure. It belongs to the pyroxenoid group of minerals. It is the only white acicular mineral and became famous and widely used in the industry in the 1970s 1980s as a nonhazardous replacement for asbestos fibers.

Wollastonite has found applications in both thermosets and thermoplastics. Typical wollastonite loadings in plastics include: nylon (50%), low-density polyethylene (40%), polypropylene (23-28%) and polystyrene (30%). Wollastonite is used in plastics mainly as a cheaper alternative to other fillers such as short-milled fiberglass, mica and talc.
Jul 15, 2008· Wollastonite: Quarzwerke , TREMIN 283-800 EST-M: Treated with Epoxysilane 72 (vol.%) below 4 μm: All minerals listed here except nephelinsyenit, silica beads and wollastonite are minerals of biogeochemical and climatic interest. The later samples were specifically considered to test the methodology presented here.
Wollastonite has a theoretical composition of 48.3% CaO and 51.7% Si02, although aluminium, iron, magnesium, manganese, potassium or sodium may partially substitute for calcium (Harben & Bates, 1984; Virta, 1995). The chemical compositions of com-mercial wollastonite products from several countries are summarized in Table 1.
TREMIN® wollastonite is a naturally occurring calcium silicate that is formed from quartz and calcium carbonate at a temperature of about 450°C. There are two aspect ratio grades manufactured which are used in different situations.
TREMIN has been used for many years as a functional filler for improved tensile strength and dimensional stability in flouroelastomers to set the degree of hardness. In addition, provides exceptional pigment coloring and high tear resistance. ... Natural Wollastonite treated. Tremin® 283-600 AST. Tremin® 283-600 EST. Tremin® 283-800 AST ...
It is also easy to pigment these rubbers when using wollastonite. Let us compare the effectiveness of the aminosilane treated wollastonite (TREMIN® 283-600 AST), with an MT N990 carbon black. If you would like to view the datasheet for TREMIN® 283-600 AST then this can be found on our TREMIN.
TREMIN® 283-600 EST is a surface-treated filler that is produced from natural wollastonite by iron-free grinding with subsequent air separation and coating with an organo-silicon compound. It is treated with epoxysilane. This product has an average grain size of 3.5 μm.
The Hazard fields include special hazard alerts air and water reactions, fire hazards, health hazards, a reactivity profile, and details about reactive groups assignments and potentially incompatible absorbents.The information in CAMEO Chemicals comes from a variety of data sources.
TREMIN®283 is the name for a surface-treated filler that is produced from natural wollastonite by iron-free grinding with subsequent air separation and coating with an organo-silicon compound. The type of surface treatment is defined by the following three-letter code added to the characteristic grain data:
