Wollastonite is one of many fillers that are compounded into PTFE to provide specific properties. PTFE fillers don't act like elastomer fillers, which become chemically bonded to the elastomer. With polytetrafluoroethylene, the high shear modulus fillers are encapsulated and bound by the low shear modulus PTFE.

Wollastonite, a calcium metasilicate (CaSiO 3), has a theoretical composition of 48.3% calcium oxide and 51.7% silicon dioxide but may contain trace to minor amounts of aluminum, iron, magnesium, manganese, potassium, and sodium. It occurs as prismatic crystals that cleave into massive-to-acicular fragments. It is usually white, but also may …

Wollastonite occurs in three different forms, depending on its crystallizationmon Wollastonite is known as Wollastonite 1A, indicating that it is one form of Wollastonite that crystallizes in the triclinic system. The "1A" distinguishes it from two rarer forms of Wollastonite, which are scientifically different minerals since they crystallize differently: …

Wollastonite is a group of innosilicate mineral, formula is CaSiO3 that may inlude small amount of magnesium, manganese and iron substituting for calcium. A valuable industrial mineral, wollastonite is white, gray, or pale green in color. It occurs as rare, tabular crystals or massive, coarse-bladed, foliated, or fibrous masses.
