Imerys NYLITE® Wollastonite in Polypropylene
Categories: Polymer; Thermoplastic; Polypropylene (PP)

Material Notes: Data for polypropylene reinforced with 15% Nyco NYLITE® Wollastonite. Polypropylene used is Braskem TI6200Q High Impact Copolymer 20 MFR -NB

Wollastonite (calcium metasilicate, or CaSiO3) is a naturally occurring white, non-metallic mineral with an acicular or needle-shaped crystal structure. This distinctive property makes wollastonite an ideal performance mineral for a broad range of industrial and consumer applications.
