Nordkalk Wicroll 5

Nordkalk Wicroll 5 by Nordkalk is a high aspect ratio (L/D) wollastonite mineral (white, needle-shaped and naturally occurring calcium silicate mineral with the molecular formula CaSiO₃). It is a reinforcing filler in various elastomers and thermoplastic & thermoset compounds, e.g. in polyamide, polypropylene, polycarbonate, polyurethane and epoxy compounds. As a result of acicular particle structure, wollastonite increases heat deflection temperature (HDT) and flexural modulus and lowers thermal expansion and shrinkage. Moreover, its fine particle size offers excellent impact resistance. The relatively high hardness of wollastonite promotes effective scratch and mar resistance in the end product. Suitable for automotive, household appliance and electric industries. Typical applications of Nordkalk Wicroll 5 include automotive interior, exterior and underhood components.
