A new mineral filler is being tested by Hedman Resources Ltd. of Toronto.
Hedman said its Superfil 100 and 200 materials are based on nontoxic serpentine ore mined near Matheson, Ontario. Unlike typical serpentine deposits, the Matheson site contains no asbestos, Hedman claims. Serpentine is a form of hydrated magnesium silicate.
Hedman said Superfil provides high-impact strength and improves other mechanical properties without increasing a compound's specific gravity.
The company further claims Superfil is less abrasive than rival materials, reducing wear on machinery.
