KUALA LUMPUR (April 9): Supermax Corp Bhd’s operating unit Supermax Healthcare Canada claimed that its masks are made with safe materials and, therefore, do not contain graphene after Canadian authorities issued a recall of disposable masks containing the substance.

"You may already be aware that Health Canada has issued a recall of disposable masks containing a material made of tiny particles called graphene. The agency is advising people not to wear masks with graphene or biomass graphene because its preliminary assessment of the available research suggests the particles cause early lung toxicity in animals, though the risks to humans are not yet known. 

"As a manufacturer, it is our duty to inform and reassure you that all our masks are made with safe materials and therefore do not contain graphene,” Supermax Healthcare Canada claimed in a statement on Tuesday.

According to the statement, Supermax Healthcare Canada, which was founded in 2004, is a division of Supermax.

"Supermax is the second biggest disposable glove manufacturer worldwide,” the statement claimed.

On Bursa Malaysia today, Supermax's share price had fallen 21 sen or 4.31% to RM4.66 at 10.58am, which valued the group at about RM12.02 billion.

Supermax has 2.58 billion issued shares, according to the company’s latest quarterly financial report.
