Jiangsu OptimumNano Energy Co., Ltd. (hereinafter referred to as "Jiangsu OptimumNano") has the composite copper nickel sheet welding patent technology, which solves the problems of multiple cells welding and heat dissipation.
Usually we use 55-degree hardness eva foam sheet to make flooring (many factories use 38 degrees, for higher profit). This hardness foam flooring is durable, but also relatively soft and easy to cut by hand.
