Materials: combinations of types of copper and polymers best resistant to high temperatures, or sealable within specific temperature ranges.
Dimensions: thickness tolerance +/- 5%; maximum width 650mm.
Formats: pads with outer diameter of 1m max; spools > 30km length.
Mechanical Properties: elongation up to 20% on ultra-thin material (roughly twice as much as market standards).
Surface: copper side of laminate protected with passivating solution (anti-tarnishing protection).
