General Classification

UB-MD–2.6 is made from high purity sulphate kraft wood pulp and carefully selected cotton pulp. This is a relatively soft, flexible and oil absorbent board used where good electrical strength in oil and moderate mechanical strength is desired.

Standard thickness of Solid Board
(in mm) 0.8, 1.0, 1.5, 2.0, 3.0

Thickness between 4.0 and 6.0 mm is supplied on specific request and thicknesses above 6.0 mm upto 50.0 mm are supplied in laminated form.

Standard Sheet Size (in mm)
Width	Length
1160	2200

Tolerances

on Thickness
<= 1.5 mm± 7.5 %
> 1.5 mm± 5.0 %

on sheet size
± 5 mm

Non-standard thickness and sheet size can be produced within the range. However, minimum order quantity will be 2.5 tonnes.
