Produced from 100% electrical grade kraft wood pulp, this grade is referred to in many countries as "Presspahn" and is available in natural buff but can be dyed to achieve any required shade. The production techniques and quality in all cases are identical except that dyed material would contain an innocuous aniline dye.

The excellent physical, electrical and mechanical properties of this grade make it ideally suited for punching, creasing and folding in to components used in an infinite variety of applications.

This is a cotton linter based presspaper which has been developed for customer who need UL approval, low extract levels and the toughness and reliability of a cotton (rag) type paper. This material can also be laminated with polyester films.

With compliance to IEC 641 and UL approval this product is ideal for applications ranging from fractional horse power motors to oil immersed power transformers. It is a popular choice for tag boards, ballasts, bobbins and barriers and many similar applications.

N/B. Special order conditions apply to this grade, please call for further details.

This presspaper exhibits a unique combination of superior electrical strength, mechanical toughness and flexibility and has a proven durability under the most arduous service conditions.

This product finds use predominantly as motor slot and overhang insulation in Class E rotating machines. These laminates are particularly suited for punching, creasing and forming and are used in a wide variety of electrical, domestic and industrial applications.

This grade was developed in co-operation with the power transformer industry to meet the special needs of manufacturers for a major insulation material which provides an optimum combination of electrical and mechanical strength, stability, low permittivity and maximum oil absorption.

The paper is ideally suited for layer insulation, high to low wraps, lead exit protection, petalled ends, layer end packing and can be readily creased and formed in to interlayer wraps with folded edges.

Diamond Dotted presspaper is constructed by applying discrete dots of 'B' resin adhesive to Grade 3 Presspahn. This is a well established methods of producing an insulation system that can enhance the mechanical strength of oil immersed transformer windings without reducing partial discharge inception levels. The adhesive dots are arranged in a pattern that ensures an offset relationship exists between the dots on concentric presspaper layers.

Also available is Grade K diamond dotted.
