Crepe paper

Crepe paper

Crepe papers are produced from base papers weighing 25 - 180 g/m2 (15 -111 lbs/ream) and have an elongation of between 15 to 300 %. They are available in master rolls of up 1200 mm and in slit width in a big variety of customer specified inside and outside diameters.  Some of the grades are also traverse wound.

Description

Crepe papers are produced from base papers weighing 25 - 180 g/m2 (15 -111 lbs/ream) and have an elongation of between 15 to 300 %. They are available in master rolls of up 1200 mm and in slit width in a big variety of customer specified inside and outside diameters. Some of the grades are also traverse wound.

 

Features

Insulation class A (105 °C)

· Color natural

· High purity and high oil-absorption

· Good electric dielectric strength

Excellent compatibility with insulating liquids (mineral oils, silicon oils and ascerol oils).

· Free from conductive particles

 

Applications:

Creped Papers are ideally suited to insulate irregular shapes and surfaces where a proper insulation can not be reached with flat papers. Specialities were developed for applications as magnet wire insulation, as layer insulation, in current transformers, in RIP bushings or as shielding material.

 

Available:

Thickness ( Base paper ) : 1.50 Mil (0.04 mm) to 5 Mil (0.125 mm)

Special widths on request
