摘要： The invention pertains to a friction paper comprising filler, para-aramid pulp, and resin, characterised in that the para-aramid pulp comprises 0.1 to 10 wt.% of polyvinyl pyrrolidone (PVP), the paper having a grammage in the range of 100 to 800 g/m2. It has been found that the use of a PVP-containing para-aramid pulp leads to improved friction performance as compared to the use of para-aramid pulp not containing PVP. Effects obtained include improved friction properties, improved strength properties, and improved filler retention.

摘要： The invention pertains to an aramid paper suitable for use in electronic applications which has a density of 0.20-0.65 g/cm3 and a grammage of 30-280 g/m2, which paper comprises 10-40 wt.% of aramid shortcut with a linear density of 2.6 dtex or lower and a length of 0.5-25 mm and 10-90 wt.% of aramid fibrid, wherein the aramid shortcut comprises at least 70 wt.% para- aramid shortcut and the aramid fibrid comprises at least 70 wt.% para-aramid fibrid. It has been found that the use of a paper with the above properties in electronic applications ensures a low CTE in combination with good homogeneity and a good dimensional stability resulting from good resin adhesion and penetration. The invention also pertains to the use of the aramid paper in a composite sheet comprising at least one layer of aramid paper and a resin, or in a substrate board for electronic applications, e.g., in a printed circuit board, or in a backing for a solar cell.

摘要： The present invention pertains to an electrical insulating paper comprising 40-80 wt.% of aramid fibrid, 10-50 wt.% of aramid pulp, and 10-50 wt.% of aramid short-cut, the aramid pulp being para-aramid pulp with a length of 0.5-6 mm and a Schopper Riegler of 15-85. Preferably, the fibrid is para-aramid fibrid and/or the shortcut is para-aramid shortcut. More preferably, the fibrid is para-aramid fibrid, and the shortcut is para-aramid shortcut. It has been found that a paper meeting the above requirements shows an increased value for the product of the dielectric strength (expressed in k V/mm) and the tensile index (expressed in Nm/g), as compared to systems comprising only two of the cited components, or less than 40 wt.% of aramid fibrid. The paper is relatively easy to manufacture, and has good tear strength. The paper is particularly suitable for use in insulated conductors.
