Kynol Fiber Packing

PA7700 Kynol fiber packing

Braided from high performance Kynol (also named novoloid or phenolic) fiber yarns impregnated with special PTFE
dispersions. It has good mechanical properties combined with softness and strength. Compared to ordinary aramid and
PTFE packing, it has many advantages such as: good thermal stability, low heat expansion; high dimensional stability and
superior pressure resistance even at elevated temperature; high strength whilst gentle to shafts; easy to cut and install;
outstanding chemical resistance especially to acids, organic solvents, oils and fuels.

PA7700 Kynol fiber packing

Braided from pure PTFE yarns and enhanced with Kynol fiber yarns on the corners. It contains the advantages of both PTFE and Kynol.


PA7700 is a high performance packing that is well suited to abrasive mediums and applications where contamination is not
permitted. It has multiple uses in chemical plants and pulp & paper mills, regularly used in rotating and reciprocating
pumps, washer journals, liquor pumps, refiners and digesters.
