Ramiex

Our strongest natural fibre packing

Description

Versatile, high-performance packing, cross-

plaited from top-quality bleached ramie

fibre yarns that are impregnated with an

advanced PTFE dispersion lubricant. The

result is a consistent packing of uniform

density and compressibility.

Ramie, a tropical nettle plant, produces a

fibre of extreme durability, rot resistance

and significantly greater strength than

flax, cotton or hemp.

Typical applications

Used with great success in the mining

and quarrying industries on reciprocating

pumps working at 300bar with water

containing highly abrasive particles.

Also used for water-based hydraulic

systems, pulp and paper processing

with cellulose slurry, brine circulation,

cooling water systems, and with fluids

that crystallise or contain suspended

solids.
