50% PTFE-impregnated and treated Aramid yarn / 50% Fiberglass
A combination of 50% PTFE-impregnated and treated Aramid yarn and 50% fiberglass. These are twisted together to form individual strands, creating a continuous interaction between the two fibrous elements. The strands are then cross-lock braided. The finished braid is PTFE-impregnated and treated with a silicone oil starter lubricant.
The intimate “all-points” combination of the yarn permits the fiberglass to conduct heat away from the Aramid throughout the packing mass, resulting in increased dimensional stability and constant sealing effectiveness.
- Fiberglass combined with PTFE permeation increases chemical resistance.
- This is a denser, less porous packing than conventional all Aramid styles. Thus, it does not tend to roll in the stuffing box and is less able to extrude.
- Style 50/50 has high run-out deflection.
- Its superior density reduces migration of particles under pressure.
Use as a superior general pump packing in slurries, congealing fluids, vacuum pumps, petroleum products and mild chemicals.
