PTFE Resin / PTFE Fine Powder / High Reduction Rate / Paste
Everflon®PTFE Fine Powder is soft, white polymers that are produced from
PTFE aqueous dispersions.
These fine powders possess the lowest coefficient of friction, the
highest heat resistance, chemical resistance, electrical
properties, and non-sticking properties of all fluoropolymers. It
is uniquely capable of being sheared by lubricated paste extrusion
into a coherent fibrous matrix with useful structural integrity.

Prcessing Guide of Everflon PTFE Fine Powder F1000
Everflon® PTFE F1000 is extruded using a liquid processing aid, such as
naphtha. In the paste extrusion process.
The powder is mixed with a lubricant aid and then compressed into a
cylindrical preform slug under light pressure(1.5–2.0 MPa [220–290
The preform slug is placed in the cylinder of a paste extruder,
where the composition is forced under high pressure through a
finishing die to produce beading, tubing, or wire coatings.
After extrusion, the product is a low-density, but coherent,
fibrous structure. Everflon® PTFE F1000 is usuallyprocessed further, with heat, into a solid
resin product, such as tubing. Heat is applied in two steps, which
maybe taken in-line with extrusion or separately.
Main Application of Everflon PTFE Fine Powder F1000
1.北京两步彩 PTFE F1000 is X is mainly used for wire and cable insulation and
tubes with thin wall tubing, such as spaghetti tubing.
Everflon® PTFE F-1000 must be handled carefully to avoid shearing the powder
prior to extrusion. Fibrillation by shearing is not reversible, and
damaged particles can appear as defects in the finished product. As
temperature is reduced below the transition point of 19 °C (66 °F),
the powder becomes progressively less sensitive to mechanical
damage or compaction in its containers.

Main Processing Way of Everflon PTFE F1000
Everflon® PTFE F1000 is designed for processing at medium to high reduction
ratios (250:1 to 1500:1). It is particularly suitable for
production of wire coating, jacketing, and tubing at fast sintering
