Dispersed Pigments
Dispersions for PTFE
|
These dispersions are based on naptha and are used to blend in with the PTFE prior to extrusion
along with the naptha mix to form the paste blend of PTFE required for extrusion. The pigments
incorporated in this mix accompany the PTFE through extrusion and sintering, during which the
naptha is driven off leaving the PTFE and pigment blend. The pigments are heat stable under
PTFE processing conditions, yielding bright, vivid colors.
PTFE dispersions are available in two different strengths, the standard series and the light
series that features reduced pigment content.

Low Noise Dispersion (LND) Coatings for PTFE & FEP
|
These are aqueous dispersions used to coat coaxial cable cores of either PTFE or FEP. Two
dispersion grades are offered, one based on PTFE and the other on FEP. The dispersions serve to
reduce RF noise generation in sensor cables during movement. They are applied by dip coating
followed by sintering. The viscosity of this dispersion is balanced to enable proper adhesion
to the core during dip coating. They are compromised of FEP or PTFE resins dispersed in water
with a conductive additive that is bound by the PTFE and FEP following the sintering steps.
For additional processing information, please see the data sheets available from your local
sales office or from this website.
